Preface — About This Manual

PURPOSE AND SCOPE

This manual describes the installation and day-to-day operation of the ATC-1000™ Advanced Traffic Controller. It discusses the options available for I/O and D modules for the controller. It does not cover the modem and communications card options that are available for the optional 2070 modem slot or other external devices, as too many options exist. For such items, please refer to the documentation that is supplied.

ASSUMPTIONS

It is assumed that the reader and user of this manual, the hardware, and the software tools described herein are authorized to work in and around traffic cabinets by the local traffic governing body. The reader should be familiar with the operation and wiring of traffic control cabinets in their area, and must be aware of, and follow, all safety and security protocols of the traffic agency. It’s also assumed that the operator of the ATC-1000 traffic controller is aware of what signal standards are being used inside the cabinet (NEMA TS 1, TS 2, NTCIP, Simple output, etc.) and follow those standards.

The Peek ATC-1000 uses the following standards:

National Electrical Manufacturer’s Association (NEMA) TS1 – NEMA is a North American trade organization that first defined the TS1 standard in 1978. This standard was formally declared obsolete in 1992.

NEMA TS2. This standard replaced the TS1 standard in the United States and Canada. The current published standard is TS2-2003. It specifies operational features and interchangeability requirements for manufacturers.

Preface — About This Manual

2 ATC-1000 Advanced Traffic Controller

Advanced Transportation Controller (ATC). The ATC standard, currently at Version 5.2b, published on September 25, 2006 was defined as a new standard integrating some features of TS2. ATC is primarily a North American standard. It was defined by a joint committee that included the U.S. Department of Transportation, AASHTO (the American Association of State Highway and Transportation Officials), the ITE (Institute of Transportation Engineers), and NEMA.

Wherever standards do not define the operation of the controller or the cabinet system, Peek went into the design process for the ATC line of controllers with the strategy to create a proprietary system that uses the best practices and reliable, leading-edge technologies available for each application. This is particularly true of the Peek ATC Controller’s Preemption, Transit Signal Priority, and Interval-based traffic engines.

Controller Firmware This manual was written to describe the Peek ATC-1000 Controller using firmware version:

3.5 Build 304 If your controller is running firmware other than the version listed above, there may be some differences between the screens and functions described here and the screens and capabilities of your controller.

OVERVIEW

This is a picture of the ATC-1000 controller, with a TS2 Type 1 Input/Output module installed.

Figure 1 – The ATC-1000 traffic controller

The ATC-1000 is a multi-standard traffic controller. It will fit into a variety of traffic control cabinets, based on the hardware installed and the software settings used. It can function as either a phase-based (NEMA) or interval-based (pre-timed) controller. With the various I/O modules, D modules and Communications modules that can be installed into the unit, it can be mated to a variety of cabinet wiring harnesses.

ATC-1000 Advanced Traffic Controller 7

Following the ATC standard, the ATC-1000 uses the Linux operating system internally. It has an engine board attached to the rear of the display and keypad modules. The engine board runs Linux and the traffic engines that determine what outputs will be sent to which connectors, and which inputs will be read at what time. A somewhat unique feature for the ATC-1000 and ATC-2000 controllers is that they have dual traffic software engines, which allows them to be easily switched between NEMA phase-based and pre-timed, interval-based operation. This is accomplished by a simple pattern change. The ATC-1000 can be set to operate in any one of the 255 available intersection traffic patterns. If any pattern between 1 and 48 is chosen, the controller operates in NEMA phase-based mode. If a pattern between 101 and 228 is chosen, the controller operates in pre-timed interval mode. Pattern 255 is Flash. Pattern 254 is Free. Selecting any pattern other than those listed here puts the controller into ‘Backup Free’ operation.

Power is supplied to the controller via the I/O module. The exact pins to use for power depends on which I/O module is installed.

Power Input on TS2 Type 1 I/O Module This I/O module only has a single, small ‘A’ connector, which is primarily used to supply power to the controller. Most of the other communications between the controller and cabinet occur on the controller’s serial connectors. For this type of I/O module, AC Neutral is on pin ‘A’. AC Line voltage (120VAC) is on pin ‘C’. Chassis/Earth Ground is on pin ‘H’.

Power Input on TS2 Type 2 I/O Module There are three connectors on the TS2 Type 2 I/O module, but power is still supplied through the left-most one, labeled ‘A’. For this type of A connector, AC Neutral is on pin ‘U’. AC Line voltage (120VAC) is on pin ‘p’. Chassis/Earth Ground is on pin ‘V’.

Power Input on LMD I/O Module The LMD I/O module has two connectors, A and B, but power is yet again supplied on the ‘A’ connector. For the LMD A connector, AC Line voltage (120VAC) is supplied on pin ‘p’. AC Neutral is on pin ‘U’, and Chassis/Earth Ground is on pin ‘V’

Power Input on HMC-1000 I/O Module The HMC controllers were a line of devices manufactured by Honeywell Corporation in the 1970s and 1980s. They were among the earliest traffic controllers that implemented the NEMA TS1 standard. The HMC-1000 I/O module has 1 connector and a switch. The main connector is labeled connector ‘INPUT/OUTPUT’ and it has AC Line voltage (120VAC) supplied on pin 61. AC Neutral is on pin 62, and Chassis/Earth Ground is on pin 63.

Chapter 1 — Introduction to the ATC-1000

8 ATC-1000 Advanced Traffic Controller

Traffic Engine Peek ATC controllers are unique in that they have two distinct traffic engines, or software applications that cycle an intersection through the desired signal sequences, available at all times. The controller determines which engine to use by which intersection ‘Pattern’ has been requested. Peek ATC controllers can use only one of the available 255 Patterns at any given time. Patterns 1 through 48, along with patterns 254 and 255 are NEMA engine patterns. Patterns 101 through 228 are Interval-based patterns.

NEMA Operation The ATC-1000 will run as a NEMA, phase-based controller as long as a pattern between 1 and 48 has been selected. (Or the special patterns defined by NEMA as Pattern 254: Free operation, and Pattern 255: Flash.) As a NEMA controller, the ATC-1000 configures movements within an intersection based on phases rather than intervals. A phase, by the NEMA standard, is a traffic movement that includes a standard vehicular signal transition cycle defined for every movement in a U.S. or Canadian intersection as: Red --> Green --> Amber --> Red. Within this environment, the ATC-1000 has the following capabilities:

Up to 16 phases of vehicle and pedestrian movement Up to 16 phases in 4 rings Up to 48 coordination patterns Up to 16 split configurations Up to 4 overlap movements Up to 6 preemption plans Up to 64 vehicle detector inputs Up to 8 pedestrian detector inputs Up to 48 Time of Day action plans Up to 32 Time of Day day plans Up to 32 Time of Day schedules The ability to communicate with a Central System via the NTCIP protocol

The ATC-1000 controller uses the US Department of Transportation sponsored and ITE (Institute of Transportation Engineers) written Advanced Transportation Controller standard. The physical connections that are made to the cabinet depend on which I/O and D Modules have been installed in the unit. The controller can be configured to use TS2 Type 1, TS2 Type 2, HMC-1000, or LMD connections. D modules are available in a number of configurations that allow for special customer requirements, including ATC standard, Peek 3000E, LMD, Idaho D, Traconex and Multisonics D modules.

Interval-based Operation The ATC-1000 will run as a pre-timed, interval-based controller as long as a pattern between 101 and 228 is selected. Interval-based operation is used by most of the world

Conventions Used in this Manual

ATC-1000 Advanced Traffic Controller 9

other than the United States and Canada, and even in those two countries, some cities, states, and provinces use the interval-based programming rather than NEMA programming. An interval is defined as a period of time during which all of the signal outputs output by the controller are in a fixed state. Whenever any signal output needs to change, that marks the beginning of a new interval. Interval-based operation can include preemption, TSP operation, and detector actuation to adjust timing.

Transitions Between NEMA and Interval-Based Operation Any time that the controller will be asked to switch between NEMA and Interval-based operation, or vice versa, the controller will manage the interface between the two, very different modes of operation by transitioning into and out of the Red Rest state. Both NEMA and Interval-based operation recognize the Red Rest state, and both have set transition sequences to access and leave Red Rest. Peek ATC controllers utilize this area of commonality to enable a traffic engine transition without the need to send the intersection into a Flash state.

Cabinet Environment The ATC-1000, as long as it is fitted with the proper type of I/O module and firmware, can function as a controller replacement in any cabinet that currently hosts a TS1, TS2 Type 1, TS2 Type 2, HMC-1000, LMD 40, LMD 9200, Traconex, or Multisonics traffic controller.

CONTROLLER HARDWARE

The primary human input and output interface, the digital and serial data ports, as well as the fuses and power indicators, are all part of the ATC-1000 controller’s ‘Main Module’. This is housed in the top left corner of the controller enclosure and is typically never removed from the housing by the traffic technician.

Figure 3 – Front view of the ATC-1000 controller Main Module

Enclosure The ATC-1000 controller uses a modular design; all fuses, connectors, and controls are accessible from the front of the unit, as defined in the Advanced Transportation Controller standard. The top of the ATC-1000 housing is closed and free of any openings, to prevent dirt, dust, water or other debris from entering the top of the unit. Ventilation holes are provided on the rear of the unit. The resulting ventilation is more than enough to cool the electronics. The design is such that foreign debris and water cannot easily enter the case in a typical installation.

The controller is constructed so that it can be shipped easily via common carrier without the need to disassemble the unit.

Operating System, Firmware and Memory When the ATC-1000 controller is powered on, it loads a copy of the Linux operating system from BIOS into flash memory and runs it. The operating system then loads the programming and data the unit needs to operate.

The controller’s basic functionality is defined by its programming. This programming is maintained as data in non-volatile flash memory. Firmware can be stored or updated in the unit in a couple of ways. It can be stored to internal flash memory either from a USB memory chip via the USB port at the front of the unit, or through the PC Ethernet port via an attached Microsoft Windows PC that is running the IQ Link software utility.

The controller’s ‘database’ is its set of operating parameters that tell the software exactly what type of intersection is being controlled. This database can be loaded in three possible ways: via the USB port, via an Ethernet connection to a PC running IQ Link, or via a comms link to a central system software package such as IQ Central.

The ATC-1000 controller’s Linux operating system continuously checks the integrity of the unit’s internal memory, the loaded firmware, and the local database of configured parameters. If the controller detects a fault, it will immediately terminate its watchdog output (i.e. CVM or Fault Monitor) to the CMU or MMU, which will place the cabinet (and the intersection) into FLASH mode. When this situation occurs, the controller’s display shows a message indicating the cause of the failure.

Display The front panel display of the controller is a 40 character wide by 16 row tall LCD screen. The display shows the ATC-1000’s menu system, its currently configured parameters, and status screens that display the current situation within the controller and in the intersection.

The display is fully operable over the temperature range of –4 to +158°F (–20 to +70° C). Below 32°F (0°C) a heater comes on to warm up the display, but only when the cabinet door is open. The display will not be damaged by lower temperatures when the heater is not on, it just won’t display properly.

Contrast Control The liquid crystal display has a user configurable contrast setting. To modify the contrast of the screen, the power to the unit must be on and it must be beyond its initial startup routine. Press and hold the blue function key on the controller’s keypad (located at the bottom right corner of the keypad), then use the contrast up and contrast down keys to change the screen display.

Keypad The ATC-1000 controller includes a two section keypad to the right of the display window. The left part includes 16 keys for alphanumeric entry and selection. The right-side 16 keys provide the functional keys, including the blue ‘Function’ key, the green navigation arrow keys, the Yes, No, and ENT(Enter) buttons, and several other special function keys.

Figure 4 – ATC-1000 keypad

1 to 0 — The numbered keys on the keypad are used to enter values into parameter screens, as well as to choose numbered items in menus. When you are in a set of related screens, such as the six Preemption screens or the eight TSP Run Configuration screens, as long as you are not in Edit mode, you can also press the number of the screen to go there directly. So pressing the 4 button while in the Preemption screens would take you to fourth preemption screen (MAIN MENU > 6 > 1 > 4.)

A to F — These are used to enter values into hexadecimal fields.

E — The E key on the keypad has a second, important function. With the Blue function key ( ), it toggles the controller into and out of database edit mode. When in Edit mode, pressing the -E again

saves any changed values on the screen and returns the controller screens to read-only mode.

HME — Everywhere in the ATC-1000 interface, the HME, or Home button, returns the user to the main status screen, 1.1 Controller Status. This screen can also be accessed by choosing the first option (Controller Status) on the Status menu. (MAIN MENU > 1 > 1)

Arrow Keys — When the controller is in Edit mode, the arrow buttons are used to navigate between parameter fields on controller database screens.

Controller Hardware

ATC-1000 Advanced Traffic Controller 13

UP (+) — When in sections of the database with multiple screens, such as the six screens of Preemption (Main Menu > 6), or the two pages of Vehicle Detector Options (Main Menu > 5 > 1), the Up and Down keys are used to switch between screens. The Up (+) button moves you to the screen closer to the begging of the list (e.g. 2 -> 1, 6->5).

If the Blue function key ( ) is pressed first, the Up button can be used to increase the contrast of the ATC-1000 display.

The Up and Down buttons are also used to switch between the various Status screens. The Controller status screen is at the top of this list, and it follows the order on the Status menu.

HLP — Toggles the help information for the current screen on and off. When in Edit mode, it displays the help information for the currently selected field. The CLR/ESC button can also be used to exit out of a help screen. And when in the Home status screen (aka the Timing Status, or Controller Status screen) the HLP button displays revision and copyright information about the ATC-1000 firmware.

ENT — ENT, or the Enter button, is used in a variety of places in the interface to proceed past warning or error messages, such as when you’ve entered invalid data into a parameter field. It is also used to select a file, value, or test in the Diagnostics screens.

MNU — MNU, or the Menu button, takes you to the Main Menu of the controller, no matter where you are in the interface. Note that this doesn’t work when you are in the Diagnostics menus, or in the Help screens. You must first exit from those environments to use the MNU button to display the Main Menu. If you press the Blue function button ( ) before pressing MNU, it will open the ATC-1000 Utilities menus.

PRV — In the menus, the PRV or Previous button, will move you one step up the menu tree. For instance, if you are in the Time Set screen and you press PRV, it will move you to the Time of Day Menu.

DWN (–) — The UP and Down buttons are used to move between parameter screens for those parameters that have multiple screens of settings, such as Preemptions, Pattern Tables, and many others. The Down button moves you to the screen lower on the list, so 1 -> 2, 5 -> 6, etc. If the Blue function key ( ) is pressed first, the DWN button can be used to decrease the contrast of the ATC-1000 display.

The Up and Down buttons are also used to switch between the various Status screens. The Controller status screen is at the top of this list, and it follows the order on the Status menu.

Chapter 1 — Introduction to the ATC-1000

14 ATC-1000 Advanced Traffic Controller

NXT — NXT or the Next button. Used when entering the Diagnostics mode of the controller, under the Maintenance menu. The NXT button is also used to cycle through preset, non-numeric values for controller settings.

YES/NO — Primarily used to turn parameter settings on and off in the parameter screens of the interface (after entering Edit mode with the -E key combination.) A Yes is indicated in the interface by an ‘X’ next to a setting. These keys are also used for some settings that have a direct ON/OFF screen value, such as DAYLIGHT SAVINGS on the 2.4.7 Time Settings parameter screen.

CLR/ESC — The Clear/Escape key is used to return a field to its default value (usually all zeros for numerical values, or OFF for binary parameters.) This button is also used to exit out of the Utilities menus, and out of the Help screens.

— This is the ‘special function’ key for the controller. Pressing this button before pressing one of the other keys showing a blue label above or around it will command that button’s secondary function. These include opening the Utilities menu (MNU button), changing the controller display contrast (UP+ and DOWN- buttons), and forcing on and off the display backlight (YES button).

Comms and Utility Connectors Just below the keypad on the front panel of the ATC-1000, the controller has four D-sub type serial ports and a USB port. These ports have a variety of uses.

local file transfers

as a connection point to a central system

as a local connection point for the IQ Link utility software

as a connection to the cabinet (for TS2 Type 1 operations)

as a connection point to an external backup power supply monitoring circuit

as a connection point to a conflict monitor

a place to upload controller firmware or a traffic database (via the USB port)

Controller Hardware

ATC-1000 Advanced Traffic Controller 15

Figure 5 – Comms and Utility Ports

The details about each port are described in the next sections, describing the ports from left to right.

USB Port The ATC-1000 controller includes a single USB ports on the front panel. It functions the same way a USB port does on a PC. The port is designed to allow easy transfer of files to and from the controller using small portable memory devices such as USB memory sticks or thumb drives. At present, only passive RAM devices have been tested to work with the controller, so other types of USB devices such as external USB hard drives, mice, keyboards, and cameras will not be recognized by the controller.

The USB port is "hot-swappable" – the controller does not need to be shut down and restarted to attach or remove a USB memory device; simply plug the device into the USB port and the controller automatically detects it and displays a menu of options from which you can select a desired action.

USB device detected – remove to exit >1.USB->DATABASE 4.CMU_LOG->USB 2.DATABASE->USB 5.UPS_LOG->USB 3.LOG->USB

Use the Up and Down arrow buttons to navigate between the menu Options. Press the ENT key to make a selection.

Chapter 1 — Introduction to the ATC-1000

16 ATC-1000 Advanced Traffic Controller

Port 1 - SDLC Port 1 is an RS-485 port (now known as an EIA-485 differential serial communications interface.) This port is used in a TS2 cabinet to communicate with other devices within the cabinet. Typically, TS2 Type 2 controllers use the SDLC port to connect to the intersection MMU.

The 15 pin female port uses the SDLC (synchronous data link) communication protocol with a bit rate of 153.6 Kbps, as required by the NEMA TS2-2008 Standard. This port’s TX LED is on whenever the controller is transmitting data. The RX LED is on whenever the controller receives data on this port.

The port’s high speed full duplex data channels utilize four twisted pairs: two transmit and receive data pairs, and two transmit and receive clock pairs. The pin assignments for Port 1 are detailed on page 322.

Port 2 - Central Port 2, also known as the Central Port, is often used to connect the controller to a central software system such as IQ Central, either via a direct serial connection, or via a modem (e.g. TELCO, fiber optic, or radio modems). This is the standard port used to connect to a central system software package when connecting via direct serial or a modem. The port can be configured in firmware and will support transmission speeds up to 115.2K bps. Port 2, Port 5, and the Ethernet ports are the only ports that fully support the NTCIP protocol.

Standard serial communications are supported with speeds from 1200 bps to 115.2 Kbps, as well as Parity (Odd, Even, None), Stop Bit (1 or 2), and Handshake (None, Xon/Xoff, Hardware) settings.

Port 2’s TX LED goes on whenever the controller is transmitting data and the RX LED goes on whenever the controller is receiving data on the port.

The pin assignments for Port 2 are detailed on page 323.

Port 4 - Local The Local port, or Port 4 on the ATC-1000 Controller is a male 9-pin serial port that is often used to connect a Conflict Monitor (CMU) or Malfunction Monitor (MMU) to the controller. The data rates for this port are firmware-selectable from 1200 bps to 115.2 Kbps. Parity (Odd, Even, None), Stop Bit (1 or 2), and Handshake (None, Xon/Xoff, Hardware) can also be set for this port in the controller firmware. This port is also often used as the connection point to directly attach a PC that is running IQ Link, thus allowing firmware updates and interactive configuration modifications on site.

Just as with Port 1, this port’s TX LED lights whenever the controller is transmitting data, and the RX LED lights whenever the ATC-1000 is receiving data on this port. The pin assignments for Port 4 are detailed on page 325.

Controller Hardware

ATC-1000 Advanced Traffic Controller 17

Port 5 – UPS/Spare Port 5, or the ‘Spare’ port, is a 9 pin male RS-232 port that is typically used to connect a data cable from a cabinet UPS system to the controller, or it can be used to connect a PC directly to the controller via a standard serial cable (for example, to use it with IQ Link.) Port 5 can also be used as a connection point to the central software system.

The TX LED indicates when the controller is transmitting data and the RX LED indicates when it’s receiving data on the port. The pin assignments for Port 5 are detailed on page 326.

Ethernet Ports The ATC-1000 has two RJ-45 Ethernet ports as a standard configuration. However, the ATC-2000 controller can also be ordered with the full complement of four Ethernet ports, as specified in the FHWA ATC standard. The Ethernet ports all use the standard 10Base-T network interface, and conform to the IEEE 802.3 standard for twisted pair communications. The network interface supports transmission at the full 10Mbps rate. Each ATC-1000 controller has a unique MAC network address, which can be viewed in the firmware interface by choosing the Revision screen under the Status menu (MAIN MENU > 1. STATUS > D. REVISIONS). The port supports communications using either TCP/IP, SNMP, or NTCIP networking protocols. The Ethernet connectors and Ports 2 and 5 are the only ports that can be used to connect the ATC-1000 controller to a central server software system such as IQCentral.

Unlike the other ports on the front of the ATC-1000, which indicate Transmit (TX) and Receive (RX) status via their LEDs, the Ethernet ports have built in LEDs that indicate status in a slightly different way. The yellow “LINK” LED indicates that the Ethernet port is connected to an active Ethernet hub/switch or computer (i.e. something outside of the controller has acknowledged that the port is on the network,) and that the controller is ready to transmit and receive data on that network. The green “ACT” LED shows when the Ethernet port is being used to actually transmit and receive data.

Optional Expansion Slot Ports Along the right edge of the unit, the ATC-1000 Controller has a vacant slot available behind a removable front panel. This slot can accommodate either a Peek 2070–6A Asynchronous FSK Modem card or a Peek 2070-7A Asynchronous Serial Communication Module. The connector in the slot is the 96 socket contact DIN 41612 as specified in the CalTrans TEES – 1999 to support a 2X wide board. The serial ports that result from installing either of these cards can be configured in the firmware to support transmission speeds of from 1200 bps up to 115.2 Kbps. The firmware can also be used to set the Parity (Odd, Even, None), Stop Bit (1 or 2), and Handshake (None, Xon/Xoff, Hardware) settings for these ports. The pin assignments for these cards are available in the documentation provided with those optional add-on cards.

Chapter 1 — Introduction to the ATC-1000

18 ATC-1000 Advanced Traffic Controller

Note The 2070 slot in the ATC-1000 can host the above Peek 2070 modules, but it can also host any CalTrans TEES compliant 2070 comms module, no matter the manufacturer. Again, the pin assignments and exact functionality of these third-party modules is defined in their documentation.

Controller Hardware

ATC-1000 Advanced Traffic Controller 19

I/O Module Connectors In the space just below the main display, keypad, and comms connector panel is the location of the ATC-1000 Input/Output (I/O) module. There are four I/O module variants available for the ATC-1000:

TS2 Type I

TS2 Type 2

LMD 40

HMC-1000

The number and type of connectors that you see near the bottom front face of your ATC-1000 controller is determined by which of these four I/O modules are installed in the controller. The type of I/O module installed in the controller determines what type of cabinet the unit can be installed into.

Figure 7 – Example I/O Modules

No matter which type of I/O module is being used, the ATC-1000 will automatically detect the type installed in your controller as soon as it is powered up. A single cable

Chapter 1 — Introduction to the ATC-1000

20 ATC-1000 Advanced Traffic Controller

connects the I/O module to the ATC-1000 motherboard. If a D module is installed in your controller, either one or two connectors may be attached to the back of the I/O module from that unit as well. (D modules are always connected to the ATC-1000 through the I/O module.)

The pin assignments and voltage and current requirements of the various I/O module connectors are defined in “Chapter 13 — I/O Module Connector Details”, starting on page 329.

Heartbeat LED The front panel also includes a “Heartbeat” LED, which flashes at a rate of four times per second as long as the controller’s internal fault monitor signal is being generated and the traffic engine is running. If the controller is powered ON, but has a serious problem, the blinking of this LED will halt completely, meaning that the LED will stay on in an unblinking state.

Data Key Port A Data Key port is part of the FHWA ATC standard and is known as a ‘keyceptical’. This port is available as an option on the ATC-1000 and ATC-2000 controllers. The actual ‘key’ that is used in these ports is a non-volatile computer memory device that can be used to store controller database (i.e. traffic programming) and conflict monitor programming card settings. It functions in much the same way that a USB thumbdrive does when one is inserted into the ATC-1000 USB port, with one additional feature. If the data key has CMU or MMU programming information stored on it, the controller and conflict monitor will interact to verify that the conflict matrix defined therein is valid and compatible.

Figure 8 – Datakey type data receptacle

Compatible data keys are available from DataKey Electronics, Inc. of Minneapolis, Minnesota. (www.datakeyelectronics.com). The ATC-1000 and ATC-2000 can accept SFK series SPI 5V Flash & EEPROM type serial memory keys.

Controller Hardware

ATC-1000 Advanced Traffic Controller 21

Power System The ATC-1000 controller is powered through the I/O Module. The exact port and pins used to provide power to the controller depends on which I/O module is being used, but it is typically the left most port on the module, which is called the “A” connector on the TS2 I/O modules. For instance, on a TS2 Type 2 I/O module, power comes in by accepting 120VAC on pin p and AC neutral on pin U.

There is no internal battery backup for memory storage or the real time clock in the ATC-1000 controller. During power down or power outages, all static memory (SRAM) and the real-time clock are powered by two super capacitors. In the event of an AC power outage, these capacitors provide sufficient power to maintain the SRAM contents and the functioning of the real time clock for up to seven days.

AC power goes to a power module, located behind the front face of the main controller module, along the left side of the controller. The power LEDs and fuses on the front panel of the controller are actually part of the ATC power module.

Fuses The controller is fitted with a pair of easily replaced front panel power fuses. These are located in the lower left corner of the main display/keyboard module.

The bottom fuse is a 1 Amp fuse that protects the internal circuitry of the controller from excess current coming into the unit via main AC power. The top fuse protects the controller from over-current situations occurring on the Fault Monitor output pin of the I/O module connectors. For example, on the TS2 Type 2 I/O module, this output is located on pin A of the MS-A connector. No matter which I/O module is connected, this fuse is designed to blow if the 24VDC output exceeds 1 Amp of current.

Setting Up Daylight Savings Time The ATC-1000 can use daylight savings time (DST) based on fixed dates, certain days of a month, or it can be turned off entirely. By default, DST is deactivated in ATC controllers shipped from the factory. To enable DST, you just need to load the default DST plan, which uses the standard dates for DST that are typical in the United States. Then, it is easy to modify the plan, if so desired, using the Exact Date and Day of Week Occurrances options.

There are more details about the DST settings and the other time and date settings on the ATC controller in the “Time of Day Menu” topic, starting on page 146.

1. Before adjusting your DST settings, please verify that the date and time values for the controller are correct. (Press the HME button to see the standard Status screen, which shows the current date and time.) If these values are not correct, use the steps in the “Setting the Date and Time” procedure on page 22, to set the values correctly.

Entering Edit Mode All of the screens in the ATC-1000 menu environment are displayed in a ‘read-only’ format when first shown. You have the option, however, to change the settings on the controller database screens by entering Edit mode. This is done by navigating to the screen where the desired parameter is stored and then pressing the Blue function button and the E (Edit) button together. An asterisk (‘*’) will appear at the top right corner of the screen after the button has been pressed. The asterisk disappears when a function option, such as E for Edit is pressed. Once in the Edit mode, one of the data fields will flash, indicating which field is the cursor location..

Note Status screens do not have any editable fields. The only exception to this is the Backlight Timeout value on the Miscellaneous Status screen of the Utilities Menu, (See ‘Entering the Utilities Menus” on page 31.)

At this point, you can use the arrow buttons to move around on the screen. The currently selected field is indicated by blinking. Typing in a number or other value will replace the value in the currently highlighted field. The YES and NO buttons are used to toggle binary values, such as ‘Phase Enabled’. After you have changed a value, it will continue blinking until you save the changed values by pressing the -E key combination again. This also takes the ATC-1000 out of Edit mode.

Entering the Menu System By default, when the controller starts up, it will display the 1.1 Timing Status screen. To enter the Main Menu system of the ATC-1000, press the MNU button.

ATC-1000 FIRMWARE

The firmware in the ATC-1000 Controller is a program running in the controller’s Linux operating system environment. It defines the menus and available parameters displayed from the controller’s database. The firmware is the program that applies the controller database values to the operation of the intersection.

Because of it’s importance, and the fact that the ATC-1000 firmware can be updated by customers, we’re providing details on how to check your controller firmware, and instructions on how to update the firmware stored in the controller.

Checking the Current Version of Firmware The operating system and firmware that are currently loaded in the ATC-1000 controller are details on the Revisions screen. To view the data, follow these steps:

1. Power up the unit

2. Press the MNU button to enter the menu system.

3. Selection option 1 for the Status menu.

4. Press the letter D on the keypad to open the Revisions screen. (See Figure 18.)

Updating Firmware Using a USB Thumbdrive Follow these steps to update the firmware within an ATC-1000 controller:

Note The controller’s operating system and boot loader will only accept an update to a firmware version that has a higher version number than that currently stored in the unit. If you wish to return to a previous version of firmware, you will need to contact Peek Traffic Customer Service for assistance.

1. If this is the first time the USB drive will be used for ATC firmware transport, you will need to prepare the drive so that the ATC unit recognizes it. If the drive is not yet formatted, begin by formatting it as a FAT drive using your Windows PC. (Locate the drive in Windows Explorer, right-click on it, and choose ‘Format’.) Note the name and location of the thumbdrive on your system for the next step.

2. Open IQ Link on the Windows system where the thumbdrive is attached. Select the Utils menu and choose Phase 2 > Write USB Files/Folders, as shown in Figure 20.

Figure 20 – Write USB Files/Folders in IQ Link

3. Navigate to the drive letter where the USB drive is connected and click on SAVE. A dialog box will open to acknowledge completion of the task creating the necessary signature file and folders.

Figure 21 – IQ Link creates the drives and files on the thumbdrive

4. Click OK.

5. Open Windows Explorer and navigate to the thumbdrive. You will see the directory structure illustrated in Figure 26.

ATC-1000 Firmware

ATC-1000 Advanced Traffic Controller 35

Figure 22 – Directory on the USB thumbdrive

The ‘Signature File’ that identifies the drive to the ATC controller is called ASTC_DATA_DISK, as shown above.

6. Store the ATC-1000 firmware update file on the USB thumbdrive. Place the file in the \ATC_LINUX\USTC_firmware folder. The file is available from Peek Traffic’s customer support team. The firmware must be newer than the version that is currently stored on the controller, or the controller will not accept it during the update process. A firmware file is named ‘natc_v00#R###.bin’ where the #’s indicate the version and build of the firmware. For instance, the file for version 3.5, build 304 of the firmware is called ‘natc_v005R304.bin’.

7. Now go to the ATC-1000 controller. Go into the System Maintenance area of the controller’s menus and choose the Diagnostics Mode. (MAIN MENU > 3. SYSTEM MAINTENANCE > 3. ENTER DIAGNOSTICS MODE)

Caution The next step will put the controller into Flash mode.

8. Press the NXT button to proceed into Diagnostics Mode.

9. Choose option 7.Update Firmware.

10. The FWLoader utility will start. When you see the following screen, plug the USB thumbdrive containing the new firmware into the controller’s USB port. (The Ethernet addresses that appear on this screen depend on the Ethernet port settings for your particular controller.)

USING THE IQ LINK UTILITY WITH THE ATC-1000

The IQ Link software utility operates under Windows 2000, Windows XP or Windows Vista. This software allows a PC to create a simple connection to the ATC-1000 controller’s firmware using either an Ethernet port or a serial port. Once connected, IQ Link can be used to:

Load updated firmware to a connected controller

Change parameters in a connected controller’s database

Create a firmware update on a USB thumb drive

Create a controller database on a USB thumb drive that can then be loaded to an ATC-1000 in the field

Figure 26 – IQ Link software interface

For details on how to install the utility and how to use it with the ATC-1000 controller, refer to the “IQ Link Operating Manual” which can be retrieved from the Peektraffic.com website (http://www.peektraffic.com/ptmanuals.htm), or it can be ordered as a printed copy by contacting the Sales Department at (941) 845-1253 or via email at sales@peektraffic.com. Request part number 81-1202.

Using an ATC-1000 With IQ Central

ATC-1000 Advanced Traffic Controller 39

USING AN ATC-1000 WITH IQ CENTRAL

IQ Central is Peek Traffic Corporation’s own central traffic management software system. It allows a central PC computer (or network of computers) to connect with, monitor, reprogram, override, and preempt a variety of traffic equipment types. Primarily, IQ Central is used to monitor and access traffic controllers in the field remotely from a central location. IQ Central uses NTCIP as its communications protocol, which is also the standard protocol used by the Peek ATC controllers.

Figure 27 – IQ Central software interface

There is a great deal more information provided on using IQ Central, setting up devices and communications connections, and programming devices using its interfaces, within the IQ Central Operating Manual. However, the basic steps to get your ATC-1000 connected to IQ Central are these:

1. Pick a connection method between the central location and the device: modem, direct serial, Ethernet, radio modem, etc.

2. Configure the ATC-1000 communications to central using the parameters on Comm Ports and IP/Cab setup menu. (MAIN MENU > 2 > 1 > 5).

Chapter 1 — Introduction to the ATC-1000

40 ATC-1000 Advanced Traffic Controller

3. Once there, select option number 2. PORT 2-5 setup parameters. Base your communications parameters on the type of connection being used, and the port through which you plan to communicate with the Central system.

4. In IQ Central, add a new Connection based on the channel type and details (i.e. phone number, IP address).

5. In IQ Central, define a device of the type PEEK ATC.

6. From the selected new device instance in IQ Central, select the Connection you created previously.

7. Test the connection to IQ Central by attempting to retrieve a portion of the device’s database into the Upload/Download module.

Chapter 2 — Quick Start: Getting a Unit Up and Running

This chapter discusses how to get a new ATC-1000 controller operating and describes the basics of installing the unit in an intersection cabinet. The following topics are discussed in detail in this chapter:

• Component checklist, on page 42.

• Setting the IP address, on page 50.

• Loading a default database, on page 52.

• Field deployment, on page 53.

• Programming a basic intersection, on page 54.

Chapter 2 — Quick Start: Getting a Unit Up and Running

42 ATC-1000 Advanced Traffic Controller

OVERVIEW

When the ATC-1000 controller is first sent to customers, it will have firmware, a MAC address, an IP address, and a cabinet address installed. These instructions explain how to configure a brand new unit for use in a traffic cabinet

HARDWARE SETUP CHECKLIST

To operate properly, an ATC-1000 controller must be installed in a traffic cabinet environment that matches the type of hardware and firmware that is installed in the unit. However, before it can be inserted into a cabinet, you should verify that you have the following hardware elements for the controller:

ATC-1000 unit

Proper I/O module (TS2 Type 1, TS2 Type 2, HMC-1000, or LMD 40)

A set of cabinet connectors that match the I/O module connectors. In particular, the power supplied on the pins of the ‘A’ connector must be valid for the I/O module.

Communications hardware to connect the controller to a central system, if one will be connected. This could include serial cables, Ethernet cabling to the cabinet, or an external modem and cables.

A USB data thumb drive for transporting controller firmware and databases to the controller in the field.*

Cabling to connect a conflict monitor or malfunction management unit (MMU)*

Cabling for the data connection of an uninterruptable power supply (UPS) system*

Data key for transferring controller databases or conflict monitor compatibility matrices.*

Serial cable to connect an IQ Link PC to the controller via Port 5, or CAT5 cable to connect to the Ethernet port.

Properly jumpered programming card for the conflict monitor or MMU.

* Optional items. Not strictly required for operation

Software Setup Checklist

ATC-1000 Advanced Traffic Controller 43

SOFTWARE SETUP CHECKLIST

The ATC-1000 also needs several data objects to be installed properly within the controller. Without these elements, the controller will not function in a cabinet, even when properly wired and cabled. These are the data objects:

A unique MAC address (needed for Ethernet communications). The current MAC address for the internal network card is displayed on the Revisions screen (MAIN MENU > 1 > D).

A unique cabinet address. (Used by IQ Link as a controller identifier.)

IQ Link installed on a PC. This PC must have the Windows SNMP Manager service installed in order for IQ Link to function correctly. This service can be installed from your Windows installation disk or CAB files.

An IP address for the controller (needed for Ethernet communications). This can be viewed and edited on the IP/Cabinet Address screen (MAIN MENU > 2 > 1 > 5 > 3). It is labeled as IP Address LOCAL.

If an IP gateway address is needed, this is also available on the IP/Cabinet Address screen (MAIN MENU > 2 > 1 > 5 > 3). It is labeled as IP Address SYSTEM.

A default database installed within the controller. A default database can be loaded into active memory from a stored copy using the System Maintenance menu. (MAIN MENU > 3 > 1). Or, alternatively, you can use the Copy Database commands on the System Maintenance menu to load a database from a memory location, such as a USB key or DataKey, or you can modify the database using a PC connected using IQ Link.

Finally, the proper modifications to the controller’s database to make it work with your intersection’s hardware and to logically service your particular intersection’s phases, ped phases, overlaps, preemption calls, etc.

The topics in this chapter describe how to make sure all of the above components are in place before you take the controller out to install it into its cabinet.

Chapter 2 — Quick Start: Getting a Unit Up and Running

44 ATC-1000 Advanced Traffic Controller

Recording the MAC Address The MAC address is a globally unique identifier assigned to each Ethernet network adapter card. The MAC address has been assigned and set at the Peek factory. The current address is displayed as the bottom line of text on the Revisions screen (MAIN MENU > 1.STATUS > D.REVISIONS.)

Important If the MAC address is not present (or set to all zeros ’00-00-00-

00-00-00’), you will need to return the unit to Peek Traffic, so that a valid MAC address can be installed.

Write down the MAC address for the controller and associate it with the location and IP address you will be assigning to this unit.

Setting the Cabinet Address The firmware of the ATC-1000 controller had its start in the Peek IQ ASTC Central Business District controller, also known as the CBD controller. The CBD controller has a very specific requirement for a ‘cabinet address’. At power on, or controller reset, the CBD controller automatically reads the cabinet address. If the controller’s internal cabinet address does not match the address provided by the address circuit in the cabinet itself, the controller and the MMU will place the intersection into Flash.

This check of the cabinet address is not a NEMA function, so it is not done as part of the ATC-1000 controller’s startup. However, the cabinet address is used by the IQ Link software to identify each controller to which it is communicating. The current value of the cabinet address stored in the ATC-1000 controller is displayed as the last four characters on the second row of the standard Controller Timing Status screen. The cabinet address can also be seen, and edited, on the IP/Cabinet Address setup screen (MAIN MENU > 2 > 1 > 5 > 3).

1. Power on the controller.

2. Navigate to the IP/Cabinet Address Setup screen. (MAIN MENU > 2 > 1 > 5 > 3)

2.1.5.3 IP/CAB ADDR SETUP Cabinet Address: 3CC6 IP Address SYSTEM: 128.002.060.198 IP Address LOCAL : 010.247.001.002

Figure 28 – IP/Cabinet Address Setup screen

Software Setup Checklist

ATC-1000 Advanced Traffic Controller 45

3. Press the function key and then the E button (‘Edit’). This places the controller into Edit mode. You can see when you are in Edit mode by the ‘*’ that appears in the top right corner of the screen, and the fact that one of the data fields on the screen begins flashing between it’s current value and a set of asterisks. For instance, the Cabinet address field will start flashing between “- - - -” and “* * * *” to show that this is the currently selected field.

4. Press the green down arrow to go to the IP Address SYSTEM field. Use the number and arrow keys on the controller to enter the new SYSTEM IP address. The last two octets of the SYSTEM IP address, converted to hexadecimal representation, will automatically update the cabinet address field.

5. While still on this screen, write down this value next to the MAC address for this controller that you noted earlier.

Note For ATC CBD controllers in the ASTC cabinet setting, the cabinet address is used to indicate the first two octets of the IP address. For instance, a value of FFFF would indicate that the first two numbers of the IP address are 255.255. This is not the case for ATC-1000 controllers.

6. Once you’ve set the SYSTEM IP address, press the -E combination to save the value and exit Edit mode.

This completes the change of the controller’s System IP and cabinet addresses.

Configuring the SNMP Manager on the PC The next step in getting the ATC-1000 controller running is to make sure that the PC where IQ Link will be running has the SNMP Management service activated. To accomplish these steps, you will need to have Administrative access to the computer, and either the Windows installation CDs or the .cab files of the Windows installation.

Note IQ Link is not strictly required in order to set up and operate the ATC-1000 controller. Unlike the ATC-1000, the ATC CBD controllers are not programmable from the front interface, so IQ Link is required for their setup. In contrast, the ATC-1000 and ATC-2000 can be programmed entirely from the front panel. However, programming and maintaining a network of ATC-1000 controllers can be done more easily and conveniently when used with the IQ Link and IQ Central software tools.

1. Check to see whether the PC already has the SNMP service configured. The easiest way is by a right click on MY COMPUTER and choose MANAGE.

Chapter 2 — Quick Start: Getting a Unit Up and Running

9. At this point, the PC will request the Windows installation disk required for the SNMP files. Insert the disk, or point the installer at the local copies of your Windows installation .cab files.

10. Complete the installation following the onscreen instructions.

11. Go to the START MENU and open the SETTINGS list. Then choose the CONTROL PANEL.

12. Under ADMINISTRATIVE TOOLS, choose SERVICES

13. Scroll down and right mouse click on SNMP SERVICE.

14. Select PROPERTIES.

15. Select the SECURITY tab.

16. Make sure “public” is in the Community field with READ CREATE in the corresponding rights field. If not, then edit the existing field or add a new one. The Community name is case sensitive, be sure to use the lower-case “public” and not “PUBLIC” or “Public”.

This completes the installation and configuration of the SNMP service. IQ Link will not function properly when the PC is connected to the controller without this service.

Chapter 2 — Quick Start: Getting a Unit Up and Running

50 ATC-1000 Advanced Traffic Controller

Setting the IP Address and Ethernet Settings This procedure is intended to guide the user through the process of setting the ATC-1000 controller IP address, which will then allow the user to connect IQ Link to the controller over the controller’s Ethernet ports. This is also an important step if you plan to attach the controller to the central system via the Ethernet ports.

1. Power on the controller.

2. Navigate to the IP/Cabinet Address Setup screen. (MAIN MENU > 2 > 1 > 5 > 3)

2.1.5.3 IP/CAB ADDR SETUP Cabinet Address: 3CC6 IP Address SYSTEM: 128.002.060.198 IP Address LOCAL : 010.247.001.002

Figure 36 – IP/Cabinet Address Setup screen

3. Press the function key and then the E button (‘Edit’). This places the controller into Edit mode. You can see when you are in Edit mode by the ‘E’ that appears in the top right corner of the screen, and the fact that one of the data fields on the screen begins flashing between it’s current value and a set of asterisks. For instance, the Cabinet address field will start flashing between “- - - -” and “* * * *” to show that this is the currently selected field.

4. Use the down arrow key to move the flashing indicator to the first group of numbers in the IP Address Local field.

5. Use the controller’s number keypad to enter the first group. This is a decimal number representing a two digit hex value, so any value between 000 and 255 is acceptable.

6. Use the number keys on the controller to enter the IP system address. This can be any value between 000 and 255, per octet. It needs to be a unique value as far as your copy of IQ Link is concerned. Write down this value next to the MAC address for this controller that you noted earlier.

Note For ATC CBD controllers in the ASTC cabinet setting, the cabinet address is used to indicate the first two octets of the IP address. For instance, a value of FFFF would indicate that the first two numbers of the IP address are 255.255. This is not the case for ATC-1000 controllers.

Software Setup Checklist

ATC-1000 Advanced Traffic Controller 51

7. If your network environment requires it, set the Default Gateway IP address, Subnet Mask, and DHCP Server address on this screen as well.

8. When you are finished editing values on this screen, press the -E key combination to save the changes. If you inadvertently entered an invalid value, such as an IP address octet that is outside the range 000 to 255, then the ATC-1000 will warn you that the value is incorrect and prompt you to return to the screen to enter a correct value number.

That completes the programming of Ethernet/IP settings on the ATC-1000.

Chapter 2 — Quick Start: Getting a Unit Up and Running

52 ATC-1000 Advanced Traffic Controller

Loading a Default Database Into the Controller The process of loading a default database into the ATC-1000 controller couldn’t be simpler. The controller stores default databases internally as a backup system. To load one of the two available default databases into the controller’s active memory, follow these steps.

1. Power up the ATC-1000.

2. Navigate to the System Maintenance menu, and then select Default Database Load (MAIN MENU > 3 > 1)

3. Select whether you would like to install a simple 8 phase, dual ring configuration (option 1), or an 8 phase, dual ring with coordination and preemption settings configuration. (option 2). The controller will load the database from memory and transition over to the new operation automatically.

Field Deployment

ATC-1000 Advanced Traffic Controller 53

FIELD DEPLOYMENT

Because of the large number of I/O options, central comms options, and operating parameters of the ATC-1000, the exact method to install the controller into one of your field cabinets is highly dependent on your local procedures and technical requirements. The basic process to install the controller in the field follows these steps:

1. (Optional) Power up the unit in the office, connecting it to a PC running IQ Link and program the controller with the intersection-specific database settings it needs.

2. Or, alternatively, you could load the programming onto the controller by plugging in a USB thumbdrive containing the database and powering up the unit. Load the database using the USB menu, which will appear automatically.

3. Ensure that all circuit breakers in the cabinet power distribution panel are off. Ensure that the input power is connected to the cabinet power panel and the appropriate buss bar. The cabinet must be wired properly for the intersection.

4. Ensure that all Signal light connections and detector input connections are properly made in the cabinet, including any necessary pedestrian inputs.

5. Place the controller onto a shelf in the cabinet.

6. Plug in the cabinet connectors to the I/O module of the ATC-1000. This could be from one to four cables, depending on the type of I/O module and cabinet you are using.

7. If you are using a TS2 Type 1 I/O module, Connect the SDLC communication cable from the cabinet’s MMU panel to the controller’s Port 1 connector. Ensure that the connector clips on the communication cable properly latches on to the locking blocks. If the MMU has not already been set up for this installation, program or jumper the appropriate co-phases on the MMU’s programming card. Reinsert the programming card into the MMU.

8. Turn on all circuit breakers in the cabinet. For normal three-color operation, check that the SIGNAL AUTO/FLASH switch of the cabinet is in the AUTO position and that the SIGNAL ON/OFF switch is in the ON position.

9. Verify that the ATC-1000 powers on and shows all six front panel power LEDs glowing green. Verify that the power up sequence clears successfully and the unit immediately shows the 1.1 Timing Status screen. Verify that the Heartbeat LED is flashing steadily at approximately 4 flashes per second.

10. Observe the operation of the intersection signals and detection inputs to verify that the intersection is operating as expected.

This completes the general field deployment process.

54 ATC-1000 Advanced Traffic Controller

PROGRAMMING A BASIC INTERSECTION

Because of the numerous operating modes and options on a modern ATC controller, the programming of the controller can be a complex process. These are the basic steps for setting up the parameters to run a normal intersection. These parameters can be programmed into IQ Link or IQ Central without having the controller connected, then once the parameters are double checked and verified, these can be loaded to the controller either over a Central-Local connection (for IQ Central), or via a USB thumb drive transfer or serial connection from IQ Link.

Or you can bypass all that and simply program the controller from the front panel using the keypad.

1. Load a Default Database that is similar to yours. (MAIN MENU > 3 > 1)

2. Define which phases are enabled. (Main Menu > 2 > 2 > 1)

3. Define how the controller should start up operating the intersection from a power off situation. (MAIN MENU > 2 > 1 > 1)

4. Setup the Flash mode you’d like to use for the intersection (MAIN MENU > 2 > 1 > 2)

5. Set the Green times for each phase (MAIN MENU > 2 > 2 > 2)

6. Set the Clearance times (Yellow and Red) for each phase (MAIN MENU > 2 > 2 > 3)

7. Set the Pedestrian times (Walk and Ped Clearance) for each Ped phase (MAIN MENU > 2 > 2 > 4)

8. Set up the vehicle detectors and link them to phases (MAIN MENU > 2 > 5 > 1)

9. Set up pedestrian detectors and link them to Ped phases (MAIN MENU > 2 > 5 > 5)

These are the basic settings for the intersection. There are featured capabilities that can be configured using the rest of the ATC-1000 programming screens (or alternately, using IQ Link or IQ Central as a programming interface.)

OVERVIEW

When the ATC-1000 Controller is powered on, it will go through a startup sequence. After it displays its splash screen, showing the Peek Traffic logo and some information about the firmware, the screen then shows the standard Controller Status screen. The controller’s menu system can be accessed using the Main Menu button (MNU).

Status screens cannot be edited.

For more details about how to navigate around in the menu system, see the next topic.

NAVIGATING IN THE ENVIRONMENT

To navigate around in the ATC-1000 Controller’s menu system requires a few, consistent set of keys. These are the rules:

To switch from the Controller Status screen to the Main Menu, just press the MAIN MENU button.

To switch to the Main Menu from anywhere in the menu system, press the MAIN MENU button.

To switch from any menu back to the Controller status screen, just press HME (Home).

To select an item on a menu, press the number corresponding to that item in the menu.

To move upward in the menus structure, press the PREV MENU button.

When in parameter screens with multiple pages, using the PAGE UP and PAGE DOWN screens to change between the pages. Use the PREV MENU button to exit from the parameter screens. Some parameter screens have two dimensions of screens (e.g. TSP Run Configuration Screens: Configurations 1 through 8, and Runs 1 through 8.) The first dimension is selected using Page Up and Page Down, the second dimension is selected using the numbered keys on the keypad.

FIRMWARE FLOW CHART

The following chart provides an overview of the basic theory on how the ATC controller selects the traffic pattern to use in the intersection.

Figure 37 – Firmware flowchart

Firmware Flow Chart

ATC-1000 Advanced Traffic Controller 59

After going though its startup tests and startup flash routine, it enters a loop in which it checks to see if there is an external or override pattern set, if not, then it looks for a valid pattern for the current date and time, and if there is no valid pattern, it falls back on its default settings for use in Free run mode. If there is at this point not a valid free run pattern defined, it will run the soft flash pattern, or absent even that last fallback position, go to a hard flash mode.

Top-Down View of the Menu System There are several on screen menu systems available from the front panel of the ATC-1000 controller. Pressing the button and the MNU (Utilities) buttons together will open the ATC TS2 Utilities Menu system, as shown in Figure 38.

ENTERING THE MENU SYSTEM

There are three kinds of screens in the ATC-1000 Controller’s menu system: menu screens, status screens, and parameter screens. Menu screens are used to navigate between screens. Status screens show information about the controller and the program running within the controller that cannot be edited directly. Parameter screens show the settings that are stored in the controller and used to run the intersection. The values on parameter screens can be changed using the keyboard and LCD display interface, if one first switches to Edit Mode. The top screens of the whole system, however, are the Main Menu screen and the Timing status screen.

OVERVIEW OF THE STATUS SCREENS

The ATC-1000 controller has fourteen status screens in twelve areas, each of which shows a particular set of critical data on a single screen of information.

Status Menu The contents of the Status menu are slightly different than the other commands and screens described in this menu system: they are the results of the controller’s operation rather than inputs into the controller. The status screens are described in more detail in the next section. (MAIN MENU > 1. STATUS)

1 STATUS MENU 1. controller 8. SDLC & FIO STATUS 2. INPUTS 9. ALARMS 3. OUTPUTS 0. OVERLAPS 4. COORDINATION A. MMU 5. TIME OF DAY B. T.S.P 6. PREEMPTION C. ABS ZERO 7. DETECTORS D. REVISIONS

Figure 42 – Status Options available on the ATC-1000 Controller

Navigating the Status Screens After one has accessed any of the individual Status screens, these are the navigation options:

UP+ button – Go to the next higher status screen. Think of the status screens as a vertical stack of displays, with the 1.1 Controller Status screen at the top of the stack, and the 1.D Revision Information screen at the bottom.

DWN– button – Go to the next lower status screen.

MNU – Return to the Main Menu of the menu system

HME – Return to the top of the Status display stack, to the 1.1 Controller Status screen

PRV – Go back to the previous screen you just visited.

Controller Status Screen

ATC-1000 Advanced Traffic Controller 65

CONTROLLER STATUS SCREEN

The Controller Status screen (or the ‘Runtime Status Screen’) is the default display whenever the controller is running.

(MAIN MENU > 1. STATUS > 1.CONTROLLER) or, you can always call up this status screen by pressing the HME button.

Unlike the other Status screens, which will return to the Status menu when you select PRV, the Controller Status screen does not respond to PRV. Instead, you need to press the MNU button to return to the Menu system. This is a result of this screen being the default status screen for the controller.

Below is a sample of the main run time Status. Beginning on the top left of the display we see the number ‘1.1’. All of the screens in the ATC-1000 show the screen number from the Menu Structure. From the Main Menu, ‘1’ is Status, and the first Status screen is #1 or Screen 1.1 – After the screen number, we see the I/O type is shown as ‘TS21’ which represents TS2 type 1. Next is the Day of the Week, ‘Thu’ short for Thursday, next is the Day of the Month, Month, and Year and a ‘.’ to indicate that DST (Daylight Savings Time) is active. ‘10-Sep-2009.’ – Following the date, is the Port 1 status indicator ‘P1:OK’ (or ‘Err’ if there is a problem). P1:OK is the Port 1 SDLC Communications status for a TS2/Type 1 ATC, but in a TS2/Type 2 ATC, the P1:OK message indicates the communications status between the front panel/engine board module and whatever I/O board is installed in the ATC. See page 77, ‘SDLC & FIO Status Screens’ for more details.

Figure 43 – Sample Controller Status screen – Phase Pattern

The second line from the top is the static text ‘TIMING STATUS’ and the clock in HH:MM:SS (24 hour time) ‘16:51:20’. The four letter string at the end of line 2 (‘00F7’ in this case) is the cabinet address for this controller. The cabinet address is the 2 lower octets of the controller’s IP address, displayed in HEX. In this example, the controllers IP address is 192.168.0.247 so the lower 2 octets are shown as ‘00F7’.

Chapter 4 — Status Displays

66 ATC-1000 Advanced Traffic Controller

The center of the screen shows the timing status of all 4 rings. Both vehicle and pedestrian timers are shown.

On the right side of the screen, to the right of the R1 and R2 indicators, the two PRE lines indicate the current activity on the 6 NEMA Preempt runs. If a Preempt input is active (grounded), the run number will appear to the right. PRE KBD indicates that a manual call has been placed for preemption from the front panel of this controller. This is done from the Preemption Status screen (MAIN MENU > 1.STATUS > 6.PREEMPTION) That is also the only place where this kind of preemption call can be cleared.

Call Status for all 16 vehicle and pedestrian phases as well as the ‘N’ next decision phases complete the left side of the display. In this example there are vehicle calls on phases 1, 3 and 7 as well as ped demand on phases 2, 4, 6 and 8. Pattern selection/hierarchy is shown as follows: CRD CMD:254 (Coord Operational Mode 0-255)

SYS CMD: 6 (System Pattern Control 0-255)

TOD CMD: 11 (TOD scheduler pattern)

NTCIP supports 255 patterns. In the Peek ATC-1000, patterns 1-48 are the NEMA actuated patterns. Each pattern consists of a cycle (between 30-255 seconds), an offset (between 0-254 seconds) and a split table number. There are 16 split tables supported by the ATC-1000. Pattern numbers 101-228 are used to call an Interval based timing/signal plan. The ATC-1000 supports 24 Interval based timing plans and each timing plan supports 4 signal plans. There are 2 patterns that are dedicated to specific functionality. Pattern 254 = FREE operation and Pattern 255 = AUTO FLASH operation.

The pattern selection using NTCIP has 3 layers. The bottom of the plan selection hierarchy layer is the NTCIP TOD scheduler. The scheduler calls ‘Action’ items at HH:MM change points and the action item points to a pattern from 1-255. The TOD scheduler can be overridden by the next layer up in the hierarchy, the System Pattern Control. This object can call any of the 1-255 patterns. When a set of the System Pattern Control object is performed by the central management station, the controller loads the unit backup timer from the database. The unit backup timer can hold a value between 0 and 65, 535 seconds. The System Pattern Control can then be overridden by the Coord Operational Mode object. Unlike the System Pattern Control, the Coord Operational Mode is not loading the unit backup timer. In the example above we see that the TOD scheduler is calling for pattern #11, the System Pattern Control is calling for 6 and the Coord Operational Mode is picking pattern 254 (FREE). So regardless of the NTCIP TOD scheduler or the System Pattern Control values, the controller will run the Coord Operational Mode pattern 254.

The coordination command (CRD CMD:), system command (SYS CMD:), and TOD command (TOD CMD:) messages can be followed by lower-case letter codes. The following table indicates their meaning:

Controller Status Screen

Code Meaning f Coordination has an error, causing it to run FREE

t Coordination is in transition, or offset seeking

s Coordination is in synchronization (i.e. is running correctly)

Pretimed Version of Controller Status Screen If you are running a pretimed pattern (pattern numbers 101 to 228) then the controller status screen shows a different set of information.

Figure 51 – Sample Time of Day Status Screen

This screen is helpful in determining if the ATC-1000 is tracking the TOD schedule correctly. In addition to the Time functions, this display shows each time the coordinator passes over the ‘Local Cycle Zero’ point in the cycle.

Day Plan Status — The number of the Day Plan currently in effect.

Action Number — The TOD Action within the current Day Plan that is currently in effect.

Current Control Plan — The pattern number currently running in the controller. Note that this pattern could be the result of the Time of Day schedule, coordinated operational mode, a central override, or central system control.

If any of the objects under the backup timer have been set, the NTCIP Backup Timer will shown the current value as it is decremented (in tenths of a second).

The current TSP Action plan is displayed in the bottom four rows, along with the current status of the Auxiliary and Special Function outputs that are under TOD control.

Commanded Action Mask – The Time of Day programming screens allow the operator to set up eight ‘commanded actions’, which are all TOD Override commands assigned to that command action number. An X in these slots on the Time of Day Status screen indicates if any of the eight TOD commanded actions are being requested at the current time.

CRC is a method to check that the data sent is the same as the data received by encoding a piece of data within a packet that is dependent on the contents of the rest of the packet. A CRC error tells the device to request a retransmission of the data packet until it is received without such an error. A high count in this field indicates that the transmission line is ‘noisy’, which could indicate interference or a mechanical problem with the wire or connectors.

The rows show communications statistics for the four Terminal and Facility BIUs, the four Detector rack BIUs, and one row for communications with the MMU data. This data is cleared on power up. The columns show the numbers of transmissions (T), packets received (R), NO responses (N), and then errors on transmitted(t) or received(r) packets.

Error counts on each BIU communications line: T = Transmit R = Received N = Not Acknowledged (NAK)

ALARMS STATUS SCREENS

There are two Alarm Status screens, available from the Alarm Status menu.

(MAIN MENU > 1.STATUS > 9.ALARMS)

1.9 ALARM STATUS MENU 1. UNIT ALARM STATUS 1 & 2 2. SHORT ALARM STATUS

Figure 55 – Alarms/Event Status Menu

Option 1 will display the first of the Alarm Status displays.

1.9.1 ALARM STATUS 1 & 2 STOP TIME...... EXT START...... RESPONSE FAULT. POWER RESTART..X COORD ACTIVE... LOCAL FREE.....X LOCAL FLASH.... COORD FAIL..... CYCLE FAULT.... COORD FAULT....

Figure 56 – Alarm Status display

This screen shows the status of NTCIP Status data objects (These are called ‘unit Alarm Status 1’ and ‘unit Alarm Status 2’ in the controller database and in standard NTCIP data structures.) An ‘X’ next to one of these binary data objects indicates that that alarm has been triggered at some point. Most are cleared as soon as the alarm condition ends, however some items ‘latch’, or remain on until some event clears them. The Power Restart bit will stay active until a read from the central system takes place. The Response Fault bit is triggered by a NEMA TS2 Port 1 fault.

Option 2 will display the Short Alarm Status display, as shown in Figure 57.

Figure 57 – Short Alarm Status screen

This screen represents the data stored in the NTCIP database object called ‘short Alarm Status’. Often, central system software polls the controller for this data on a second-by-second basis.

Critical Alarm — This is raised as a result of the Stop Time input going HIGH

NON-Critical Alarm — This is the Cabinet Door switch

Detector Fault – One or more detectors have been found to be ‘faulty’ by the detector input diagnostics. (Refer to page 165 for details.)

Local Override — MCE (Manual Control Enabled) active

Local Cycle Zero — This bit is set each time the controller passes the top of a new cycle

T and F Flash – Terminals and Facilities flash mode

Preempt – The controller has received a preemption input and is currently serving a preemption run

Red Fail – Red Fail flag. No red signal visible in preset amount of time. One or more channels has no indications at all above the required signal thresholds. DIAGF – Diagnostic failure. A software diag failure indicates the unit has failed its program-based diagnostics. A hardware diag failure indicates that the controller is not toggling the watchdog circuit. MINC – Multiple indications failure. This is a result of more than one signal being ON within the same channel, e.g. both yellow and red are being displayed on channel 2. P1TO – Port 1 Type 0 failure. In certain modes, the MMU must be in constant communications with the controller. If the MMU does not receive a Type 0 command frame from the controller within 300 milliseconds, a Port 1 failure will be declared O RELAY – Output relay fault indicates that this relay is de-energized, which could indicate that the MMU has lost power, or the MMU has placed the cabinet in flash mode. RESP TO FAIL – An ‘X’ next to this message indicates that the CMU/MMU responded immediately to a detected fault. STARTUP CALL – The MMU has commanded the controller to restart, by sending the ‘Startup Call’ bit for two or more consecutive messages. LOCAL FLASH – The monitor’s local flash switch has been turned ON. This is usually the input used for a ‘Police Flash’ button or keyswitch n the intersection cabinet. The second screen of MMU status information is currently blank.

Start-Up Configuration Screen The parameters on this screen determine how the ATC-1000 Controller will operate whenever power is restored to the unit after a long outage (meaning, longer than a few seconds in duration.) (MAIN MENU > 2. PROGRAMMING > 1. UNIT CONFIGURATION > 1. START-UP)

2.1.1 START-UP MENU PG1OF1 MIN FLASH...............000 AUTO PEDCLEAR(ON/OFF)...ON BACK-UP TIME..........00000 RED REVERT.............00.0 1 1 1 1 1 1 1 START-UP 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 GREEN X X WALK X X YELLOW RED

Figure 67 – Start-Up Screen

Min Flash – The number of seconds after power-up that the unit should stay in Flash mode before initiating normal phased service operations. This can be any integer value from 0 to 255 seconds. The default value is 10 seconds.

Auto PedClear (ON/OFF) – This parameter determines how pedestrian movement signals (e.g. Walk/Flashing Walk/Don’t Walk) operate after a local override by an official at the cabinet, such as a police officer, occurs. Such an action taken by an official is known as an MCE, or a Manual Control Enable event. When this parameter is OFF, then the override takes immediate effect, even if the pedestrian WALK signal is not finished timing. If this parameter is ON, then these pedestrian movements are cleared as normally defined and the override is temporarily delayed. The default value is ON.

Back-Up Time – This is the value of the backup timer, in seconds. If the controller is operating in an environment where it is being told to use a particular traffic pattern by a central computer or a central coordinating controller (i.e. ‘Traffic Responsive’ operation,) it will expect to receive an NTCIP ‘Set’ command across its communications ports at regular intervals. If the controller fails to hear a Set command for one of these ‘system control parameters’ within the backup time period, the controller will revert to it’s backup plan, i.e. it will start running whatever is its default pattern.

Red Revert – This global setting determines how short a red signal can be under any circumstances in this controller. So, say that an override or a preemption comes in that tells a particular traffic movement to go green. But that movement has just turned yellow. The Red Revert time, which is a value in tenths of seconds between 0.0 and 25.5 seconds, tells the controller to show a red signal of at least that long before switching to the new pattern.

Chapter 5 — Programming Menus

92 ATC-1000 Advanced Traffic Controller

Start-Up (Green/Walk/Yellow/Red) Settings – This table of settings allows the user to define what signals will be displayed for each phase when the controller exits the start-up Min Flash period. After the controller remains in Flash for the required amount of time, these settings serve as the initial state of all of the intersection’s phases. Once these phase signal states are in place, normal operation of the intersection can begin. It is important to remember to follow safety rules when setting these phase states. The controller will not allow an unsafe initial condition to be entered, but it does not monitor these inputs as you enter them. It merely checks to see if the whole table is valid when you use the -E key combination to commit the changes to the controller’s database. If any invalid phase settings exist, for example if you’ve set more than one color for a phase, you will see an error screen and be required to make changes. The error message does not indicate ALL of the problems with the table, merely the first one that was discovered.

ATC-1000 Advanced Traffic Controller 93

Program Flash Screen This screen is used to define how Flash mode functions within the intersection when used as a pattern in Time of Day (TOD) programming. This is also known as MUTCD Flash. (The MUTCD is the Manual on Uniform Traffic Control Devices, written by and maintained by the U.S. Federal Highway Administration. The MUTCD is the oldest baseline source for the definition of how in-road flashing beacons should function in the United States.)

MUTCD Flash, unlike the police-activated flash mode, is created by flash signals created within the controller itself. The other flash modes used by NEMA controllers are merely triggered by the controller; in those other cases, the flash signals themselves are actually generated by the cabinet’s flash transfer relays. By generating its own flash signals during MUTCD Flash mode, the controller maintains direct control of the intersection, and can therefore switch back to normal operation on a time-of-day basis. (MAIN MENU > 2. PROGRAMMING > 1. UNIT CONFIGURATION > 2.PROGRAM FLASH)

Figure 68 – MUTCD Flash Screen

Note MUTCD Flash is Pattern 255 when used in the TOD screens.

Enter MUTCD Flash – This array of on/off values define which phases will first be served with a green, before switching the intersection to all red and then into MUTCD Flash mode. (Note: The values shown in Figure 68 is not a valid setting for an intersection.)

Exit MUTCD Flash – Similar to the Enter MUTCD Flash settings, this array of on/off values determines which phases will be served with green first upon leaving MUTCD Flash mode, before the controller switches to the next programmed TOD pattern. (Note: The values shown in Figure 68 is not a valid setting for an intersection.)

Yellow Flash Channel – This array of 16 on/off values defines which phases will flash yellow during MUTCD Flash operation. The same phase cannot be flashed in both red and yellow.

Chapter 5 — Programming Menus

94 ATC-1000 Advanced Traffic Controller

Red Flash Channel – This array of 16 on/off values defines which phases will flash red during MUTCD Flash operation. The same phase cannot be flashed in both red and yellow.

Alt Half Hz Channel – This array of 16 on/off values defines which phases will flash on an alternating time cycle. A normal MUTCD flash signal is a 1 second cycle with a 50% duty cycle, meaning the signal will be on for a half second, and then off for a half second. Normally, the controller flashes all phases set to yellow and red flash on the same cycle. This option tells the selected phases to flash in the opposite schedule. Sometimes known as ‘Wig-Wag’ flash operation, this tells the controller to flash the phases that are set to Alternate Half Herz ON, when the other flash signals are OFF.

Minimum Flash Time(Sec) – This is the minimum amount of time, in seconds, that the controller must stay in the MUTCD flash pattern before it can be switched away to another pattern. The range of values is from 0 to 255 seconds.

Flash Exit Yellow Time (Sec) – This is the amount of time, in seconds, that all Exit phases are placed into a steady yellow state, before the controller switches to the next programmed TOD pattern. The range of values is from 0 to 255 seconds.

Flash Exit Red Time (Sec) – This is the amount of time, in seconds, that all phases are placed into a steady red state, before the controller switches to the next programmed TOD pattern. The range of values is from 0 to 255 seconds.

Channels Screens In a TS2 Type 2 cabinet, channels are used only to communicate with the MMU unit. The top 2/3rds of this screen are used to define what phases and/or overlaps are assigned to which output channels. There are 16 channels available, eight on the first page and eight more on the second. The numbers on the fifth row of this screen indicate which vehicle phase (1 through 16), pedestrian phase (1 through 16), or overlap (A through D) are assigned to each channel.

Figure 74 – Port 1 Setup Screen

In a TS2/2 cabinet, there are usually no BIUs used, so Port 1 is typically used to connect the controller to the MMU. So, the MMU ENABLE option is normally OFF for the ATC-1000 controller. But if BIUs will be used with the controller, one should enable the MMU on this port and define which BIUs will be used for which Terminals and Facilities connection, and which BIU will be used by each detector rack.

Frame 40 Enable (1 through 16) – NEMA defines several ‘pages’ of data that should be transmitted to and from BIUs for the ‘Poll for Service’ function, . These blocks of data are known as ‘frames’. This function is also known as ‘Secondary-to-Secondary Enable’. Frames that are sent from the controller to the BIU are known as ‘Command Frames’. Command Frame 40 is used to poll secondary stations (what the NEMA standard calls the BIUs in this context) for BIU to BIU communications. These settings tell the ATC-1000 that the Frame 40 message should be sent to the designated BIU (BIUs #1 through #16.) If the BIU has a message to respond to this Frame 40 message, it sends a type 169 frame. If the BIU has no message to send, it responds with a type 168 frame. (Refer to NEMA TS2-2003 Standard document, Section 3.3.1.4.1.15.)

Figure 75 – Ports 2 through 5 Setup Screen

The Parity, Stop Bits, Handshaking mode, and Baud Rate settings for each of the ports are defined in the columns below the port numbers. Baud rate is set by entering a one-digit number in the Baud Rate row of the port’s column, using the values shown to the right in the Baud Rate key.

HDLC Group Address – The HDLC address is the physical network address for an NTCIP device on a network. This is similar to the “Intersection ID” number for TS 1 and non-NTCIP TS 2 units. The HDLC Group Address is used if Central needs to send a “broadcast” message to more than one controller at a time. Group addresses range from 1 to 8191, although address 63 is reserved as an “all stations address.” A group address 63 message will always be transmitted as a single byte with all bits set. A message received with a Group Address of 63 will force the controller to respond, regardless of its actual Group Address setting. If the controller’s Physical Address is set to 63, then the controller will accept any incoming message regardless of how it is addressed. However, this is typically used for testing purposes and should not be implemented in an active intersection as communication “collisions” are likely to occur.

Figure 76 – IP/CAB Address setup screen

Cabinet Address – The cabinet address is typically used only in systems where there is a unique cabinet address module in the traffic cabinet. The controller and this module must talk back and forth to manage the controller cabinet. This is the New York style of cabinet/controller logistics. Otherwise, the Cabinet Address is not used within the controller, or for any other types of cabinet setup. This is a four digit hexadecimal number that can be typed in using the hex keypad on the front of the controller.

IP Address SYSTEM – This is where you can set the IP Address for the ‘System’ Ethernet port. This port is typically used to connect the controller to your central system, such as IQ Central or TranSuite. This is the port on which to connect if you wish to send and receive NTCIP communications.

IP Address LOCAL – This is where you can set the IP address for the ‘Local’ Ethernet port on the controller. This port is often used to connect a laptop while next to the cabinet, for use with IQ Link, or for a telnet or SSH connection to the device.

ATC-1000 Advanced Traffic Controller 101

I/O Mapping Menu Each of the four available I/O modules for the ATC-1000 controller has a defined set of pin assignments for how the outputs of the controller will be routed to individual pins on the various connectors of the I/O modules. For each of the modules, TS/2 Type 1, TS/2 Type 2, HMC-1000, and LMD, there is a default set of pin assignments. (For the TS/2 Type 1, this is actually a default set of pin assignments for the cabinet Bus Interface Units (BIUs), as fed to the cabinet through the controller’s Port 1, SDLC connector. i.e. The TS/2 Type 1 standard calls for digital output of the controller outputs through Port 1, to physical pins located on external devices (the BIUs).)

I/O Mapping is the feature that allows the controller to change these default pin assignments, so the user can decide to send the alarm outputs or preemption inputs, (or any of the controller inputs or outputs) to a completely different physical pin on the I/O module (or physical pin on the BIU, for TS/2 Type 1 controllers.)

To access the I/O Mapping features of the ATC-1000 navigate to:

Steady Red During Flash – When the controller is in flash mode, this value determines the number of seconds (a value between 0 and 255 seconds) that all channels flashing red are held at a steady red before the flash state can be exited. While the steady red is held, the yellow flashing channels will continue to flash yellow.

Request Time Sync – This feature is in support of the NTCIP AASHTO 1210 standard, also known as Signal System Master (SSM) support. SSM has not yet been fully implemented in the ATC-1000.

When a phase is red, the vehicle detector input calls for the phase to be serviced, but when the phase is already being serviced, a vehicle detector input instead serves to ‘extend’ the phase’s green period. Passage is the increment of time by which the phase green is extended. The passage timer counts down when no detector input is present, but it gets reset to its full value whenever a detector input is present. The phase is extended until either a gap occurs in vehicle flow, a force-off is applied, or if either of the maximum timers time out. Typical settings for Passage are from 0.5 to 5 seconds, depending on how sensitive or large the detector zones are. The possible range of values for Passage is 0.0 to 25.5 seconds.

Note Throughout this book, the time when the passage timer doesn’t get extended because a gap between vehicles of sufficient length has occurred is called the Gap-Out.

Maximum 1 – Maximum 1 timing is the default value used to set the maximum amount of time allowed for the green in this phase. For an actuated phase, this is the upper limit of the amount of green time allowed, as long as the phase is not in Maximum Recall mode. When Maximum Recall is not set to be ON for this phase, the Maximum 1 timer

Chapter 5 — Programming Menus

116 ATC-1000 Advanced Traffic Controller

times down only when a serviceable, conflicting call is present. The phase remains green until the Passage timer fails to be reset by a vehicle detection, or until the Maximum 1 timer reaches zero, whichever comes first. This timer will cease timing and reset if all serviceable calls go away. The timer will re-start, if a new call arrives and the active conflicting phases are in the Passage interval.

However, when Maximum Recall is set to be ON for this phase, the phase is always served and the Maximum 1 timer always counts down to, whether or not there is a call on the detectors of any other phase.

The value of Maximum 1 can vary widely, but to give a feel for the range, its value is typically between 8 and 17 seconds for left turns, between 12 and 25 seconds for side streets, and between 22 and 40 seconds for main streets.

Note If the Maximum 1 value is set to a very low number (such as zero) then minimum timing requirements for the phase, such as Min Green, will override it.

Maximum 2 – Maximum 2 is an alternate value for the maximum allowed amount of time allowed for this phase to be green. Max 2 is activated, on a ring by ring basis, by either an external input or by a TOD pattern change. When Max 2 is active the Maximum countdown timer will be loaded with the Maximum 2 value instead of the usual Maximum 1 time. When setting a value for the Maximum 2 field, the same concepts apply as with Maximum 1, except an alternate value is used. Maximum 2 is sometimes used during peak traffic periods (i.e. to generate longer main street flow times.) It is also sometimes used during coordination, so that phases won’t time out before being forced off.

Again, if the Maximum 2 time value is set to a very low number (such as zero) then minimum timing requirements for the phase, in other words, the Minimum Green value, will override it.

Clearance Timing Screens Collectively, the Green Timing Screens, the Clearance Timing Screens, and the Ped Timing Screens, function as the primary timing definition screens for the intersection. Each of these screens have two pages, the first for the first eight phases and the second for phases 9 through 16. The Clearance Timing Screens allow the user to set timing values for the yellow and red portions of each phase. (MAIN MENU > 2.PROGRAMMING > 2.CONTROLLER > 3.CLEARANCE TIMING)

Figure 100 – Clearance Timing Screen (Page 1)

Yellow Clearance – Quite simply, this is the amount of time the phase will spend showing the yellow signal. Yellow clearance can be set to any value between 3.0 and 25.5 seconds. Typical settings are from 3.5 to 5 seconds, based on the travel speed of traffic and the width of the intersection.

Red Clearance – Obviously, phases sit in red whenever other phases are being served, but there is a short period in the interval when switching from the service of one phase to the next when the intersection must sit in all red. Red Clearance defines how long this ‘rest’ period is. Values from 0.0 to 25.5 seconds can be entered, but typically this value is between 0 and 2.5 seconds. It is recommended that you use a time of at least 1 second for the Red Clearance value.

Red Revert – Red Revert time deals with special occasions when a phase may complete its service, and the timing circuit or the coordinator of the controller decides to service the exact same phase again. When this occurs, the red revert time serves as the minimum red time before the phase is switched to green again. It is usually set to a value that is higher than Red Clearance. Typically, Red Revert comes up when the controller is asked to switch into a preemption sequence, or when switching patterns during TOD operation. Values from 0.0 to 25.5 seconds can be entered.

Note The Red Revert time shown here varies from the Red Revert parameter visible on the Start-up Menu. The Red Revert is a unit global value, which is the value set on the Start-up menu. The parameter shown here, on the other hand, allows the user to set a red revert value per phase that is longer than the global value. The greater of the two values will be used.

Added Initial Timing Screens The next two screens concern a modification of basic actuated phase operation called “Volume Density” operation. Volume density is a way for an intersection to adapt to changes in traffic volume based on inputs from detectors. Volume density is composed of two parts: Initial time adjustments and gap reduction. Initial timing is set on this screen; gap reduction parameters are set on the next screen. (MAIN MENU > 2.PROGRAMMING > 2.CONTROLLER > 5.ADDED INITIAL TIMING)

This screen allows the operator to program the optional Added Initial parameter for each phase, as well as associated parameters. There are two pages for these parameters, the first one for phases 1 through 8 and the second page for phases 9 through 16.

Sec/Actuation – Also known as ”Added Initial” timing, this parameter is used to calculate an Added Initial timing period, based on detections during the non-Green intervals of a phase. The Sec/Actuation value for a phase is multiplied times the number of vehicles (detections) that are received while the phase is in the Yellow and Red states. This modified initial timing for a phase will be used only if the calculated Added Initial value is greater than the Min Green time and less than the Maximum time. (This is

normally Maximum1, but Maximum 2 will be used instead, if it has been invoked.) Typical settings: 2 - 3 seconds. About enough to move each vehicle.

Max Initial – Maximum Initial sets a limit on the amount of Added Initial. Added Initial can never exceed the maximum initial value. Also known as Max In, or Max Variable Initial. Typical settings: The Max Initial setting is normally set equal to the Initial interval that would be used if Volume Density were not used.

Important Since both Added Initial and Gap Reduction use vehicle detections for

red phases, both methods are based on the assumption that set-back detectors are installed. If the vehicle actuators are installed back (at least) several car length from the stop bar, this allows multiple vehicle detections to occur on phases where traffic is facing a red light.

ATC-1000 Advanced Traffic Controller 121

Gap Reduction Timing Screens Gap Reduction, along with the previous screen’s initial Timing parameters, are modifications of the basic actuated phase operation called “Volume Density” operation. Volume density is a way for an intersection to adapt to changes in traffic volume based on inputs from detectors. Gap reduction is a method to dynamically reduce the time allowed between cars needed to keep the green passage timer going, based on how long the green has continued and how many cars have been detected on other phases within the intersection. (MAIN MENU > 2.PROGRAMMING > 2.CONTROLLER > 6.GAP REDUCTION TIMING)

This screen allows an operator to set up Gap Reduction on the ATC-1000 controller. There are two pages of parameters, the first covers the parameters for phases 1 through 8 and the second for phases 9 through 16.

Figure 104 – Gap Reduction Timing Screen (Page 1)

Time B4 Gap Reduction – Also known as TBR, this NEMA parameter sets the Time Before Reduction value for Gap Reduction operations for this phase. The value can be between 0 and 255 seconds. This is the amount of time the controller will wait before it begins reducing the passage gap test to the Minimum Gap value. Time Before Reduction (TBR) starts timing when a conflicting call is received (i.e. when someone is waiting at another stop bar in the intersection,) which is often the beginning of green. If the TBR period counts down completely, or the Cars B4 Gap Reduction parameter is satisfied (whichever comes first), the controller will begin reducing the allowed gap in the Passage time for this phase. (Passage time is described on page 115.)

If all conflicting calls are removed before TBR has completed timing, the TBR timer will reset. Typical settings: 8 to 20 seconds. You need to allow enough time for queued vehicles to begin moving, since their initial speed will be slow, meaning their gap values will take too long, and gap reduction will begin too quickly. The value of Time B4 Gap Reduction (TBR) should be at least the value of Minimum Green plus 1 second.

Cars B4 Gap Reduction – This is an NTCIP object that is a slight addition to the normal NEMA Gap Reduction process. This parameter gives another way for gap reduction to

122 ATC-1000 Advanced Traffic Controller

begin. This value, which can be any setting between 0 and 255 detected vehicles, tells the controller to begin reducing the passage timer test whenever more than this number of vehicles are waiting at other stop bars in the intersection. Gap reduction will begin whenever either the TBR or the Cars B4 Gap Reduction thresholds are crossed.

Time to Reduce – Time to Reduce (TTR) is a NEMA parameter that establishes the time reduction step that the controller will use to begin a linear reduction of the phase gap (passage time) down to the minimum gap time. This value can be anything between 0 and 255 seconds, but typical settings are between 4 and 12 seconds. The size of TTR depends on how quickly the operator wishes to close the timing gap. A larger TTR closes the gap more quickly. If one wishes to close the gap immediately in one reduction step, the value of TTR should be the entire difference between the Passage time and the Minimum Gap value.

Minimum Gap – Minimum Gap is another standard NEMA parameter of the gap reduction process. The minimum gap value establishes the lowest acceptable gap (passage time) in traffic. The gap test will not be reduced below this amount. So if cars continue to cross the vehicle detectors at a rate that leaves no gaps larger than this Minimum Gap value, the Passage timer for the green portion of this phase will be extended right up until the Maximum timer times out. The acceptable range for minimum gap is from 0.0 to 25.5 seconds. Typical settings for Minimum Gap are from 1 to 3 seconds.

Note In the presence of a continuous vehicle actuation, the phase will not gap out even if Minimum Gap is set at zero.

Notes About the Usage of Gap Reduction

Gap reduction allows the normal passage time for a phase to be reduced linearly during the green portion of the phase. The parameters associated with this operation are called Time Before Reduction (TBR), Cars Before Reduction, Time To Reduce (TTR) and Min Gap. Thus, the longer demand holds a phase green even though a conflicting call is present, the closer the vehicles must be spaced to retain the existing green interval. The following are the two typical uses of gap reduction:

Controller Menu

ATC-1000 Advanced Traffic Controller 123

Classic Case Gap Reduction

In this case, set back loops, perhaps as far as several hundred feet back from the stop bar, are used to extend the phase. There may or may not be stop bar detectors, as well. (It is recommended that there are.)

Figure 105 – Classic Case of Gap Reduction

The Passage timer value is set based on the travel time for a vehicle to get from the set-back detector to the intersection. This value could be fairly long; if left alone, this would tend to cause the intersection to run sluggishly, since the phase would constantly extend, even with widely gapped traffic. By using gap reduction, the passage value can be reduced down enough to provide good gap control.

Gap Reduction as an Efficiency Tool

Even with normal stop bar detectors, Gap Reduction can be an effective way to increase efficiency without getting “the green is too short” complaints. The idea is to begin the phase with a fairly long passage time when vehicles are moving slowly, then move to a shorter time later, when they are moving at the flow rate. Gap reduction is thus a good way to obtain “snappy” operation, so that phases cycle crisply without long waits, but also without complaints. which are often the case when Passage times are simply set to low values.

Dynamic Maximum operation can be activated for a particular phase by setting non-zero values to the following parameters. Dynamic Maximum operation functions in NEMA phase-based patterns only. It functions on top of the normal Max1 and Max 2 parameters for a given phase. It functions like this: if a phase ‘Maxes Out’ twice in a row, the maximum value of the phase begins stepping upward. Each time after that the phase maxes out again, the maximum steps upward again, until an ultimate maximum is reached. If this upward stepping is active and the phase gaps out rather than maxing out, the dynamic maximum steps downward instead.

Controller Menu

ATC-1000 Advanced Traffic Controller 125

Dynamic Max Limit – This is the upper limit on the duration of the green, in seconds, that the phase can be granted as a result of Dynamic Max adjustments. Note that if this value is lower than the Max1 and Max 2 limits, then the downward stepping mode of Dynamic Max operation can actually shorten the maximum green time for this phase all the way down to this lower value. This can be any value between 0 and 255 seconds.

Dynamic Max Step – This is the number of seconds that are added to the phase’s maximum green value after the phase has maxed out twice in a row. This stepping upward continues until the Dynamic Max Limit is reached or the phase fails to max out once. Dynamic Max stepping will also be deactivated if one of these conditions exist for this phase:

A failed detector on the phase

Maximum recall is triggered

Dynamic Max Step can be set to any value between 0.0 and 25.5 seconds, in tenths of a second. The size of this step depends on how quickly you would like the intersection to respond to a sudden flux of traffic. Larger step values can be used to make the intersection respond more quickly.

Call to Non-Act 1 — Call to Non-Actuated, or “CNA” operation, is a method of phase timing (in NEMA phase-based patterns only) in which vehicles and pedestrian detectors are not required in order to serve the phase. CNA is often used when it is desired to hold the coordinated phase in Walk during coordination. Min-Recall and Ped Recall are automatically activated, and phase detectors are disabled for phases set to CNA. The most significant aspect of the CNA mode is that during the hold period while in coordination, the CNA phase will hold at the end of walk instead of the end of green. Ped Clear then follows just before phase termination. The advantage of using CNA for coordinated phases is that the length of walk is determined by the coordinated phase

split time. In this way, the walk duration varies depending on the cycle and split selection, i.e. Walk time = split time – (PedClearance + Yellow + Red). Place a check (‘X’) in this row to set this phase to be a CNA1 phase.

A CNA phase contains four Green states, defined by NEMA as States A, B, C and D. State A is Walk Timing, State B is Walk Rest or Walk Hold, State C is Ped Clearance, and State D is Green Dwell/Select.

State A: Walk Timing – Upon initial entry into phase, Walk times provided Ped Omit is not on.

State B: Walk Hold – Upon completion of Walk Timing, the phase “holds” in walk if Hold is applied.

State B: Walk Rest– The phase “rests” in Walk if Hold is not applied, the Walk Rest Modifier (WRM) is applied, and no serviceable conflicting calls exist. The phase leaves the Walk Rest/Hold state and advances to Ped Clearance when:

a.) The phase is in Walk Rest and a serviceable conflicting call is registered, or

b.) The phase is in Walk Hold, a serviceable conflicting call exists and Force Off is applied, or

c.) Hold is released and the WRM is not active, regardless of the presence of a serviceable conflicting call.

State C: Ped Clearance – The phase times the Ped Clearance setting, and then advances to the Green Dwell/Select state.

State D: Green Dwell/Select – This is the state in which the controller does one of the following things, based on the current conditions:

a.) Immediately selects the next phase to be serviced and proceeds to yellow clearance, or

b.) it rests in Green/Don’t Walk if a call exists and concurrent timing constraints exist, or if WRM and Ped Recycle are not active, or

c.) it returns to Walk if no serviceable conflicting call exists and either WRM or Ped Recycle are active, and Ped Omit is not active. Once a CNA phase has left the Walk state, Hold and Force Off do not have an effect on the termination of the phase. That is, Force Off does not have to be maintained throughout Ped Clearance in order to terminate the green, nor will Hold maintain the phase in Green/Don’t Walk.

Call to Non-Act 2 — Place a check (‘X’) in this row to set this phase to be a CNA2 phase. CNA2 operates the same as CNA1, but it provides an alternative phase selection method for Call to Non-Actuated operation, usually for cross-arterial coordination.

Chapter 5 — Programming Menus

128 ATC-1000 Advanced Traffic Controller

Dual Entry — Place a check (‘X’) in this row to set this phase to be a Dual Entry phase. Dual Entry works in conjunction with the compatibility matrix of phases. (See page 95) Dual Entry is a flag on a phase that tells the controller that if a phase in the other ring comes on by itself, the controller can look across the barrier for a compatible phase that is marked as Dual Entry, and it will select one to turn on. This ensures that there will always be a phase on in each ring whenever the compatibility matrix permits it. Dual Entry is typically used during multi ring operation, to prevent a single phase from being served at a time. For example, suppose phase 8 gets called. The controller might serve it alone, except it notices that across the ring barrier, phase 4 is listed as both compatible with 8, AND it is a Dual Entry phase, so the controller goes ahead and turns phase 4 on at the same time.

Simultaneous Gap Out — Place a check (‘X’) in this row to set this phase to be a Simultaneous Gap Out phase. Simultaneous Gap Out, sometimes known as ‘SGO’, allows a phase’s passage timer to re-start if it has timed out and the phase is waiting to cross a barrier. With SGO enabled and calls on Phases 2 and 6, the Phase 4 passage timer can start again if a new vehicle arrives. If Phase 4 then extends and Phase 8 gaps out, Phase 8 can start its passage timer again. This operation can continue back and forth until both phases Max Out or they both “Simultaneously Gap Out”, hence the name. When Simultaneous Gap Out is disabled, the phase passage timer cannot restart once it times out for the selected phases and is waiting to cross the barrier. If phase 4 goes to rest while 8 is extending, then 4 cannot start its passage timer again. Both phases will then gap out as soon as phase 8 does. So phases will tend to gap out sooner with SGO disabled than when it is enabled.

Guaranteed Passage — Place a check (‘X’) in this row to set this phase to be a Guaranteed Passage phase. When this is enabled for a phase that is operating in volume density mode, meaning it is using gap reduction, it allows the phase to retain the right-of-way for the unexpired portion of its Passage timer, following the decision to terminate the Green due to a reduced gap.

Actuated Rest in Walk — Place a check (‘X’) in this row to set this phase to be an Actuated Rest-in-Walk phase. This was called ‘Walk Rest’ or ‘WR’ in the 3000E controller. Allows the selected phase to rest in Green-Walk instead of Green-Don’t Walk, as long as there is no serviceable conflicting call at the end of the Walk timing.

Conditional Service — Place a check (‘X’) in this row to set this phase to be a Conditional Service phase. This is typically used to allow a left turn phase to be served twice in the same cycle; once as a leading phase and once as a lagging phase. This is only possible in a non-coordinated intersection. The following conditions are required to allow a conditional service phase to function in this way:

there is a call for service on a leading left-turn phase

the intersection is not working in coordination with any other intersection

Controller Menu

ATC-1000 Advanced Traffic Controller 129

There is a conflicting call on the opposite side of the barrier. Otherwise, the left-turn phase would be serviced automatically by standard actuated controller behavior, and conditional service isn’t required.

The through phase of the phase pair that includes this left turn has Gapped out.

The time remaining on the through phase’s maximum timer is larger than the left-turn’s minimum conditional service time.

Note that although conditional service is usually used to allow a second left turn during a cycle, it can in fact be used for any phase that meets the above criteria; just replace the ‘left-turn phase’ term in the requirement with ‘the conditional phase’.

Added Initial Calc — Place a check (‘X’) in this row to set this phase to be an ‘Added Initial’ phase. Added Initial is a form of Variable Initial timing, which increases the initial green interval of a phase based on the demand for that phase that is measured during the preceding yellow and red periods. The extra time allows a platoon of vehicles to proceed through the intersection before the passage time becomes active. The added-initial option is generally used when long minimum green times are specified. This method counts the number of detector counts during the non-green portion of the phase and uses that to add a multiple of the added initial time to the minimum green time. The total initial time will not exceed the defined Max initial time. The controller will compare all of the detectors associated with this phase and use the one that collected the largest number of vehicle counts. The values used in these calculations are entered on the “Added Initial Timing Screens”; see page 119.

Recall Screens The Recall screen is used to define phase-by-phase recall options for the controller. A recall is a way to create recurring calls for service by phases, even when no real call exists. This is a way to ensure that phases are serviced in the case that detectors are faulty, vehicles miss the detector hot zone, or the pedestrian fails to push the button properly. Recalls can be set for the vehicle and the pedestrian portions of a phase separately. There are two pages of recall screens; the first allows the operator to set the five recall options for phases 1 through 8, the second page allows them to set the same options for phases 9 through 16.

Vehicle Minimum – Place a check (‘X’) in this row to set this phase to have a Vehicle Minimum Recall, also sometimes known as just a ‘Min Recall’. A minimum recall assures that the phase will always be serviced and will time the Initial green, but any further

green is dependent on detector extensions. (If detections are present, the phase can time up to the Max time.) If there is no demand on the phase, the controller will time the Initial interval only, then it will either rest (if there is no other demand) or advance to the next phase that has demand. A phase can operate in either Min Recall or Max Recall, but not both. If both are selected, then Max Recall will be used.

Vehicle Maximum – Place a check (‘X’) in this row to set this phase to have a Vehicle Maximum Recall, also sometimes known as just a ‘Max Recall’. This is similar to Min Recall, except that the phase will time the entire max time regardless of demand. Upon termination of the Max timer, the phase will either rest or advance to a phase that has demand. Maximum 1 is the default maximum used. Maximum 2 can be selected via an external input or via a Time of Day Action. Max Recall is typically used for any phase that is to be “pre-timed” i.e. it has no detection but must be served. Often used on a main street with no peds (or actuated peds) in a semi-actuated application where the side is actuated but the main street is not. Note that Max Recall should not be applied to phases with functional detection. It is sometimes applied to an actuated phase temporarily when detection fails. A phase can operate in either Min Recall or Max Recall, but not both. If both are selected, then Max Recall will be used.

Pedestrian Recall – Place a check (‘X’) in this row to set this phase to have a Pedestrian Recall, also sometimes known as just a ‘Ped Recall’. The pedestrian movement on this phase will be serviced once per cycle.

Detector Non Lock – Non-Lock disables vehicle call memory on selected phases. The phase only recognizes vehicle presence so that the detector must be continuously occupied in order to maintain a call for service. Note that the default mode is non-lock disabled (no “X”), which means that memory is on. Program an “X“ for phases to operate in Non-Lock mode (i.e. memory off, presence mode).

When Non-Lock is not enabled (locking mode), if the phase terminates with time remaining in the Passage Timer (i.e. Max, Force Off, Interval Advance), a call will be left on the phase and the unit will cycle back to it until the call is serviced.

Non lock enabled (X) should be used for phases where the detection zone is sufficient for presence type detection and vehicles must occupy the detector zone to be served. If these vehicles leave before phase service, the call is forgotten, (i.e. Right Turn on Red or Permissive Left Turn completed). Non-Lock disabled (no “X”) should be used when the detector call must be retained until phase service, such as when the detection zone is set back from the stop bar, or when it is easy for a vehicle to overrun the stop bar detector.

Soft Recall – Place a check (‘X’) in this row to set this phase to have a Soft Recall. Soft Recall will only place a call on the selected phases if no real calls exist and the controller is not already resting in one of these phases. It allows the unit to cycle between all phases, and when demand ceases, rest in the programmed phase(s).

Chapter 5 — Programming Menus

132 ATC-1000 Advanced Traffic Controller

Note If Soft, Min and Max recalls are all set for the same phase, Max Recall will take precedence.

It should be noted that there is a distinct difference between Soft and Min Recall, even when used in a 2-Phase operation. The difference is apparent if, for example, Phases 1 and 2 both have Max Times of 20 seconds, there is no real call on Phase 2, and Soft Recall is applied to Phase 2. In this case, Phase 1 can extend in Passage indefinitely. (Phase 1’s Max timer does not count down.) If Min Recall were applied to Phase 2 in this situation, Phase 1 would max out after 20 seconds and then serve “demand lacking” Phase 2, despite there still being demand on Phase 1.

Soft Recall is typically used on a fully actuated intersection. Soft Recall allows the unit to always go back to and rest in main street Green when there is no demand (or recalls)—but without interfering with other phase service.

For example, at a 3 phase intersection, say that phase 2 is the main street with Soft Recall mode set. If there is demand on Phases 1 and 3 only, the controller will cycle between Phases 1 and 3 only, without servicing Phase 2*. It is only when there is no demand at all that Soft Recall will be applied to Phase 2. If Min Recall had been applied to Phase 2, the unit will always cycle through Phase 2 when going from Phase 1 to 3.

Note In order for Soft Recall to work properly, the Soft Recall programmed phase(s) must have detection.

* Phase 2 will be served normally if there is real demand. (i.e. Cars are actually on the detector.)

Figure 114 – Overlap Screen (Page 4)

An Overlap is a set of G-Y-R outputs that are associated with one or more phases. The overlap forms a separate movement that derives its operation from its assigned phases, commonly called “parent phases.” A typical overlap will be active during two or more parent phases such that if any parent is green, the overlap is green as well.

If the controller makes a “phase next” decision to clear from one parent phase to another, the overlap will remain green throughout. If the controller decides to clear from a parent to a non-parent, the overlap will clear with the parent using the parent’s yellow and red duration. Furthermore, in multiple ring configurations, more than one parent phase may be active at a given time. If a “phase next” decision is made to clear from a parent to a non-parent, and a parent phase is green in another ring, the Overlap remains green.

Parents – Phases during which the overlap is allowed to be green (see Overlap general description previous). For standard overlaps, only the parent phases need to be programmed. Per the NTCIP 1202 standard, section 2.10.2.3, the overlap will be green whenever a parent phase’s output is green, and whenever the controller is changing between parent phases.

Trailing values – These numbers represent the time, in seconds, that the overlap termination is delayed (i.e. a double-clearing overlap) relative to the parent phase.

Type – The type of overlap determines the logic that will be used by the overlap. Overlap Types are defined by the NTCIP 1202 standard, section 2.10.2.2 (i.e. the “overlapType object” section.) The available type options are shown in Table 13. This is a read-only value. The ATC self-selects the ‘type’ based on the user programming of the overlap parameters.

Controller Menu

ATC-1000 Advanced Traffic Controller 135

Table 13 – Available Types of Overlap

Type Overlap Type 1 Other, not NTCIP (Advanced Overlap)

2 Normal (Standard) 3 Minus Green - Yellow

By the NTCIP 1202 standard, a Type 2 (Normal) overlap is controlled by the Parent phases. The overlap output is green in the following situations: (1) when a Parent phase is green, or (2) when a Parent phase is yellow (or in red clearance) and another Parent phase is next. The overlap output is yellow when a Parent phase is yellow and no Parent phase is next. Otherwise, the overlap output is always red.

By the same standard, a Type 3 (Minus Green-Yellow) overlap is controlled by the Parent phases and the Modifier phases. For a Type 3 overlap, the overlap output is green in the following situations: (1) when a Parent phase is green and all Modifier phases are also green, or (2) when a Parent phase is yellow (or in red clearance), another Parent phase is next, and all Modifier phases are also green. The overlap output is yellow whenever a Parent phase is yellow and a Modifier phase is NOT yellow and no Parent phase is next. Otherwise, the overlap output is always red.

Overlap Channels and Compatibility

Overlap operation is sometimes a source of confusion for users, especially when it comes to overlap compatibility. To help clear this confusion, the figure below shows a typical mapping of phases and overlaps to monitor (MMU) channels for an example phasing. Load switches 1 through 5 are shown in Figure 115, with their typical assignments.

Figure 115 – Typical Load Switch assignments

Note that the overlap is on a separate load switch which is driven by OVERLAP A, which in turn has been assigned phases 1+2 as parents. CH1-CH5 indicates the Conflict Monitor (or MMU) channel assignments.

Chapter 5 — Programming Menus

136 ATC-1000 Advanced Traffic Controller

Note also that the appropriate channel compatibilities are:

1-5

2-5

The channel compatibilities are definitely not 1+2 as is sometimes thought. It is important to be able to make the distinction between the overlap and its compatibilities vs. its parents and their compatibilities. The overlap is a separate movement and its parents are not necessarily compatible with each other (and are usually not.)

Pedestrian Overlaps This screen allows for the configuration of up to eight pedestrian overlap phases. Ped overlaps are ped phases that are separate from the normal 16 available pedestrian phases. They are conditional, meaning that their states are linked to one or more of the main 16 vehicular phases. To differentiate them from ordinary phases, ped overlap phases are typically labeled with letters rather than numbers (i.e. Overlap A through H.)

COORDINATION MENU

Coordination is the process of keeping multiple intersections working together in a group timing pattern. This allows for ‘green wave’ movements along main streets, and similar types of coordinated intersection actions. The screens under the Coordination menu allow you to configure the ATC-1000 controller to function in a coordinated environment.

This section of the manual describes the screen-by-screen, and parameter-by-parameter values used to program coordination. For a discussion of the actual process of programming the ATC-1000 to achieve coordinated operation, refer to “Chapter 6 — Coordinated Operation”, starting on page 181.

Figure 119 – Coordination Variables Screen

Operational Mode – This number (a value between 000 and 255)sets the overall operational mode for coordination on the ATC-1000.

Table 14 – Operational Mode values

Operational Mode Definition 0 Automatic mode – This mode provides for coordinated operation, Free

and Flash to be determined automatically by all possible sources: Interconnect, Time Based events, or System Commands. This is the normal default mode for most systems.

001 - 253 Manual Pattern mode – Coordinated operation running the specified number pattern (Pattern 001 to Pattern 253). This selection of pattern overrides all other pattern commands, including System Commands.

254 Manual Free mode – This mode provides for Free operation without coordination, or Automatic Flash from any source.

255 Manual Flash mode – This mode causes the controller to run in the Automatic Flash state, without coordination or Free operation.

Correction Mode – Defines which coordination correction method will be used when establishing a new or different offset from the coordinated time. Setting this value to anything other than ‘other(1)’ will automatically set the USTC Correction Mode parameter to be ‘other(1)’. DO NOT SET both Correction Mode and USTC Correction Mode to be ‘other(1)’ at the same time!

Coordination Menu

ATC-1000 Advanced Traffic Controller 141

Table 15 – Coordination Correction modes

Correction Mode Description other (1) The coordinator establishes a new offset by a mechanism not

defined in the NTCIP standard. This tells the coordinator to use the USTC Correction Mode.

dwell (2) When changing the offset time, the coordinator will dwell in the coordinated phases until the desired offset is reached.

shortway/Smooth (3) When changing the offset time, the coordinator adds or subtracts time to/from phase timings with the aim to limit the amount of time the cycle length changes.

addonly (4) When changing the offset time, the coordinator adds time to phase timings with the aim to limit the amount of time the cycle length changes.

USTC Correction Mode – These are the proprietary USTC (U.S. Traffic Corporation) coordination correction methods. To access these options, the main Correction Mode value (above) must be set to option 1: other. Setting this value to anything other than ‘other(1)’ will automatically set the Correction Mode parameter to be ‘other(1)’. DO NOT SET both Correction Mode and USTC Correction Mode to be ‘other(1)’ at the same time. The possible values for USTC Correction are:

Table 16 – USTC Coordination Correction modes

USTC Correction Mode Description Toronto (0) The coordinator establishes a new offset by using the City of

Toronto offset correction strategy. Refer to “Toronto Offset Correction Ext/Reduce” on page 144.

Other (1) This value should be used whenever the ‘Correction Mode’ parameter is set to anything other than ‘other(1)’. This value means, use the Correction Mode method.

Maximum Mode – This parameter determines which maximum time, if any, is used during coordinated operation. The possible values are:

Table 17 – Coordination Maximum modes

Maximum mode value Description other (1) The maximum time to use during coordination is not defined in

the NTCIP standard. In practical terms for the ATC-1000, this means that there is no maximum time used during coordination.

maximum1 (2) While coordination is running a pattern, the coordinator will use Max 1 as the maximum phase time.

maximum2 (3) While coordination is running a pattern, the coordinator will use Max 2 as the maximum phase time.

maxInhibit (4) Internal maximum timing is inhibited while coordination is running a pattern.

Chapter 5 — Programming Menus

142 ATC-1000 Advanced Traffic Controller

Force Mode – This parameter determines which ‘pattern force mode’ the ATC-1000 coordinator will use. The possible values are:

Table 18 – Coordination Force Mode options

Mode Description other (1) No force off mode is used.

floating (2) Each phase will be forced to the new split time after the phase becomes active. This allows unused split time to be passed to the coordinated phase.

fixed (3) Each phase will be forced to the new split time at a fixed position in the cycle. This allows unused split time to pass to the following phase.

System Pattern – This parameter defines how the controller will react when it receives a called System Pattern. This is the value that is set by the central system to control the device’s pattern from central. The possible values are:

Table 19 – System Pattern modes

System Pattern mode Description 0 Standby mode – The system relinquishes control of the device. The

controller runs the pattern specified by TOD. 1 - 253 Pattern # – The system commanded pattern (Pattern 1 to Pattern 253.)

254 Free mode – The controller runs in Free mode. 255 Flash mode – A call for the device to enter Automatic Flash.

If an unsupported or invalid pattern is called by the central system, the ATC-1000 will run in Free mode. The value of System Pattern is ignored if the controller is in Backup mode. Any changes sent to this value will reset the Backup timer to zero (0).

Pattern Table Screens Coordinated intersections don’t work with a single cycle time. Rather, they work with a cycle, offset, and split goal that is then coordinated with the other intersections on a roadway artery. This screen provide three pages of places to define different Cycle-Offset-Split patterns. Each cycle-offset-split combination is known as a ‘pattern’. The ATC-1000 Controller can be programmed with up to 48 different patterns. (MAIN MENU > 2.PROGRAMMING > 3.COORDINATION > 2.PATTERN TABLE)

Split Table Screens The split table is used to define what ‘split’ of the overall cycle time each phase will take up. The ATC-1000 controller will accept up to 16 different defined splits for the intersection. A split table number is referenced in each column of the Pattern table screens, so each defined pattern calls one of these defined split tables, which is a large part of what defines each pattern.

Toronto Offset Correction Percent Again, on this screen, the values set here are only used if Correction Mode = other(1) and USTC Correction Mode=toronto(0) on the Coord Variables screen. This screen is used to set a percentage value for each of the 48 available NEMA patterns in the controller. The percentage is used to determine whether phase extension or phase reduction should be used when the controller needs to offset in an attempt to get back to coordination.

Figure 123 – Offset Correction Extend/Reduce Splits as Percentages

The available values are between 0 and 99 percent, which indicates how far out of sync the start of this controller’s cycle is from the coordination point. This is the percent of the full cycle duration and it indicates the threshold between reduction actions and extension. So if the percentage set on this screen for pattern 1 is 20%, and the controller is currently running pattern 1, and its currently lagging the coordination point by 15% of its cycle length, the controller will start reducing phase split times (using the values set on the “Toronto Offset Correction Ext/Reduce” screen, see page 144). On the other hand in this scenario, if the controller is lagging the coordination point by 25%, then the controller will start extending phases (again, by the Extend values defined on the “Toronto Offset Correction Ext/Reduce” screen) in order to get back into coordination.

Event # – Each Day Plan can have up to 16 events, each defined by the time of day that the event occurs, and the Action to call at that time. This is non-editable piece of text that labels each event ‘box’ in the day plan. If the action associated with the event is ‘0’ (zero), then that particular event is ignored.

Hour – This is a two digit number that indicates the hour in which the action should occur. This is a military representation of the time, so the hour after midnight would be represented by ‘0’, and 2:00 in the afternoon would be represented by ‘14’.

Min – This is the minute in the hour when the action will be called. Valid values for Min are any number between 0 and 59.

Action – This is the number of the Action that will be called at this event’s time. If the value is ‘0’ (zero), then the event is ignored by the controller.

Schedule Screens A Schedule is also known as a Year Plan. It defines what months, weekdays, and days of the month of a generic year will call each of the controller’s Day Plans. There are 32 schedules that can be configured. All schedules are followed by the controller, but if the same day is assigned to multiple day plans, the highest numbered Schedule will take precedence.

As the screen states, the Current Timezone and DST Status values cannot be edited on this screen. The values shown there reflect the settings that have been entered elsewhere in these Time of Day screens. To edit times in Global time rather than local time and to edit your time zone setting (Local Time Differential), you’ll need to use the Advanced Time Setup Screen. Daylight Saving Times values are edited on the Daylight Saving Setup Menu.

Advanced Time Setup Screen This screen provides another, more advanced way to edit your controller’s time and date values. On this screen, date and time are set in Greenwich Mean Time (also known as GMT, Universal Time, or for military types, Zulu.) You also need to specify how far off the local Standard time is from GMT. This Local Time Differential is entered in seconds. So to set the local clock to a time zone that is GMT minus 5 hours, which is Eastern Standard Time, you would enter a Local Time Differential of -18000 seconds. (5 hours × 60 minutes per hour × 60 seconds per minute) Refer to the “Setting the Date and Time” topic on page 22 for details on setting the time differential.

Figure 135 – Advanced Time Setup screen

Use the + E keypad combination to enter and exit Edit mode. An ‘*’ will show up in the upper right corner when you are in Edit mode. Use the up and down arrow buttons to switch between the fields. The Global Time and Date values are the numerical values of the current date and time at Greenwich, England. The Differential is the offset, in seconds, from Greenwich time. There are 3600 seconds for each hour your time zone is offset from GMT. You will need to edit the plus and minus symbol first, and then press the right arrow button to switch to the numeric part of the time differential value. Time zones to the West of the Meridian are a negative differential (i.e. the time is earlier), and zones to the East of the Meridian have a positive differential (the time is later.)

Pattern Sync — For coordinated operation, all of the controllers need to have a common ‘zero’ point to use to calculate their offset timers. Typically, the default is midnight of every day as the time when the cycle offset is set back to zero. Of course, if all of your controllers suddenly generate a large offset at midnight due to this syncing action, they will all suddenly start large offset seeking timing actions, which could cause sudden changes in split times right after midnight. Many municipalities have opted to set the time to occur later, when traffic is lighter for these actions. This value is the number of minutes after midnight when this pattern sync should occur. Example: So if you would like the pattern sync to occur at 2:00 am, all of the controllers in your system should be set to have the same Pattern Sync value: 120.

Daylight Saving Settings Menu This menu provides a host of options to view, modify, or disable the daylight saving parameters for the ATC controller. Daylight saving time, or ‘Summer Time’ in some countries, is the adjustment of local time to allow for a longer daylight period in the afternoon and a shorter amount of daylight in the morning. This is typically started in early Spring as the days begin to get longer, and ended in late Fall as the days shorten. (This is, of course, true in both the Northern and Southern hemispheres, although Spring starts in March in the North and in September in the South, so the dates will be different.)

Options 1, 2, 4, and 5 are used to modify the current DST settings. In particular, Option 1 loads a default DST set of parameters which correspond to the normal Daylight Saving time values in the United States, namely:

The Default DST begins on the second Sunday in March, at 2:00 AM local time. Local time is set forward one hour, so it becomes 3:00 AM local time.

The Default DST ends on the first Sunday in November, at 1:00 AM local time. Local time is set backward one hour, so it becomes 12:00 midnight.

Figure 144 – Vehicle Detector Options Screen (Page 1)

Note For all of these per-detector functions, it’s important to remember that the detectors are not associated with individual phases on this screen. Rather, detector-to-phase association is defined on the “Detector Call Phases Screen”, which is described on page 166.

Chapter 5 — Programming Menus

164 ATC-1000 Advanced Traffic Controller

Call – Place a check (‘X’) in this row under a detector indicates that a detection will place a call for service on the phase associated with this detector, whenever that phase is not timing a Green interval.

Queue – Place a check (‘X’) on this row under a detector to indicate that this detector is used for gap detection. A queue detector will extend the Green interval of the assigned phase until a gap occurs, or until the Green phase times longer than the optional queue limit.

Add Init – An ‘X’ placed in this row beneath a detector indicates that that detector will be used to generate detection inputs for the Added Init function of Initial Green extension. The method used is to count the vehicle detections from all detectors associated with the phase, take the detector with the highest count total, and multiply that count total by the Added Init time step. This extra time is then compared to the minimum and maximum time in effect and utilized, but only if it is greater than the minimum and less than the maximum.

Passage – When this row is checked (‘X’) the controller will maintain a reset of the associated phase’s Passage Timer for the duration of the detector actuation, while the phase is green.

Red Lock – When this row is checked (‘X’) the controller will lock a call to the assigned phase if an actuation occurs while the phase is not showing green or yellow.

Yel Lock – When this row is checked (‘X’) the controller will lock a call to the assigned phase if an actuation occurs while the phase is not showing green.

Occ Det – When this row is checked (‘X’) then this detector is marked as an ‘occupancy detector’. An occupancy detector collects data for the associated phase’s occupancy calculations.

Vol Det – When this row is checked (‘X’) then this detector is marked as a ‘volume detector’. A volume detector collects data for the associated phase’s volume calculations.

Reset – This sends a reset command to the detector, forcing it to return to FALSE (0) after the reset command. A reset command is an interactive control that is not stored in the controller database. The reset command is sent as soon as you press Yes on the keypad.

Note A reset command may reset more than one detector, if other detectors are attached to a common reset channel, as is often the case.

Figure 145 – Vehicle Detector Timing Screen (Page 1)

Delay – A number between 0.0 and 255.0 that indicates the number of seconds that are added as a delay on the input whenever the detector’s output goes ON. (True). This delay is added whenever the detector’s assigned phase is not green.

Extend – A number between 0.0 and 25.5 that indicates the number of seconds that a detection ON signal is read beyond the point where the actual detector’s output goes OFF.

Queue – A number between 0 and 255 that indicates the number of seconds that the actuation from a queue detector will continue into the associated phase’s green. This time begins when the phase becomes green and when this count expires, associated detection inputs will be ignored. (This time may be shortened by other overriding parameters assigned to this phase, including Max times, Force-Offs, etc.)

No Act – A number between 0 and 255 that indicates the number of minutes used by the detector’s No Activity diagnostic. If an active detector does not exhibit an actuation for the specified period of time, it is considered a fault and the detector is classified as ‘failed’. A value of ‘0’ disables the No Activity diagnostic for this detector. A failed detector can disable the Add-Init, passage, and extension timers on the associated phase, among other side effects, so use this feature with care.

Max PRS – This is the length of time in minutes, from 0 to 255 minutes used by the detector’s Maximum Presence diagnostic. If an active detector exhibits continuous detection for too long a period, it is considered a fault and the detector is classified as ‘failed’. A value of ‘0’ disables the Maximum Presence diagnostic for this detector. A failed detector can disable the Add-Init, passage, and extension timers on the associated phase, among other side effects, so use this feature with care.

ERR CTS – Used by the Detector Erratic Counts diagnostic, this is the number of counts per minute, over which, the detector will be considered faulty. This can be any value

166 ATC-1000 Advanced Traffic Controller

between 0 and 255 counts per minute. If an active detector exhibits excessive actuations, it could be a sign of an intermittent connection in the wiring or some other “chattering” problem. A failed detector can disable the Add-Init, passage, and extension timers on the associated phase, among other side effects, so use this feature with care. A value of ‘0’ (zero) disables the Erratic Counts diagnostic for this detector.

Fail T – The amount of time, from 0 to 255 seconds, used as the Detector Fail Time. If a detector diagnostic (one of the above three functions) has tagged a detector input as ‘failed’, this function tells the controller to place an artificial call on the associated phase for this many seconds during all non-green intervals. The call remains ON for this many seconds into the green section of the phase.

USING THE PRETIMED MENU

Most of the interface and controls for the ATC-1000 have an implicit assumption that most users of the controller will be working with a NEMA style, actuated, phase-based operation in their traffic cabinets. This includes the preemption, TSP and most other parts of the interface. The Pre-timed menu is where most of the settings are located to operate the other type of traffic pattern control in the ATC-1000: pre-timed interval based, rather than NEMA phase-based. Whereas phases assume signals respond to provide traffic ‘movements’, pre-timed operation is more concerned with signal outputs.

SYSTEM MAINTENANCE MENU

The System Maintenance menu on the ATC controllers is used to load and copy controller databases and to access the diagnostics system. It is also the menu to use to update the firmware of the controller. Be aware that entering the diagnostics mode on the Utilities menu will take the intersection into Flash operation. The controller will need to be powered down and restarted to exit the System Maintenance Diagnostics screens.

(MAIN MENU > 3.SYSTEM MAINTENANCE)

Note The Diagnostics available here is different from those available when pressing + Voltage (MNU) on the keypad. Those diagnostics are a lower level hardware based set of diagnostics, particularly aimed at the interface circuit board and the operation of the keyboard and display. (Refer to “Utilities Menu” on page 290.)

Database Utilities Screen The ATC-1000 maintains a couple of pre-configured intersection databases in memory that can be loaded into your primary database. This is a quick way to get a new controller set up with a basic set of parameters that you can then modify. It also provides a way to zero out the controller’s internal memory.

(MAIN MENU > 7.SYSTEM MAINTENANCE > 1.DATABASE UTILITIES)

3.1 DATABASE UTILITIES 0. Remove ALL Flash Data. 1. Load simple 8ph 2r. 2. Load 8ph 2r with Coord/Preempt

Figure 153 – Default Database Load screen

Caution Loading either of these default databases will over-write all

of your current settings.

Remove ALL Flash Data – This will remove all of the configuration values stored in the controller. This will not affect the firmware itself, but it will remove all programming that you have done to the controller. This function sets all values in the ATC-1000 internal database to zero (0).

Load Databases – From the Default Database Load screen, you can opt to load a simple 8 phase, dual ring configuration into active memory on the controller, or an 8 phase, dual ring configuration that is also set up to use coordination and preemption. When you choose one of the above options, a data file will be decompressed and installed into your active memory on the controller.

DECOMPRESSING DATA FILE

When the decompression is complete, the controller will report that this function is ‘Done’.

Copy Database Functions The Copy Database Data screens provide a method to copy the contents of one area of database memory into other similar areas. There are many places in the controller database where multiple instances of the same type of data exist:

16 NEMA phases

48 TSP Action Plans

64 Detectors

4 Overlaps

These are just a few examples. In any location where multiple instances of a particular data type exist, the Copy Database Data menus provide a screen to copy data from one instance to another, to several others, or to all of the others. This is a quick way to set up one phase, detector, or overlap in the manner you wish, and then copy that data over to the others as a template that can be modified for each.

There are separate sets of copy screens for the Actuated and Pretimed portions of the database. First, choose which type of data you wish to copy.

(MAIN MENU > 3.SYSTEM MAINTENANCE > 2.COPY DATABASE DATA)

3.2 COPY DATA 1. Actuated 2. Pretimed

Figure 157 – Copy Database Functions screen

Next, when you get into the Actuated or Pretimed Copy Data menu (We’ll show the Actuated Copy menu here, just as an example) you need to pick which type of data you would like to copy.

7.2.1.1 PHASE DATA COPY FROM: 001 COPY TO : 0000 A = ALL C# = all data up to # element 16 = allowed max

Figure 159 – Copying Phase Data screen

Once you’ve chosen the type of data you would like to copy, you will be presented with the same type of screen no matter what the exact data is. On it, you only need to specify a source (COPY FROM) and destination (COPY TO) for the copy function.

COPY FROM – The Copy From field is the simpler one to fill in. It must be a single instance of the data type. Usually one edits the first instance, and copies Phase 1 into all of the other phases you wish to use, say phases 2 through 8. In this case, we just enter the number ‘1’ in this field.

COPY TO – The Copy To field has a few options, as shown in the hints just below the Copy To field.

System Maintenance Menu

ATC-1000 Advanced Traffic Controller 177

You can specify a single instance of the data, say ‘2’, so you would copy phase ‘1’ data into the phase 2 instance. The bottom row of hints shows you what the highest acceptable number instance is for this type of data.

You can specify the letter ‘A’, using the A key on the controller’s keypad, to indicate that you want to copy the source instance into all of the other instance of this type of data in the controller.

Or you can copy into all instances up to the instance you specify. You do this by entering the letter ‘C’ in the Copy To field, followed immediately by the number of the instance. So if I wish to copy the data from Phase 1 into Phases 2 through 12, I would enter ‘C12’ in the Copy To field.

To provide another concrete example of the Copy Data function, let’s go back up to the Coordination option on the Actuated Data menu. This presents a Coord Data menu, where we can choose to copy either pattern data or split data. Let’s choose PATTERN. (MAIN MENU > 3.SYSTEM MAINTENANCE > 2.COPY DATABASE DATA > 1.ACTUATED > 2.COORD)

COORD DATA 1.Pattern 2.Split

Figure 160 – Copying Coord Data menu

This results in a display that is very similar to the one we saw before for Phase data. (MAIN MENU > 3.SYSTEM MAINTENANCE > 2.COPY DATABASE DATA > 1.ACTUATED > 2.COORD > 1.PATTERN)

As you can see from the hint text on the screen, we can copy any single defined Pattern instance into one or all 48 of the other Pattern instances, or into all patterns up to the instance we specify.

All of the copy data screens function in this same way, across all types of data, including Actuated Detector and TOD Schedule instances, to Pretimed Timing Plans, Signal Plans, and Preemption definitions.

Diagnostics Mode The Enter Diagnostics Mode option on the System Maintenance menu is used to enter a special mode of the ATC controller that allows you to troubleshooting the operation of the hardware and firmware, as well as load new firmware and restart the controller.

Caution Entering Diagnostics mode will automatically place the

intersection into Flashing operation, and will require a controller power down and restart to exit.

When you select the option, you will be given the option to cancel out of the operation in order to avoid placing the intersection into Flash.

Chapter 6 — Coordinated Operation

182 ATC-1000 Advanced Traffic Controller

GENERAL OVERVIEW OF COORDINATION

Coordination of traffic signals is a term used to describe a process in which two or more intersections are synchronized so that vehicles can pass through each intersection without stopping. Coordinated Operation is then a system mode of traffic management. Each controller within the system will operate with a cycle length, offset and split (set of phase allocations). The cycle length will typically be at any one time common to all intersections in the coordinated system, but each intersection will use its own offset and split.

Intersections set up this way will establish what is called progression of signals. There are three basic types of coordinated progressions. For example, consider the following 4 intersections with the indicated progressions.

Figure 164 – Three types of coordinated progression

Differences in the offset values of each intersection determine the type of progression. In order for synchronization and therefore the progression to be a continuous process, the return to the main street green of each intersection must be on a cyclical basis. This cycle, or time to serve all phases, must be the same as, or a multiple of, the common cycle for all intersections within the system. A technique called “double cycling” is sometimes used such that multiphase intersections might use a 90 second cycle while

Signal Timing in a Coordinated Environment

ATC-1000 Advanced Traffic Controller 183

the 2 phase intersections use 45. Each 2 phase intersection then cycles twice for each one multi-phase cycle.

SIGNAL TIMING IN A COORDINATED ENVIRONMENT

The terms defined in the following section explain how coordination is achieved across multiple intersections, each being timed by its own controller unit.

Cycle Length The cycle length is the total time to serve all phases, i.e. the time from the start of phase n green until the next start of phase n green. All intersections coordinated at any one time must use the same cycle length or a multiple thereof.

Local Cycle This term refers to the cycle timer active in each unit that actually controls phase timing. This differs from the Master Cycle, which is used as a common reference, but does not control phase timing. The zero point of the local cycle is then referenced to the master cycle by an offset value. The offsets at each intersection may differ, but the master cycle zero point should be the same for all.

The first two intersections in the system for the inbound progression are shown below. Both intersections have the same local cycle length (90 seconds).

Figure 165 – Two intersections with the same Local Cycle length

Split (Phase Allocation) A split plan is the allocation of times within the cycle for each phase. The sum of all of these split times, including the green, pedestrian, yellow, and red intervals, creates the full cycle time. Note that the splits of the various intersections that make up a coordinated corridor do not need to be the same. In the above example, the number of phases and the split times of intersection #2 are not the same as intersection #1. But since both have the same full cycle length, synchronization can still be accomplished.

Chapter 6 — Coordinated Operation

184 ATC-1000 Advanced Traffic Controller

Local Cycle Reference Point Each intersection has a reference point within its local cycle that has to remain synchronized with a master reference. This master reference is transmitted throughout the entire coordinated corridor, keeping all of the intersections in sync. Usually the local reference point for each intersection is the start or end of the Main Green phase. That is the point that is used to reference to the master reference signal.

Figure 166 – Local Cycle Reference Point

Master Cycle This cycle issues the common reference signal and therefore establishes synchronization between all of the intersections in the coordinated corridor.

Reference point... End of Main Street Green (φA).

Signal Timing in a Coordinated Environment

ATC-1000 Advanced Traffic Controller 185

Offset An offset determines where the local reference at each intersection (beginning or end of coord phase green) should occur relative to the common master cycle. For example, for the inbound offset, intersections 1 and 2 would be set up as follows:

Figure 167 – Example of Coordinated Intersection Offsets

Intersection #1 has zero offset. It is the intersection from which all others are referenced. The end of its phase A (main street) occurs at the same time as the master cycle zero point.

Intersection #2 is offset 7 seconds to allow for travel time. The end of its phase A (main street) occurs 7 seconds after the master cycle zero point.

Each successive intersection has a unique offset value as determined by the travel speed and distance.

Chapter 6 — Coordinated Operation

186 ATC-1000 Advanced Traffic Controller

SYNCHRONIZATION METHODS

Historical Sources of Sync Pulses The traditional master cycle used for referencing in years past was a 3-second pulse of zero volts from a 115VAC signal via a hardwire interconnect. All intersections would reference and synchronize themselves to these "Sync Pulses” as generated by a master dial unit. Over the years, however, other methods of providing referencing sync pulses have been incorporated and have for the most part replaced the 115VAC hardwire interconnect.

One of the more popular methods today is Time Based Coordination in which there is no interconnect at all, but each controller internally generates its own master cycle based on its internal clock and the time of day. This is a very popular technique because no interconnect system has to be installed.

Another method is through a communications link such as 2 twisted pair wire, radio, or fiber optics. Under such communications links, far more sophisticated information can be passed to and from each intersection, not just simple sync pulse commands.

Offset Seeking The local cycle timer is not always at the proper offset relative to the master cycle. It can be “out of step” upon system start-up, if cycle or offset changes are made, or after preemption. Offset seeking describes the process of getting the local cycle back into step with the master cycle. The local cycle can either time a percentage faster, slower, or stop until the proper reference is achieved.

Each method avoids abruptness, so as not to disrupt traffic. Offset seeking can sometimes take five cycles to get back in step. This seeking process is necessary to ensure a smooth transition from one pattern to another without skipping, over-timing or short-timing phases.

Coordination of an Actuated Controller Unit

ATC-1000 Advanced Traffic Controller 187

COORDINATION OF AN ACTUATED CONTROLLER UNIT In this discussion of Coordination thus far, no mention has been made of the various types of controllers, specifically pre-timed controllers versus actuated controllers. In a pre-timed controller the cycle length is fixed and does not vary from cycle to cycle. Thus, if any point within the cycle is synchronized, the entire cycle must be synchronized as well. Therefore, to synchronize a pre-timed controller, one need only to worry about the synchronization process (offset seeking) and the cycle length selection of each controller.

When an actuated controller is considered, however, just the establishment of a cycle length is a considerable process in itself. This is because the cycle length of an actuated controller will normally vary from cycle to cycle depending on vehicle demand. A cycle length must then be artificially imposed on an actuated controller to achieve coordinated operation.

To accomplish this, there are certain functions that the controller uses, such as permissive periods, holds, and force offs. These functions force the controller to operate within the constraints of a background cycle while still allowing the controller to operate in the actuated mode and allowing basic intervals such as initial (minimum) greens, walk, ped clear, yellow, red, etc., to time normally.

Functions Used to Coordinate an Actuated Controller HOLD - Holds the coordinated phase (main street) during a specific period of the cycle (when no permissive periods are active.)

PERMISSIVES - Allow a "window of time" in which the phase can be serviced. Permissives have a “start” and “end” time, and prevent a phase from being serviced too late to be properly forced off. A phase cannot be forced off during its initial (minimum) green or ped timing, thus the permissive must take this into account, i.e. a given phase permissive will end sufficiently before the force off so that if the phase is serviced, it will be able to time at least its initial green and/or ped before force off occurs.

FORCE OFF - Terminates a phase at the designated point in the background cycle. Note that Force Off is a rather mild command and can only terminate an actuated green that has timed past the Initial or ped times. It cannot force out of initial, walk or ped clear. It has no effect on yellows or reds.

It is important to note that the coordinator only uses the above commands to constrain the controller phasing and phase next decisions. It does not interfere with or modify intervals such as minimum greens, walk, ped clear, yellow, red, etc. This is a common misconception.

Chapter 6 — Coordinated Operation

188 ATC-1000 Advanced Traffic Controller

Example of Force Off And Permissive Placement This example shows how an actuated controller may be set up using the Force Off and Permissive functions in an 8 phase dual ring.

Shown is a 90 second “background” cycle with the typical placement of “fixed” force offs and permissives. Each force off establishes the point at which the phases will be terminated and move on.

Phases can “gap-out” before they “force off”. If a phase does gap out, the next phase can get more time. Notice that each permissive ends somewhat before the force off for the indicated phase pair. Under full demand on all phases, permissives generally don’t do much. However, under light demand, particularly if the coordinated phase is likely to “rest” or if other phases are likely to be skipped (no demand), permissives make sure that phases are only allowed service at such a point that they can be forced off at their designated time.

Figure 168 – Typical placements of fixed force offs and permissives

Coordination of actuated controllers can be tricky business. Two seemingly contradictory concepts are employed at once. On the one hand, because the controller is actuated, the benefits associated with an actuated controller are desired, i.e. a controller that is responsive to traffic, skips phases with no demand, varies the green appropriately for phases with demand, and finally, one that rests in the main street in absence of any demand. On the other hand, to accomplish coordination, one must constrain the timing so that the controller operates within the confines of the background cycle.

Coordination of actuated signals is often a complex matter, and requires a great deal of effort on the part of the responsible agency to provide the analysis (traffic studies, etc.) required for proper programming and subsequent operation.

Coordination of actuated signals can often be controversial as well. This is primarily due to the nature of their operation. In the case of pre-timed controllers, signal progression tends be well behaved and each signal “nicely” displays its green in just the proper order. Actuated signals, however, do not always seem to behave so nicely. For example, if at a given intersection, all the side street phases do not use all their green time (they "gap-out" before they "force off"), then there will be an "early return" to the main street.

Coordination of an Actuated Controller Unit

ATC-1000 Advanced Traffic Controller 189

The "platoon" of vehicles at that intersection will then be released and may arrive at the next intersection too early, before the green appears. These vehicles will have to stop, which, of course, defeats the purpose of coordination.

There are, however, a couple of things to consider relative to this issue. Firstly, despite the lack of appearance of coordination under such circumstances, the system may actually be more efficient. Even though the pre-timed system may be well coordinated, it often does so by arbitrarily holding the main street red as the side streets are provided with a fixed duration green time, whether needed or not. Conversely, the actuated machine returns to the main street as soon as it can. Since some main street vehicles may turn off before they reach the next intersection, an early return is certainly beneficial to them. For those that proceed through the next intersection, although they may be hampered by arriving too early, they may also have the luck that the next intersection returns to main street early as well, and can proceed unimpeded. This type of operation provides maximum efficiency although it can occasionally appears sporadic and unpredictable.

This leads to the second point: proper coordination using actuated controllers requires that the responsible agency provides the proper cycle and split settings for the level and distribution of traffic at any given time of day. If the cycle length and split times are appropriate for the conditions at all times of the day, non-beneficial early returns to the main street can be minimized.

PROGRAMMING A PEEK ATC CONTROLLER FOR COORDINATION

Coordination Parameters Explanation All Peek ATC Series Controllers are compliant with NTCIP 1202, v02.18, therefore the programming parameters must follow the NTCIP Object designs. The NTCIP design structure is very conducive to interoperability with NTCIP Central Systems. However, NTCIP cannot be described as user-friendly when programming a complex function such as Coordination. This document will assist the end-user in the organization of parameters to make programming Coordination an easier task.

This document should be utilized in conjunction with the ATC-1000 Manual that can be downloaded off the Peek website at the following link: http://www.peektraffic.com/ptmanuals.htm.

The recommendations provided in this guide will be given in a format conducive with the organization needed to operate the ATC Series Controller in Coordination and possibly in conjunction with Traffic Responsive or even Adaptive Control. The recommended format organization is not mandatory for Coordination, but could be required for Traffic Responsive or Adaptive control.

Coordination control has been historically programmed in sets of Cycle(s), Offset(s) and Split(s), or COS. NTCIP controls Coordination in Patterns, as defined in NTCIP Object 2.5.7, cited below.

Programming a Peek ATC Controller for Coordination

ATC-1000 Advanced Traffic Controller 191

An NTCIP Pattern consists of the Pattern Number, Cycle Time, Offset Time, Split Number and Sequence Number. The NTCIP Pattern Number permits Pattern Numbers from 1 to 255. Pattern Number 254 is reserved to call Free Operation. Pattern Number 255 is reserved to call programmed Flashing Operation.

The ATC Series Controller currently supports Pattern Numbers 1 through 48, for NEMA Coordination. Pattern Numbers 49 through 253, are either reserved or dedicated to pre-timed or interval control Coordination.

The ATC Series Controller complies with the NTCIP limitation on Cycle Lengths in whole seconds from 30 to 255 Seconds. Offset values are in whole seconds from 0 to 254. Split Numbers are derived from NTCIP specified Split Table. The ATC Series Controller supports 16 Splits within the NTCIP Split Table. Sequence Numbers are derived from the NTCIP specified Sequence Table. The ATC Series Controller supports 16 Sequences.

Parameter Value Organization The end-user should now start the organization of parameters to assist in parameter entry into the ATC Series Controller. Since the Pattern Number quantity is currently limited to 48. A decision needs to be made on the use of Cycles, Offsets and Splits. Historically most traffic personnel have utilized three or five Offsets which support the Inbound Flow, Outbound Flow and a Balanced Flow to varying degrees. In this example three Offsets will be utilized. Splits are most commonly programmed as Balanced between the Main Street and Side Street, Slightly Favoring the Main Street, Moderately Favoring the Main Street and Heavily Favoring the Main Street. This example will use four Splits per Cycle. This permits the use of four different Cycle Lengths within the constraint of 48 Patterns.

4 Cycle Lengths x 3 Offsets x 4 Splits = 48 Pattern Numbers

On the attached Excel Spread sheet, record the four Cycle Lengths in whole seconds between 30 and 255 seconds.

Using a Modeling Program calculate Offsets for each Cycle Length for Inbound, Balanced and Outbound. Enter these values on the attached Excel Spreadsheet.

Calculate splits by Phase to the whole second. The sum of each Ring’s assigned Phases Split Times must equal the cycle length. Calculate the four Splits (Balanced between the Main Street and Side Street, Slightly Favoring the Main, Moderately Favoring the Main Street and Heavily Favoring the Main Street) for each cycle length and enter them on the attached Spreadsheet.

If more than one sequence is used at this intersection, then enter the Sequence Number and a quick representation of the sequence on the attached Excel Spreadsheet. A change in sequence over the course of the day is rare. One example would be a Lead/Lag Intersection that changes the Lead Phase by Time of Day (TOD).

198 ATC-1000 Advanced Traffic Controller

EXAMPLE: PROGRAMMING OF COORDINATION

This section describes how to program the Coordination portion of the ATC-1000 database using both IQ Link and the front panel keypad and screen.

1. To start the process, we’ll begin in IQ Link. Open IQ Link, by inserting the correct User Name and Password, then click the OK button. (The default user name and password are ‘USTC_ADMINISTRATOR’ for both.) The main IQ Link screen will open, as shown below:

Figure 183 – IQ Link window

2. Quickly click on the third button from the left., which is the ‘Stop/Start Automatic Polling’ button (It has concentric circles and is red and green. shown at right) Pressing this button will stop communications attempts until the user has selected an Intersection and is ready to communicate with that Intersection.

3. An ATC-1000 intersection will need to be added to the IQ Link database first. Select Database Edit from the Intersection menu.

Figure 184 – Database Edit command on the IQ Link Intersection menu

This will bring up the Intersection List window, as shown in Figure 185.

Example: Programming of Coordination

ATC-1000 Advanced Traffic Controller 199

Figure 185 – Intersection List window

4. Select the New Intersection button from the Intersection List window toolbar (shown at right). The following dialog box will appear, for the entry of a new intersection controller:

Figure 186 – Controller Configuration dialog box

5. Enter an Intersection Name in the space provided. (The Default listing of Name0 can be used if you don’t have a more specific name in mind.) The name can be up to 50 characters in length and can include spaces and punctuation. For ease of use, it’s better to keep the name under 30 characters. We’ll name our controller ‘Test’ throughout the rest of this tutorial.

6. Enter the Cabinet Address, which is a four digit hexadecimal number. It must be a unique number within the IQ Link database. For networks similar to the one used in New York City municipal traffic controller cabinets, the cabinet address is supplied by hardware located within each cabinet and must be set here to match the intended cabinet location. In other network setups, IQ Link just uses the ‘Cabinet Address’ value that is stored within the ATC-1000. It uses this address as a unique device identifier for communications purposes. We’ve entered the number ‘019D’ as our cabinet address.

a.) The Cabinet Address that is stored in the ATC-1000 can be viewed (or edited) by pressing the MNU (Menu) button on the front panel of the controller to bring up the controller’s menu system. Then press 2 to enter the Programming menus. Then press 1 to enter Unit Configuration, then 5 to see the COMMS AND I/O SET-UP menu, and finally 3 to open the IP/CABINET ADDRESS screen. (See Figure 187)

7. Back in the IQ Link Controller Configuration dialog box, you should check the Pretimed Intersection box only if this ATC-1000 will be programmed as a Pretimed controller (rather than as a NEMA phase-based controller.)

Example: Programming of Coordination

ATC-1000 Advanced Traffic Controller 201

Note The ATC-1000 is currently the only controller in the world that can be programmed as either a NEMA or a pretimed controller.

8. Click the OK button to accept the Controller Configuration in IQ Link. Now that this controller information has been entered into IQ Link, the Intersection Name will appear in the Intersection List window, as shown below:

Figure 189 – Intersection List

9. Make sure the new controller is highlighted in the Intersection List window, and click the Intersection Button. This will load this Intersection for database programming, as displayed below.

10. After clicking the Intersection Button, the Select Intersection screen will appear within the Intersection List SubMenu. Highlight the desired Intersection, check the Connect to Controller box, enter the correct System IP Address, check the method of communication of Ethernet or Serial and click the OK Button.

11. Refer back to the ATC-1000 screen and the IP/Cabinet Address Setup screen. The four sets of three digits shown next to IP Address SYSTEM is the ATC-1000’s Ethernet (or ‘IP’) Address. An example would appear as IP Address System: 010.120.001.157.

NTCIP Object 2.5.1 states that the Coord Operational Mode Parameter as: “This object defines the operational mode for coordination.” The NTCIP possible modes are:

Chapter 6 — Coordinated Operation

204 ATC-1000 Advanced Traffic Controller

Value Description 0 Automatic - this mode provides for coord operation, free and flash to

be determined automatically by the possible sources (i.e. Interconnect, Time Base, or System Commands).

1-253 Manual Pattern - these modes provides for Coord operation running this pattern. This selection of pattern overrides all other pattern commands.

254 Manual Free - this mode provides for Free operation without coordination or Automatic Flash from any source.

255 Manual Flash - this mode provides for Automatic Flash without coordination or Free from any source.

These definitions are also listed on the bottom of the IQ Link Coordination submenu for each subsequent parameter.

16. Back in IQ Link, to run the ATC-1000 in Coordination, select 0 for Automatic in IQ Link as shown below or keypad, in Edit Mode, the value 000 and ENT Buttons, as shown above.

Figure 196 – Setting Coord Operational Mode in IQ Link

NTCIP Object 2.5.2 for Coord Correction Mode Parameter has the definition “This object defines the Coord Correction Mode.” The possible modes are:

other: the coordinator establishes a new offset by a mechanism not defined in this standard.

dwell: when changing offset, the coordinator shall establish a new offset by dwelling in the coord phase(s) until the desired offset is reached.

shortway (Smooth): when changing offset, the coordinator shall establish a new offset by adding or subtracting to/from the timings in a manner that limits the cycle change. This operation is performed in a device specific manner.

Example: Programming of Coordination

ATC-1000 Advanced Traffic Controller 205

addOnly: when changing offset, the coordinator shall establish a new offset by adding to the timings in a manner that limits the cycle change. This operation is performed in a device specific manner.

The Coord Correction Mode Parameter was previously known in legacy Peek family of Controllers as Offset Seeking. The method in which each of these modes work is describes as follows:

Dwell Coord Correction Mode (Offset Seeking) allows the Controller to rest in the coordinated phase(s) continuously until the new offset point is reached. Dwell mode is similar to the technique electro-mechanical Controllers used to get in step and is not widely used anymore.

Shortway Coord Correction Mode (Offset Seeking) moves Local Zero to the offset by a process that either shortens or lengthens the cycle time by 17 and 20 percent, respectively – whichever achieves sync fastest. The +20% long or –17% short is evenly distributed among all phases in the cycle. Because it can seek in either direction, the most out-of-sync the unit can be is 50% of the cycle. The unit accomplishes this by actually timing either 0.83 or 1.2 seconds for each real time second in the cycle that elapses until the new offset is reached. Although similar in operation to Add Only, the ability to shorten the cycle can considerably speed up the seeking process. For example, the Local Zero point arrives a few seconds late relative to where it should be. With dwell or addOnly, since the cycle can only be increased, the unit has to essentially seek “all the way around” the cycle to get in step. With short route, it can simply speed up the cycle for a brief period and get in step quickly.

Add Only Correction Mode (Offset Seeking) moves Local Zero to the offset by lengthening the cycle only. This is accomplished by actually timing 1.2 seconds for each second in the cycle that elapses until the new offset is reached (local times slow). This represents a 20% increase in cycle time and is evenly distributed among all phases in the cycle. Because the seeking is in one direction only, it may take up to five cycles to get in sync. Phases can only time longer and never shorter than their allocation time.

Short route is generally preferred in most cases, but addOnly may be preferred when phase timing is critical, as with long pedestrian times.

If the Coord Correction Mode Parameter is set to other(1), a proprietary Coord Correction Mode developed for the City of Toronto, Canada is available by programming the USTC Coord Correction Mode. The possible modes are:

Toronto – defines a percentage of the current cycle length that determines if time should be added or subtracted to splits when establishing a new offset based on how late or early the coordinated phase begins.

Other – option selected when Coord Correction Mode Parameter is set to dwell(2), shortway(3) or addOnly(4).

20. To select the USTC Coord Correction Mode using IQ Link, select the recommended other(1) as shown below.

Figure 200 – Setting Coord Correction Mode

NTCIP Object 2.5.3 states that the Coord Maximum Mode Parameter defines the Coord Maximum Mode. The possible modes are:

other: the maximum mode is determined by some other mechanism not defined in this standard.

maximum1: the internal Maximum 1 Timing shall be effective while coordination is running a pattern.

Chapter 6 — Coordinated Operation

208 ATC-1000 Advanced Traffic Controller

maximum2: the internal Maximum 2 Timing shall be effective while coordination is running a pattern.

maxInhibit: the internal Maximum Timing shall be inhibited while coordination is running a pattern.

In Coordination, each programmed Phase can terminate in three manners. If the Minimum Green timing has been completed and the Extend timing for that Phase’s Detector has reached zero, the Phase will Gap Out. If the Extend timing stays active for that Phase’s Detector and extends the Phase out to the Maximum Timings in effect (Maximum 1 or Maximum 2), the Phase will Max Out. If the Extend timing stays active for that Phase’s Detector and extends the Phase to the limit of its programmed Split, then the Phase will Force Off. If the Maximum Timings in effect (Maximum 1 or Maximum 2) are shorter than the programmed Split, and the Maximum is not inhibited, then the Phase will terminate by Max Out spoiling the efficiency of Coordination. If the Maximum Timings in effect (Maximum 1 or Maximum 2) are shorter than the programmed Split, and a Force Off is desired, then maxInhibit should be selected. If all the Maximum Timings in effect (Maximum 1 or Maximum 2) are longer than all the programmed Splits, and a Force Off is desired, then maxInhibit is not required to be selected. This may be an advantage, if the Controller is programmed for Free Operation part of the day and Coordination for part of the day. The recommended mode is to activate Coord Maximum Mode Parameter of maxInhibit during Coordination.

21. Set the Maximum Mode on the ATC-1000 to the value 4. maxInhibit, as shown below.

2.3.1 COORD VARIABLES PG1OF1 OPERATIONAL MODE......000 (0-255) CORRECTION MODE.......shortway(3) USTC CORRECTION MODE..other(1) MAXIMUM MODE..........maxInhibit(4) FORCE MODE............fixed(3) SYSTEM PATTERN........000

Figure 202 – Setting the Maximum Mode in IQ Link

NTCIP Object 2.5.4 states that the Coord Force Mode Parameter is the object that defines the Pattern Force Mode. The possible modes are:

other: the controller implements a mechanism not defined in this standard.

floating: each non-coordinated phase will be forced to limit its time to the split time value. This allows unused split time to revert to the Coordinate phase(s).

fixed: each non-coordinated phase will be forced at a fixed position in the cycle. This allows unused split time to revert to the following phase/phase pair.

Force Offs are applied by the Coordinator to terminate a Phase/Phase Pair, if the Phase has not already terminated due to a Gap Out or a Max Out. If the Yield Point in the cycle (Local Zero) is referenced to the End of Main Street Green, then the Main Street Force Off is calculated to occur at the Cycle Zero Point. If the Yield Point is referenced to the Beginning of Main Street Green, the Main Street Force Off will be calculated as cycle zero + (main street split - main street clearance). In the Fixed Pattern Force

Mode, Side Street Force Off Points are then computed sequentially from the Coordinated Phase/Phase Pair Force Off Point. In the Floating Pattern Force Mode, the Force Off’s are more like Max times.

This decision should be based on which provides maximum benefit to the intersection. If the best thing to do is give the Main Street every unused second, then choose Floating Pattern Force Mode. If the best thing to do is give the Side Street, especially thru’s, any extra time that might occur from skipped phases or early Gap Outs, then use Fixed Pattern Force Mode. Phase Max Time settings

Chapter 6 — Coordinated Operation

210 ATC-1000 Advanced Traffic Controller

also play an important role in Phase timing during Coordination. If the Max Time in effect for a Phase during Coordination is about the same as its Split, then the operation will be much like Floating Pattern Force Mode on, even if Fixed Pattern Force Mode is programmed. This is because if the Phase starts early, it will Max Out before being Forced Off, unless it is a Coordination Phase. With Fixed Pattern Force Mode enabled, without the Max Timer influencing termination, a Phase that starts early with no Gap Out will use all of the unused time from the previous Phase/Phase Pair. This leaves none of the unused time for subsequent Non-coordinated Phases/Phase Pairs. A Phase’s Max Time can be used to control the distribution of unused time to subsequent Non-coordinated Phases/Pairs, where Coord Maximum Mode maxInhibit is not used.

22. Set Force Mode on the ATC-1000 to option 3. fixed, as shown in Figure 203.

NTCIP Object 2.5.14 states that the System Pattern Control parameter defines this object as used to establish the Called System Pattern/Mode for the device. The possible values are:

Table 21 – System Pattern – Available Values

Value Description 0 Standby - the system relinquishes control of the device.

1-253 Pattern - these values indicate the system commanded pattern

254 Free - this value indicates a call for Free 255 Flash - this value indicates a call for Automatic Flash

If an unsupported / invalid pattern is called, Free shall be the operational mode. The device shall reset this object to ZERO when in BACKUP Mode. A write to this object shall reset the Backup timer to ZERO.

This object/feature allows the end-user to operate an ATC-1000 in a local environment and impose programmed System Patterns. One use for this feature is to test the operation of a newly programmed Pattern Number in an ATC-1000 connected to a Light Board, or in a cabinet that is not connected to a Central System.

The ATC-1000 uses a dynamic or “auto-calculation” method to manage Permissive (windows). The method is hard-coded and currently not selectable. The ATC-1000 uses a hybrid permissive combination of a 5% Yield, on the Coordinated Phases and a Multiple Permissive style on the Non-Coordinated Phases. Permissive Periods are not applied to Coordinated Phases. Each Coordinated Phase has a pre-calculated Yield Point. This Yield Point occurs when Hold drops and Force Off activates, allowing the Coordinated Phase(s) to advance to ped clearance if CNA is applied, or yellow clearance if no CNA and permitted conflicting call(s) exist.

Example: Programming of Coordination

ATC-1000 Advanced Traffic Controller 213

Actuated Phase Yield Point = split end point - (yellow + red clearance)

CNA Phase Yield Point = actuated phase yield point - ped clearance time

The Yield Window opens at the first Coordinated Phase Yield Point. The Yield Window closes at the last Coordinated Phase Yield Point, plus the 5% yield time. If a Coordinated Phase advances at its Yield Point, the Multiple Permissive style calculates Phase N's vehicle permissive period terminations when insufficient time is remaining to terminate all Conflicting Phases and run Phase N's Initial/Min Green time prior to Phase N's fixed force off point. The Pedestrian permissive period terminates when insufficient time is remaining to terminate all Conflicting Phases and run Phase N's Walk plus Ped Clear time prior to Phase N's fixed force off point. Because the possibility exists that phases have unequal yellow, red and ped clear times, the permissive period terminations update when a phase state change occurs. The mathematical formulas are:

EndVehPermissive = FixedForceOff - MinGreen - (VehClearFactor + PedClearFactor);

EndPedPermissive = FixedForceOff - PedTime - (VehClearFactor + PedClearFactor;

MinGreen is defined as the larger of the phase's Initial/Min Green time and Max Initial time, if Volume Density is active to ensure a proper force off with the extra Min Green. PedTime is the smaller of the phase's Walk + Ped Clear and (Split - Yellow - RedClear) to ensure a long enough permissive period, if the ped time is greater than split time. VehClearFactor is the largest conflicting green phase's yellow + red clearance time. PedClearFactor is the largest conflicting CNA green/walk phase's ped clearance time.

Note VehClearFactor and PedClearFactor add separately because conflicting ped clearances finish prior to conflicting greens going yellow.

The following are three scenario examples of how the permissive algorithms work:

Calculating EndVehPermissive for Phase 1 -- Phase 1's FixedForceOff = 50.

Phase Times:

Phase 1 2 3 4 5 6 7 8 MinGreen 10 10 10 10 10 10 10 10 Yellow 5 4 6 3 3 3 4 3 RedClr 0 1 1 3 4 3 2 2 PedClr 0 10 0 8 0 16 0 5

Scenario 1:

• Phase 3 is green

• Phase 8 is in CNA green/walk • VehClearFactor = ph 3 y+r = 6+1 = 7

ph 8 y+r = 3+2 = 5 max[7,5] = 7

• PedClearFactor = ph 8 ped clear time = 5 max[8] = 5

• EndVehPermissive phase 1 = 50 - 10 - (7 + 5) = 28

Scenario 2:

• Phase 3 is green • Phase 8 is in CNA green/pclr • VehClearFactor = ph 3 y+r = 6+1 = 7

ph 8 y+r = 3+2 = 5 max[7,5] = 7

• PedClearFactor = 0 (no CNA walks conflicting with phase 1) • EndVehPermissive Phase 1 = 50 - 10 - (7 + 0) = 33

Scenario 3:

• Phase 3 is yellow/4 next • Phase 8 is in CNA green/pclr • VehClearFactor = ph 8 y+r 3+2 = 5

= max[5] = 5 • PedClearFactor = 0 (no CNA walks conflicting with phase 1)

• EndVehPermissive phase 1 = 50 - 10 - (0 + 5) = 35

Example: Programming of Coordination

ATC-1000 Advanced Traffic Controller 215

Pedestrian Override Mode (POM) There is no programming for POM. This proprietary feature is automatically activated by entering coordination data in the ATC-1000. When POM is active and an actuated ped is serviced, the local cycle counter is ‘frozen’ at the force off point of that phase until the end of the pedestrian clearance interval. Then the counter resumes timing from where it left off and the ATC-1000 immediately begins Correction Mode selected offset seeking until it gets back into step. POM allows the coordinator to run a pattern that has an actuated ped phase that is longer than the time allocated to the phase. POM is typically used for any actuated Ped that is extremely low volume (less than two actuations her hour). The split plan timing then is set-up for normal vehicular demand and does not take into account ped timing. When the occasional ped occurs, the cycle timer stops to accommodate it, a late return occurs, then offset seeks to get in step. Ped Override will be ON if (Walk + Ped Clearance + Yellow + Red) is greater than the Phase Split.

Note POM works best when Short Route Correction Mode (Offset Seeking) is selected. Small offset errors can be corrected within one cycle.

When all requisite Coordination parameters are entered and a Pattern is selected and activated, an internal Coordination Plan Check is executed. The following checks are run for validity before the coordinator will start:

1. Cycle time cannot be less than 30 seconds. If the cycle length is less than 30 seconds, then an INVALID_CYCLE_TIME error will occur.

2. Coordinated Phases must be mutually compatible. If the Coordinated Phases are not compatible, then a COORD_PHASES_NOT_COMPATIBLE error will occur.

3. A Coordinated Phase must be in each utilized ring, when possible. For example, in an 8-Phase Quad Left intersection with Phases 7 and 8 omitted, Phase 2 cannot be designated as the only the Coordinated Phase or an error will occur, unless Phase 6 is designated as a Coordinated Phase in Ring 2. However, it is satisfactory for either Phase 3 or 4 to be the only Coordinated Phase, because there is no eligible Phase in Ring 2 compatible with Phase 3 or 4. If only one Coordinated Phase is selected and there is a programmed compatible Phase available for selection and no selected in each Ring, then a NO_COORD_PHASE_IN_RING error will occur.

4. The sum of the Co-Phase Group splits must be less than or equal to the cycle length. If the sum is less than the cycle length, the extra time goes to the Coordinated Phases, as required by NTCIP Object 1.1.1.1 Split Time Parameter. Co-Phase Groups are logical groupings of phases (Co-Phase 1 = Phases 1, 2, 5 & 6; Co-Phase 2 = Phases 3, 4 ,7 & 8) that determine whether Phases in different Rings are compatible or conflicting. Phases in different Rings and in different Co-Phase Groups are conflicting. Phases in different Rings and in the same Co-Phase Group are

Chapter 6 — Coordinated Operation

216 ATC-1000 Advanced Traffic Controller

compatible. If the sum of the Co-Phase Group splits is not less than or equal to the cycle length, then a SPLIT_SUM_GREATER_THAN_CYCLE_TIME error will.

5. The sum of each Co-Phase Group splits by Ring must be equal. In an 8-Phase Quad Left intersection, the splits of Phases 1 + 2, must equal Phases 5 + 6; and Phases 3 + 4, must equal Phases 7 + 8. If the sum of each Co-Phase Group splits by Ring is not equal, then a COPH_RING_SPLIT_SUMS_NOT_EQUAL error will occur.

Definition A Barrier Phase is the last phase in each concurrency Group in each Ring. In a standard 8-phase, 2-ring sequence, phases 2,4,6, and 8 are Barrier Phases.

6. Phase Minimum Green Check. An INIT_GREATER_THAN_PHASE_SPLIT error will occur if: a) Each non-Barrier phase’s Initial/Min Green + Yellow + Red Clear is greater than the Split Time, OR b) Each Barrier phase’s Initial/Min Green + (largest Yellow + Red Clear sum of the Concurrency Group’s phases) is greater than the Split Time.

7. Phase Minimum Pedestrian Check. A PED_TIME_GREATER_THAN _PHASE_SPLIT error will occur if: a) Each CNA non-Barrier phase’s Walk+Ped Clearance + Yellow + Red Clear is greater than the Split Time, OR b) Each CNA Barrier phase’s Walk+Ped Clearance + (largest Yellow + Red Clear sum of the Concurrency Group phases) is greater than the Split Time.

Note An actuated Pedestrian Phase always uses POM because there is no NTCIP Object to activate it.

8. A Trail or Trailing Overlap is the NTCIP Object feature commonly known as a Double Clearing Overlap. A Trail (or Trailing) Overlap yellow + Trail Overlap red + Parent Phase initial/min green must be less than or equal to the Parent Phase’s split time. For example, Phase 1 is a Parent Phase for Overlap A, which is a Trail Overlap. Phase 1’s split = 20 seconds. Phase 1’s initial/min green = 10 seconds. A TRAILING_OVERLAP_SPLIT_ERROR error will occur, if Overlap A’s programmed trail yellow + trail red is greater than 10 seconds.

9. The Offset time for each Cycle cannot be greater than the cycle time. If cycle length is 100 seconds and Offset for 110 seconds is entered, it will use an offset of 10 seconds, and an OFFSET_TIME_GREATER_THAN_CYCLE_TIME error will occur.

Example: Programming of Coordination

The dynamic display reads Bad Plan-> X, where X is one of the nine errors listed above. If more than one error is found, only one error will be displayed at one time. All errors must be cleared for the ATC-1000 to enter Coordination.

The Coord Pattern Status, Local Free Status, Coord Cycle Status (Seconds) and Coord Synch Status (Seconds) on the Mode/Status/Control Tab of the Coordination Window submenu will be explained after the Pattern Table and Split Table Tabs are discussed below, so operating Coordination will display status seen during normal Coordination operation.

Chapter 6 — Coordinated Operation

218 ATC-1000 Advanced Traffic Controller

Programming the Pattern Table for Coordinated Operation To start programming the Pattern Table of the Coordination Window, place the cursor on the Tab and left mouse click. The Pattern Table should appear as below:

Figure 208 – Pattern table in the Coordination window of IQ Link

A Pattern, as defined by NTCIP, consists of one Cycle time (length in seconds), one Offset time, one Split table number and a sequence number (i.e. for lead-lag adjusting). The Maximum Patterns Parameter is a read-only NTCIP object. IQ Link displays several read-only NTCIP Objects. These read-only NTCIP Objects are displayed in IQ Link only to show the capacity (i.e. maxOverlaps, maxPhases).

NTCIP Object 2.5.5 maxPatterns specifies Pattern 253 as the maximum possible Coordination value. The ATC-1000 has 48 Phase-based Patterns denoted 1 thru 48, as shown in the Coordination Window’s Pattern Table. Patterns 49-253 are for pre-timed operation or reserved for future use and not relevant to this Phase-based Coordination chapter.

NTCIP Object 2.5.5, states that the Maximum Patterns Parameter is the maximum number of Patterns this Actuated Controller Unit (ATC-1000) supports. This object indicates how many rows are in the patternTable object (254 and 255 are defined as non-pattern status for Free and Flash).

Example: Programming of Coordination

ATC-1000 Advanced Traffic Controller 219

Since the ATC-1000 supports 48 patterns, enter 48 to in the field to the left of Max Patterns, as indicated below:

Figure 209 – Setting Max Patterns in IQ Link

NTCIP Object 2.5.6, states that the object of Pattern Table Type provides information about any special organizational structure required for the Pattern Table. The defined structures are as follows:

other: The Pattern Table setup is not described in this standard, refer to device manual.

patterns: Each row of the Pattern Table represents a unique pattern and has no dependencies on other rows.

offset3: The Pattern Table is organized into plans which have three offsets. Each plan uses three consecutive rows. Only patternOffsetTime and patternSequenceNumber values may vary between each of the three rows. Plan 1 is contained in rows 1, 2 and 3, Plan 2 is contained in rows 4, 5 and 6, Plan 3 is in rows 7, 8 and 9, etc.

In the ATC-1000, this object should be currently entered as other.

Chapter 6 — Coordinated Operation

220 ATC-1000 Advanced Traffic Controller

The Pattern Table setup is not described in NTCIP, but is set up as one Pattern Cycle Time, one Pattern Offset Time, one Pattern Split Number and Pattern Sequence Number, as displayed in Figure 210.

Figure 210 – Pattern Table overview in IQ Link

The Pattern Table Type is currently hard-coded in the ATC-1000. There is no entry selection for keypad entry. The Pattern Table Type can be uploaded from the ATC-1000, as shown above.

NTCIP Object 2.5.7, states that the object of Pattern Table is a sequence table containing Actuated Controller Unit Coordination Pattern Parameters. The number of rows in this table is equal to the maxPatterns object. Parameters for a specific Actuated Controller Unit pattern are: patternNumber, patternCycleTime, patternOffsetTime, patternSplitNumber and patternSequenceNumber.

Keeping in mind that the ATC-1000 may be used in a threshold-based Traffic Responsive mode available in IQ Central, the entry of Plans should be in an organized manner conducive to Traffic Responsive Operations. For example purposes, the programming demonstrated below will consist of four progressive Pattern Cycle Time(s) or cycle lengths arranged from shortest to longest; three Pattern Offset Time(s) arranged as Inbound (I), Balanced (B) and Outbound (O); and four splits for Balanced (B), Slightly (S), Moderately (M) and Heavily (H) favoring the Main Street Coordinated Phases.

Example: Programming of Coordination

ATC-1000 Advanced Traffic Controller 221

These four split modes will follow the percentage table listed below:

Split Mode Percentage (%) by Phase Pair

1/5 2/6 3/7 4/8 Balanced 25% 25% 25% 25% Slightly 23% 29% 23% 25% Moderately 15% 35% 15% 25% Heavily 15% 40% 15% 20%

However, since NTCIP does not support entry by percentage, sixteen different splits (Split Pattern Numbers) will have to be entered to provide time in seconds parameters for four split modes over four cycle lengths. An outlined table showing this logic is as follows:

Plan # Cycle Offset Split Mode/Number Plan # Cycle Offset Split Mode/Number 1 90 I B/1 25 130 I B/9 2 90 B B/1 26 130 B B/9 3 90 O B/1 27 130 O B/9 4 90 I S/2 28 130 I S/10 5 90 B S/2 29 130 B S/10 6 90 O S/2 30 130 O S/10 7 90 I M/3 31 130 I M/11 8 90 B M/3 32 130 B M/11 9 90 O M/3 33 130 O M/11 10 90 I H/4 34 130 I H/12 11 90 B H/4 35 130 B H/12 12 90 O H/4 36 130 O H/12 13 110 I B/5 37 150 I B/13 14 110 B B/5 38 150 B B/13 15 110 O B/5 39 150 0 B/13 16 110 I S/6 40 150 I S/14 17 110 B S/6 41 150 B S/14 18 110 O S/6 42 150 O S/14 19 110 I M/7 43 150 I M/15 20 110 B M/7 44 150 B M/15 21 110 O M/7 45 150 O M/15 22 110 I H/8 46 150 I H/16 23 110 B H/8 47 150 B H/16 24 110 O H/8 48 150 O H/16

TRAFFIC RESPONSIVE OPERATION

Traffic responsive, or the arterial coordination of many intersections using a central system as the coordinator, is possible and has been configured using ATC-1000 controllers and either Peek’s IQ Central central system software, or third party central system applications. The controller will take pattern changes from the central system as the primary method of controlling Traffic Responsive operation.

This capability is described in detail in the IQ Central Operating Manual.

Chapter 7 — Pretimed Operation

230 ATC-1000 Advanced Traffic Controller

OVERVIEW

Pre-timed operation is divided into two major functions, signal plans and timing plans.

Signal Plans

There are four signal plans available. A signal plan is basically a mapping of the signals and outputs for each interval. The signal plan is the sequence of color indications for all used channel outputs that will appear on the street. The signal plan also includes minimum times for all used intervals and programmable options for each interval covering manual control, transitional control, and semi-actuation of vehicle or pedestrian.

Timing Plans

There are 32 available timing plans. Each timing plan defines how many intervals will be used in the pattern. A timing plan can use up to 24 intervals. The plan also includes a cycle length, an offset, and a set of split times, one for each of the intervals in the plan.

Plan Processing

When a pretimed pattern is in effect, the controller starts the associated timing plan, using the associated signal plan signal output assignments for the intervals. The timing plan starts at interval #1 when the controller powers up, or when a new pattern is called. When one interval ends, the next in the sequence starts automatically. Unless options have been set for manual control (such as MCE or Actuated) in the signal plan, the timing plan sequence will only pause at ‘All Red’ intervals. As an example of how the sequence may be paused in a given state, a signal plan may be configured to be ‘Actuated’ so that the interval sequence will rest on main street green until an actuation is received.

Exiting a Timing Plan Sequence

Signal plans can be exited at a specified interval so that they can transition either to another signal plan, another timing plan, or to automatic flash.

Calling the Plans But how are the pre-timed plans called into operation? It’s all based on Pattern. When a pattern number between 101 and 224 is called, either by the time of day scheduler, or by a central command or override, those pattern automatically evoke a preset Signal plan and timing plan. The assignments are hard coded in the ATC controller and follow the assignment pattern shown in Table 22.

Note These assignments are also visible on the ATC front panel interface, along with some additional information, on the Timing Plan > Signal/Offset/Split Data screen. (Main Menu > 2 .Programming > 7 .Pre t imed > 1 .T iming Plans > 1 .Cyc le / Of fse t / Spl i t Data ) However, the assignments cannot be modified on these screens.

USING THE PRETIMED PROGRAMMING SCREENS

Most of the interface and controls for the ATC-1000 have an implicit assumption that most users of the controller will be working with a NEMA style, actuated, phase-based operation in their traffic cabinets. This includes the preemption, TSP and most other parts of the interface. The Pre-timed menu is where most of the settings are located to operate the other type of traffic pattern control in the ATC-1000: pre-timed interval based, rather than NEMA phase-based. Whereas phases assume signals respond to provide traffic ‘movements’, pre-timed operation is more concerned with signal outputs.

The first 48 patterns in the controller, as well as the special case patterns 254 and 255, are the NEMA patterns. The rest of the usable patterns, 101 to 228, are pre-timed patterns, whose signal outputs and operating parameters are defined in these screens.

The table will show the currently running pattern number, along with the associated timing plan and signal plan that is currently being used to run the intersection. The table shows what timing plans and signal plans are assigned to each pattern, as well as the current values for Cycle length and offset times for each of the 32 timing plans.

Note The same timing plan data is shown four times in the table, one for each of the four signal plans.

The only value that can be entered directly on this screen is the Commanded Plan. This is the location where pretimed operation can be set directly by entering a pattern number to run. Otherwise, the pattern number is selected by time of day, or by central command.

Figure 224 – Pretimed Cycle/Offset/Split Data (Page 1)

Cycle Length — This is the length of time to complete an entire loop of the timing plan, from interval 1 to the last ‘Interval used’ in the plan, and then back to interval 1. The cycle length is calculated automatically if the Split Type is seconds or tenths of seconds. You will need to enter the cycle length manually (in seconds) if the Split Type is Percentage (“per”).

Offset — This is the offset time that this intersection will start the cycle after a new pattern is called, assuming this controller is part of a coordination plan. Pretimed coordination is based on synchronized clocks. Each intersection has the same cycle length, and each intersection switches to a new pattern at the same time of the day. This offset value then allows the intersection signals to be coordinated. This value can either be a number in seconds (0 to 254 seconds) or a percentage (0 to 100%). The units are set using the Offset Type parameter (below.)

Offset Type — Use the right arrow to navigate to this field to set the units that will be used with Offset (above). This value can be either sec (seconds) or per (percentage), which tells the ATC how to interpret the value you enetered for Offset.

Intervals used — This is the number of intervals (out of 24) that will be used in this timing plan. Even if times are entered for splits beyond this number, only the first number of splits up to this value will actually be used in the plan. So if you call for the Intervals used to be 13, then the first 13 splits in the table below are the ones that will be timed during the pretimed cycle.

Chapter 7 — Pretimed Operation

236 ATC-1000 Advanced Traffic Controller

Split Type — This is a global value, showing what units are used for all of the split times in this timing plan. The possible values are sec (seconds), ten (tenths of seconds), or per (percentage of the cycle length.)

Split Time — A three digit number for each split that represents either seconds, tenths of seconds, or percentage of cycle time, depending on what Split Type has been chosen. Valid values are between 000 and 255, so 0 to 255 seconds, 0.0 to 25.5 seconds, or 0 to 100 percent. (Values over 100 if the Split Type is ‘per’ are not accepted.) After you have entered all of your split times, if the times are all seconds or tenths of a second, then the cycle length will be calculated automatically as soon as you exit Edit mode. If you have entered your split times as percentages, you will need to supply the Cycle length, in seconds, yourself.

Signal Plan — This number shows which signal plan is being edited. This screen can be used to edit all four of the available signal plans. To switch to another signal plan, press the number button for the signal plan in question (1, 2, 3, or 4).

Timing Plan Transfer Interval — In each Signal Plan, you can specify one interval as the Timing Plan Transfer interval. When a call is made to change to a different timing plan, the controller waits until the end of this interval before it switches to the new plan.

Signal Plan Transfer Interval — Similarly, in each Signal Plan, you can specify one interval as the Signal Plan Transfer interval. When a call is made to change to a different signal plan, the controller waits until the end of this interval before it switches to the new plan.

Flash Entry Interval — In each Signal Plan, one interval can be specified as the Flash Entry Interval. If the controller is switching to Automatic Flash mode, it will wait until the end of this specified interval before making the switch.

Flash Exit Interval — In each Signal Plan, one interval can be specified as the Flash Exit Interval. If the controller is switching from Automatic Flash mode and will be starting this signal plan, the controller will launch the plan by going directly to the beginning of this specified interval.

M.C.E. — (Manual Control Enabled) This value is either OFF or ON for each interval in the plan. When this value is ON (‘X’) for an interval, it is available for variable operation, including a police button advance of the intersection, force-offs, and offset correction

Using the PreTimed Programming Screens

ATC-1000 Advanced Traffic Controller 239

timing. By selecting which of the intervals is enabled in this way, you can control how a police button stepping through the cycle will function. Only those intervals with the X next to MCE will respond to the button.

Actuated — An ‘X’ placed in an interval’s column indicates that the interval is actuated by a detector input. However, the assignment of which detector or detectors (including pedestrian detectors) will cause this actuation is not available from the controller front panel in build 304 of the firmware. To make the detector assignment for each interval, you will need to edit the device database using IQ Link or IQ Central.

Recall — When checked, it indicates that an interval MUST be serviced during the cycle. In effect, this is an artificial call on that interval ; one that isn’t being generated by a detector input.

Non-Lock — By default, intervals are locking on detector inputs, meaning that if a call is placed (and the interval is ‘Actuated’), then the demand for service on that interval remains, even if the call goes away. If you set Non-Lock to ON (‘X’), then this interval’s detectors do not latch in this manner, meaning that if the call goes away, then the demand for service on this interval also goes away.

Note Pedestrian detector calls are always locking, no matter how the Non-Lock parameter is set.

Dwell — An interval marked as Dwell is used by the traffic engine to get the intersection back into coordination. Since pretimed operation does not have other methods for coordination offset recovery, Dwell is the only option available for the coordinator to modify the cycle time in order to resynchronize the intersection with the coordination timing. Typically, only one interval is marked as the Dwell interval, and it’s usually the interval that supplies the Green light to the main traffic artery. However, the ATC firmware will allow multiple intervals to be available for Dwell operation. If more than one are checked (‘X’), and the coordinator needs to Dwell to resync coordination, then it will use the first interval encountered that has the Dwell function flagged.

min — These are the minimum times required for each interval. Valid values can be anything from 0.0 to 25.5 seconds. This is typically used to protect a minimum time for the amber (yellow) portion of a cycle to prevent it from falling below the legal limit for that signal (This is 3.0 seconds in the United States, but the operator can set this minimum to any value in the range mentioned previously.) As of build 304 of the controller firmware, the only function that may potentially shorten an interval, and which must be protected against using this min value, is Transit Signal Priority (TSP) operation. TSP can shorten some intervals in order to recover after a transit vehicle has taken priority in the intersection and knocked the intersection out of coordination.

Pretimed Preemption Screens This screen will host the main parameters to program the six available pre-timed preemption runs.

(MAIN MENU > 2.PROGRAMMING > 7.PRETIMED > 3.PREEMPTION)

2.7.3 PRETIMED PREEMPT

Figure 232 – Pretimed Preemption screen

In build 304 of the ATC firmware, the Pretimed preemption functions are included in the firmware, however the data entry for those parameters are not yet available from the front panel interface. Or, in other words, the capability is there, but it cannot be programmed from the keypad. To program pretimed preemption, you will need to use either IQ Link or IQ Central instead.

Preempt Number — There are six available preemption inputs, each of which can have it’s own values for the following parameters.

Preempt Control (Non-Locking Memory) — When set, the preemption will not occur if the preemption input goes away before the controller has the time to transition to the preemption run. (By default, pretimed preemption inputs are latching.)

Preempt Control (Preempt Override Flash) — When this option is set to ON, the preemption run will not be serviced if the controller is currently in Automatic Flash mode.

Preempt Control (Cycle Dwell) — The pretimed preemption run has a section of intervals called ‘Dwell’. If the Cycle Dwell value is set to ON, then those intervals will be cycled over and over until the preemption call goes away. If this value is OFF, the dwell portion of the run will be served once and then wait in the last dwell interval until the preemption call goes away.

Delay — This is the delay on the start of the preemption run. This is the amount of time (from 0 to 600 seconds) that the controller will wait to service a preemption run after a preemption input becomes active. A Non-Locking run (see Non-Locking Memory, above) whose preemption input goes off before this delay period has completed will not be serviced.

Using the PreTimed Programming Screens

ATC-1000 Advanced Traffic Controller 245

Minimum Duration – This is the minimum amount of time that the entire preemption run must be active, from 0 to 65,535 seconds (0 to 18.2 hours), once it starts being serviced. This timer begins counting at the end of the run’s Delay period. This counter will hold the prun in the Dwell state until this minimum duration time has elapsed.

Maximum Presence — This is the maximum time that an active preemption input can be considered valid. The primary purpose of this function is to prevent a faulty input from locking the preemption run for an excessive amount of time. This can be any value between 0 and 65,535 seconds (0 to 18.2 hours). When set to zero, the maximum presence test is disabled. After an input has been ON for the defined length of time, the input is considered invalid, and the controller returns to normal operation. The preemption input will be considered invalid until it returns to the OFF state.

Per-Interval Parameters

The rest of the pre-timed preemption values are set for each interval in the run.

Time — The duration of each interval of the preemption run. Any interval can be any value between 0 and 25.5 seconds.

Channels 1 through 12 — These are the assigned signals to show, set by the load switch channels for your cabinet. Each channel can be set to one of these values for that interval: None (OFF), Green, Yello, Red, Walk, Flashing Don’t Walk, and Solid Don’t Walk).

Track Clear intervals — These six intervals at the beginning of the preemption run are used for railroad track clearance timing. They are optional and are only used for handling train crossings, specifically to clear the road before a train comes through. If the time value of an interval is zero, then it is unused. Unused intervals must be placed at the end of the Track Clear section. If the time for all these Track Clear intervals are zero, then there will be no track clearance used during the run, and the preemption will proceed directly to the Dwell section of the run (which is the normal setup for emergency vehicle preemption).

Dwell intervals — These six intervals constitute the main body of the preemption run. If the timing for an interval is set to zero, it is considered to be unused. Any unused intervals during the Dwell portion of the run should be placed at the end of the Dwell section. If ALL of the Dwell intervals have a zero time, then the controller will automatically dwell in all red during the run. The used Dwell intervals will be repeated for as long as the preemption input is active if the Preempt Control: Cycle Dwell parameter is set ON.

Exit intervals — These six intervals are used to transition the intersection back to normal operation after the preemption input has gone inactive. Again, intervals with zero time are unused, and any unused Exit intervals should be placed at the end of the run.

Chapter 7 — Pretimed Operation

246 ATC-1000 Advanced Traffic Controller

Additional Notes About Pre-timed Preemption

Pre-Timed Preemption A preemption interrupts the normal sequence of vehicle and pedestrian movements to allow an emergency vehicle or train to have priority through the intersection. The controller creates an orderly green-amber-red sequence of new intervals to reach the preprogrammed preempt plan. If a signal is green and this matches the programmed preempt plan, that signal will stay green while all other signals transition to the preempt plan.

After preempt has ended, the controller will use its programmed timing and signal plans to operate the intersection. If preempt occurs, the controller advances to main street green (interval 1) when the time-based plan would normally have caused this; for example, at a specific time of the internal clock of the controller.

The specifications dictate a priority level for all inputs: preempt input is a higher priority than stop time and cab flash. The result of this is that the controller does not stop preempt processing if the cabinet goes into flash. If an event in the preempt plan causes a flash condition, the controller will not stop three-color operation. The controller and the cabinet must be observed during the preempt operation to determine the cause of any conflict. The controller will honor the stop time input after preempt processing has been completed.

There are several stages to preempt processing:

• Preparation intervals before going into preempt - these are the intervals that cycle the intersection from the current signal conditions (red/amber/green) to the first interval in the track clearance definition (if present) or the first interval in the dwell definition.

The controller uses default times for these new intervals (three seconds for amber, two seconds for red, and three seconds for flashing Don’t Walk). These times can be changed on the Preempt & Interval Skipping tab after the Preempt tab of the pre-timed window. This tab has entries for pedestrian clearance, amber clearance, and red time for each channel.

• Preempt Track Clearance intervals - these intervals are optional and are only used for handling train crossings. If they are not configured, then the first interval run during the actual preempt will be the first dwell interval that follows. If a road crosses a railroad track, a track clearance interval would need to be defined so that the road can be cleared before the train comes through.

• Preempt Dwell stage intervals - these are the actual intervals that run during preempt. These intervals give priority to emergency vehicles.

Using the PreTimed Programming Screens

ATC-1000 Advanced Traffic Controller 247

After the dwell times are completed, these intervals return the intersection to normal operation. Normal operation starts in Interval 1 so the controller will appear to dwell in the last preempt interval until the proper coordinated time to advance to Interval 1. This advance to Interval 1 is the TBC time as determined by the controller’s clock and the current timing plan. Because of this dwell it may appear that the controller has hung. The controller will return to Interval 1 at the same coordinated time, as if the preemption did not occur.

It is possible to configure preempt to flash the dwell intervals. By using the preempt option to cycle the dwell phases and having two alternate intervals of one half second each, the intersection can be doing a flash sequence while in preemption. In the example IQ Link preemption configuration screen shown below, channels 1 and 5 are flashing red simultaneously with channels 2 and 6, which are flashing yellow. Channels 3, 4, 7, and 8 will flash red, but on the alternate half of the 30 second in a wig-wag fashion.

Figure 233 – Wig-wag signals during pre-timed preemption using Cycle Dwell

Preemption intervals can have of maximum duration of 25.5 seconds, so if an interval time greater than 25.5 seconds is desired, duplicate the interval and use times that add up to the desired total time.

Pretimed Preempt and Interval Skipping Screens This screen will be used to host the Pre-timed preemption and interval skipping conditional parameters. These are extra performance requirements placed on the outputs of pre-timed operation during either preemption or interval skipping operation.

Note An interval during normal operation is available for skipping if it is both A) Actuated and B) NOT Recalled.

Figure 234 – Pretimed Preempt & Interval Skipping screen

In build 304 of the ATC firmware, the Pretimed preemption interval skipping function is included in the firmware, however the data entry for these parameters are not yet available from the front panel interface. Again, the capability is there, but it cannot be programmed from the keypad. To program pretimed preemption interval skipping, you will need to use either IQ Link or IQ Central instead.

Channels 1 through 12 — The parameters on this screen are set PER LOAD SWITCH, so the output channel in your cabinet will have the following restrictions.

Ped Clearance — This is a minimum time placed on the pedestrian clearance portion of a pre-timed plan if either interval skipping or a preemption run become active. This is a value in seconds between 0 and 255 that the flashing Don’t Walk signal must be displayed (if present in the plan). If no value is set, there is no minimum ped clearance time requirement during operation.

Amber Clearance — This is a minimum time placed on the vehicular clearance (Yellow/Amber) portion of a pre-timed plan if either interval skipping or a preemption run become active. This is a value in seconds between 0.0 and 25.5. If no value is set, there is no minimum clearance time requirement during operation. The requirement in the NTCIP standard for this feature is: “Following the termination of the Green interval of each channel the controller shall provide a minimum Amber Clearance interval during initial preemption or interval skipping.”

Using the PreTimed Programming Screens

ATC-1000 Advanced Traffic Controller 249

Red Time — After a vehicular clearance (Yellow or Amber) signal and a Ped Clearance signal, this is the minimum time that the controller must show the red signal when transitioning to interval skipping or a preemption run. Valid values are 0.0 to 25.5 seconds.

Additional Details about Skipping and Preemption Transitions

Pre-timed signal plans are based on a predefined sequence of intervals. These intervals have a specific signal light pattern. A series of intervals that control a specific direction of vehicle movements (green, amber, red) is what drives a channel and the output of that channel feeds a load switch.

If more than one interval is defined as actuated, the controller will be able to skip intervals that do not have an associated call on them. The skipping of intervals is from one actuated interval to another actuated interval. For some signal plan configurations, the specific interval defined as actuated might have to be adjusted to achieve the correct color operation on the signal head. Typically, this means that Interval 3 will need to be set as actuated.

Another point to note is that if the signal plan or timing plan transfer interval is not reached, the signal plan or timing plan is not reloaded. This only becomes a factor if the timing or signal plan has been changed via the IQ Link software or some other NTCIP central system. However, the plans will always be loaded when a plan change occurs due to a time-of-day event.

Just like with preempt processing, the controller will have to create new intervals to achieve an orderly and proper transition between intervals. If new intervals need to be created, the controller will use the same minimums for interval skipping as it uses for preempt processing: three seconds for amber, two seconds for red, and three seconds for flashing Don’t Walks. These values can be set on the Preempt & Interval Skipping tab. This tab has entries for pedestrian clearance, amber clearance and red time for each channel. Note that the controller has a minimum three second delay for any amber interval. The below is an example of interval skipping.

Chapter 7 — Pretimed Operation

250 ATC-1000 Advanced Traffic Controller

Figure 235 – Actuated intervals in the IQ Link Pre-timed table

In the above example, intervals 6 and 10 are actuated. The controller will dwell in Interval 1 until a call is placed on Vehicle 1 or Pedestrian 1 (for interval 6) or Vehicle 2 or Pedestrian 2 (for interval 10). If a call is placed on both 1 (either pedestrian or vehicle) and 2 (either pedestrian or vehicle), the controller will cycle through all 12 intervals. If a call is placed on 1 (either pedestrian or vehicle) and no call on 2 (either pedestrian or vehicle), the controller will go from Interval 1 to 6, 7, 8, and 9, then back to Interval 1. If a call is placed on 2 (either pedestrian or vehicle), the controller will go from Interval 1 to 10, 11, and 12 then back to Interval 1.

Note The controller skips from actuated interval to actuated interval (Interval 1 is an actuated interval by default). If there is a specific signal pattern that has to run after Interval 1 but before the actuated Interval 6 (for example to bring up an arrow), then Interval 3 should be defined as actuated and not Interval 6.

Note All interval-skipping configurations must be tested in a cabinet with a correctly configured conflict monitor. Each actuated interval should be tested and watched closely to verify proper three-color operation.

Details About Pre-timed Preemption

ATC-1000 Advanced Traffic Controller 251

DETAILS ABOUT PRE-TIMED PREEMPTION

The controller includes an internal preemptor that can support up to six unique preempt sequences.

Operation Internal Preemption is a special program that operates within the controller. The preemption program accepts commands from six preempt inputs and provides the timing and signal display programmed to occur in response to each.

Preemption controls are applied using the IQ Link software. Internally applied preempt controls have priority.

The preemption program reads the current signal display at the time of preempt and provides transition timing, and signal display, to a specified preempt setting. Once preempt has been satisfied, the preemption program provides an exit transition timing and signal display to a programmed (one for each of the six preempt inputs) return-to-normal condition.

Chapter 7 — Pretimed Operation

252 ATC-1000 Advanced Traffic Controller

Input Priority The Preemption program allows you to set priorities of the preemption inputs. The priorities are as follows:

Table 23 – Input Priority

Input Priority Description

Preempt 1 Normally has priority over Preempt 2. If Preempt 1 becomes active while the Preemption program is in the Preempt 2 routine, the controller immediately terminates the Preempt 2 routine and enters the Preempt 1 routine. When Preempt 2 has been terminated by Preempt 1, control will not return to Preempt 2 at the end of Preempt 1 except when Preempt 2 demand is still present at the end of Preempt 1. The priority of Preempt 1 over Preempt 2 can be cancelled. If the priority has been canceled and the Preempt 1 becomes active while the preemption program is in the Preempt 2 routine, the Preempt 2 completes normally. After Preempt 2 is complete, the controller enters the Preempt 1 routine only if the Preempt 1 demand is still present. When Preempt 2 becomes active while the preemption program is in the Preempt 1 routine, the Preempt 1 routine complete normally regardless of the priority of Preempt 1 versus Preempt 2. After Preempt 1 is complete, the controller enters the Preempt 2 routine only if the Preempt 2 demand is still present. Whenever both inputs become active at the same time, Preempt 1 occurs first.

Preempt 2 Normally has priority over Preempt 3. The priority of Preempt 2 over Preempt 3 can be cancelled via program entry.

Preempt 3, 4, 5, and 6 Normally has equal status (priority cancelled). A priority of Preempt 3 over Preempt 4, Preempt 4 over Preempt 5, and Preempt 5 over Preempt 6 can be set using the IQ Link software. Operation capability as described above for Preempt 1 and 2 is provided for Preempt 2 and 3, 3 and 4, 4 and 5, and 5 and 6. The default priorities above were established assuming Preempt 1 and Preempt 2 were set as railroad and Preempt 3 to Preempt 6 as emergency vehicle (Authorized Engineering Information).

Automatic Flash All Preempt routines will normally have priority over Automatic Flash. If any Preempt becomes active while the controller is in Automatic Flash, Automatic Flash terminates normally and the controller enters the Preempt routine. The priority of Preempt over Automatic Flash can be cancelled using the IQ Link software. If the priority of Preempt over Automatic Flash has been cancelled, and a Preempt input becomes active while the controller is in Automatic Flash, the controller will remain in Automatic Flash until the demand (both Automatic Flash and Preempt) is terminated

Details About Pre-timed Preemption

ATC-1000 Advanced Traffic Controller 253

Input Priority Description

Start Up Flash Start-Up Flash will always have priority over all Preempt routines. If a Preempt input becomes active or is active during Start-Up Flash, the controller maintains the Start-Up Flash condition for the duration of the both Preempt demand and Start-Up Flash time

External Start External Start always has priority over all Preempt routines. If External Start becomes active during a Preempt routine, the controller reverts to Start-Up Flash rather than the Initialization condition. The controller maintains the Start-Up Flash condition for the duration of the External Start, Preempt demand, and Start-Up Flash time

Memory The controller provides input memory which can set to locking or non-locking. When input memory is set for non-locking, termination of the input prior to implementation of the routine will not initiate preempt operation

SETTING UP AN ACTUATED LEADING OR LAGGING LEFT TURN

Some special attention is required when using pre-timed operations to set up the ATC-1000 for a split main street, a leading left turn movement, and skipping on both the side street and the left turn. The actuated interval for the side street must be placed before the interval where the side street turns green, otherwise both sides of the main street will already have changed to red before the side street is skipped. This is because the actuated intervals are the “skip from” and “skip to” points.

Wrong Way to Program a Leading Left Turn Take this example of a pre-timed signal plan 1:

Figure 236 – Wrong way to program a leading left turn in pre-timed mode (IQ Link)

This is the intuitive way to set the side street actuated interval; however when the side street (intervals 6-9) are skipped the start point has both sides of the main street already red. This has channel 2 clear unnecessarily.

Setting up an Actuated Leading or Lagging Left Turn

ATC-1000 Advanced Traffic Controller 255

The pattern with no skipping is as follows:

INT SPL ACC MIN CH1 2 3 4 5 6 1 5.0 5.0 1.0 G G R W D 2 6.0 11.0 1.0 G G R W D 3 10.0 21.0 1.0 G G R F D 4 3.0 24.0 3.0 Y Y R D D 5 2.0 26.0 1.0 R R R D D 6 6.0 32.0 1.0 R R G D W 7 12.0 44.0 1.0 R R G D F 8 3.0 47.0 3.0 R R Y D D 9 2.0 49.0 1.0 R R R D D 10 6.0 55.0 1.0 R G G R D D 11 3.0 58.0 1.0 R G Y R D D 12 2.0 60.0 1.0 R G R D D

When the leading left is skipped to serve the cross street, the skipping sequencer generates this pattern:

INT ORG SPL ACC MIN CH1 2 3 4 5 6 1 1 5.0 5.0 1.0 G G R W D 2 2 17.0 22.0 1.0 G G R W D 3 3 10.0 32.0 1.0 G G R F D 4 4 3.0 35.0 3.0 Y Y R D D 5 5 2.0 37.0 1.0 R R R D D 6 6 6.0 43.0 1.0 R R G D W 7 7 12.0 55.0 1.0 R R G D F 8 8 3.0 58.0 3.0 R R Y D D 9 9 2.0 60.0 1.0 R R R D D

And when the side street is skipped to serve the left turn, this is the generated pattern:

INT ORG SPL ACC MIN CH1 2 3 4 5 6 1 1 5.0 5.0 1.0 G G R W D 2 2 29.0 34.0 1.0 G G R W D 3 3 10.0 44.0 1.0 G G R F D 4 4 3.0 47.0 3.0 Y Y R D D 5 5 2.0 49.0 1.0 R R R D D 6 10 6.0 55.0 1.0 R G G R D D 7 11 3.0 58.0 1.0 R G Y R D D 8 12 2.0 60.0 1.0 R G R D D

The ATC skips from interval 5 to interval 10. Note that because the skipping starts with interval 6, channel 2 has been cleared but it then reverts to green.

Chapter 7 — Pretimed Operation

256 ATC-1000 Advanced Traffic Controller

Correct Way to Program a Leading Left Turn The revised signal plan 1 has the actuated interval for the side street moved to interval 3:

Figure 237 – Correct Programming for a Leading left turn in IQ Link

Red cells have been modified from the previous example.

The pattern with no skipping will be the same as before:

INT SPL ACC MIN CH1 2 3 4 5 6 1 5.0 5.0 1.0 G G R W D 2 6.0 11.0 1.0 G G R W D 3 10.0 21.0 1.0 G G R F D 4 3.0 24.0 3.0 Y Y R D D 5 2.0 26.0 1.0 R R R D D 6 6.0 32.0 1.0 R R G D W 7 12.0 44.0 1.0 R R G D F 8 3.0 47.0 3.0 R R Y D D 9 2.0 49.0 1.0 R R R D D 10 6.0 55.0 1.0 R G G R D D 11 3.0 58.0 1.0 R G Y R D D 12 2.0 60.0 1.0 R G R D D

And the pattern when skipping the leading left turn to serve the cross street is the same as before:

Setting up an Actuated Leading or Lagging Left Turn

ATC-1000 Advanced Traffic Controller 257

INT ORG SPL ACC MIN CH1 2 3 4 5 6 1 1 5.0 5.0 1.0 G G R W D 2 2 17.0 22.0 1.0 G G R W D 3 3 10.0 32.0 1.0 G G R F D 4 4 3.0 35.0 3.0 Y Y R D D 5 5 2.0 37.0 1.0 R R R D D 6 6 6.0 43.0 1.0 R R G D W 7 7 12.0 55.0 1.0 R R G D F 8 8 3.0 58.0 3.0 R R Y D D 9 9 2.0 60.0 1.0 R R R D D

But when the side street is skipped to serve the leading left turn, channel 2 now remains green:

INT ORG SPL ACC MIN CH1 2 3 4 5 6 1 1 5.0 5.0 1.0 G G R W D 2 2 36.0 41.0 1.0 G G R W D 3 0 3.0 44.0 3.0 G G R F D 4 0 3.0 47.0 3.0 Y G R D D 5 0 2.0 49.0 2.0 R G R D D 6 10 6.0 55.0 1.0 R G G R D D 7 11 3.0 58.0 1.0 R G Y R D D 8 12 2.0 60.0 1.0 R G R D D

The ATC skips from interval 2 to interval 10, generating new clearance intervals for channel 1 with channel 2 remaining green.

Note that in the modifications the “do not lock here” intervals for actuated interval 3 extend from interval 3 to interval 7. This means that detector calls for interval 3 will not lock during these intervals. This is not a problem since intervals 3-5 only ever occur when the side street is not skipped, so there is already a locked call, and if any additional calls were locked they would just be cleared in interval 6 anyway. Whenever the ATC is dwelling at main street green, or while the side street is being skipped, any calls will be locked.

Chapter 7 — Pretimed Operation

258 ATC-1000 Advanced Traffic Controller

Correct Way to Program a Lagging Left Turn The following example shows the correct way to implement a lagging left turn. This configuration of signal plan 2 uses the same vehicle detector inputs and pedestrian call inputs as the previous example of signal plan 1; vehicle detector one and pedestrian call input one bring service to the cross street whereas vehicle detector two serves the left turn.

Note that the order of vehicle detectors is independent of intervals or interval sequence. Actuated interval seven is not assigned any vehicle detector but is used to indicate the desire to skip the termination of channel 2 (the concurrent main street green) when the left turn terminates in order to return to both directions of main street traffic vehicle movements. Because the intervals for the left turn and cross street are at different locations in the sequence of intervals for signal plans 1 and 2 then different timing plans must be used that have matching timings for the two different signal sequences. However, if the correct timing plans are invoked for each signal plan then it is possible for a change from a leading left turn to a lagging left turn based on time of day operation using these two signal plans.

Figure 238 – Programming a lagging left turn

Setting up an Actuated Leading or Lagging Left Turn

ATC-1000 Advanced Traffic Controller 259

It should be noted that preempt and interval skipping table should be programmed with the desired minimums for Ped Clearance, Amber Clearance and Red Clearance times for the corresponding channels, as shown in Figure 239.

These values will be used during the skipping operation of the controller for any intervals that may be generated on the fly when the controller goes to service the calling detector. Intervals in the signal plan will be skipped but coordination will be fooled into thinking the interval progression is normal. Furthermore, the controller will have to create intervals in order to terminate pedestrian and vehicle movements safely by inserting new pedestrian clearance indications, yellow change and red clearance indications.

OVERVIEW

The ATC-1000 controller has screens to configure up to six preemption patterns. These patterns are configured on these six screens, which can be navigated using the UP+ and DWN– buttons. The exact preemption inputs and outputs used by the controller depend on which of the I/O modules are being used in your unit. (See “Chapter 13 — I/O Module Connector Details” starting on page 329 for details on pin assignments.)

Note The topics in this chapter describe Phase-based preemption. Pre-timed preemption is handled in a separate set of screens and with a different operating theory, which are described in the “Error! Reference source not found.” topic, starting on page Error! Bookmark not defined..

Overview

ATC-1000 Advanced Traffic Controller 263

Before we get into the meanings of each of the parameters on the Preemption screens, we must first introduce the basic operating theory of preemption in the Peek ATC controllers. The ATC-1000 has six available preemption runs, each associated with a Preemption Call input. So preemption input 1 calls Preemption Run #1, and so on. Each of the Preemption Runs can have up to four ‘phases’, but not all of these phases need to be used in each run. Figure 242 shows the basic ‘phases’ of a preemption run. (Note that these preemption ‘phases’ are not the same thing as a NEMA phase, but merely parts of the ATC run.)

Figure 242 – Phases in a Peek ATC Preemption Run

A preemption run goes through the four phases in sequence, and it does not repeat the sequence. Preemption is a ‘once through’ set of steps.

The ‘Track’ phase is optional. Most of the time used by a preemption run is typically taken up by the Dwell phase, which is normally the phase in which the green signal is shown along the street on which an emergency vehicle, or other prioritized traffic, will travel. The values for all portions of a Preemption run are defined on a single screen in the controller.

Chapter 8 — Preemption

264 ATC-1000 Advanced Traffic Controller

Preemption Linking One additional feature of ATC preemption is the ability to link one preemption run to another. This Link can be defined in each of the runs, but only to a higher number run (so run 5 can link to 4 or 3 or 2 or 1, but run 1 cannot be linked to any other run.) A run with a defined link switches to that run after it completes its own Dwell phase. And it links to the new run at the beginning of its Track phase. The new run is maintained as long as the initial preemption call input is active. When the call goes away, the new run exits as it normally would. This is shown in Figure 243 on page 264.

It is possible to link multiple preemption runs in this way. One could link all six preemption runs in this way, creating a single preemption call that generates one entry, six different track and dwell phases, and one exit phase.

Figure 243 – Preemption run linking

Overview

ATC-1000 Advanced Traffic Controller 265

Preemption Parameters Here are the details about the various preemption parameters:

Non-Lock Call — This toggles on (‘X’) or off (‘ ‘) to indicate whether this preemption run has a non-locking input call. This means that if Non-Lock Call has an ‘X’, and if a call is placed on this Preemption input, but the call goes away before the Delay timer has completed (see ‘Delay’, below), the call will be discarded and no preemption run will result.

Flash Dwell — This is an option that tells the preemption run how to handle phases that are marked as a ‘DWELL Ph’. When this option is checked ‘X’, dwell phases in the run flash Yellow during the dwell period. Active phases that are not listed as dwell phases will flash Red. If you inadvertently mark conflicting phases as dwell phases, all active phases will flash Red.

Override FL — Do not allow preemption to override flash. If this option is checked ‘X’, a preemption call will not override automatic flash mode.

PRTY Override — Normally, preemption calls are able to interrupt one another with no priority, the Priority Override command, however, tells this preemption run that the priority order of the preemption numbers will apply to this run. If this option is checked, the number order of the call is important, Preemption run 1 is a higher priority than 2 and so on. So, if the controller is running Preemption Run #3, and a Preemption #2 call comes in, and the PRTY Override for run #3 is set to ‘X’, then Preemption #2 will interrupt Run 3 and begin operating. If PRTY Override was set to ‘ ‘, Run #3 would continue and the controller would ignore the Preemption #2 call.

Track Ph — Use these check boxes to select which phases will be green during the ‘Track’ clearance phase portion of the run. This portion of the run is optional. You do not need to have any phases selected and it can still be a valid preemption run.

Dwell Ph — Use the Yes and No buttons to select which of the intersection phases will be Green during the Dwell portion of the preemption run. An ‘X’ indicates that this phase will be a Dwell phase during the run. At least one Dwell phase is required in order for the controller to judge this is a valid preemption run. If the Flash Dwell option is checked, above, then these phases will be displayed as flashing yellow rather than green.

Dwell Pd — Use this array to select which of the intersection phases will be pedestrian Walk phases during the Dwell portion of the preemption run.

Exit Ph — Use this array of checkboxes to select which of the intersection phases will be green during the Exit portion of the preemption run.

Delay — This is a delay time, in seconds, that the controller will wait after the preemption input goes active before the controller will begin executing the Entry phase of the run. Note that if the input goes OFF before the delay time is over, and the Non-Lock Call option is selected above, the run will not start.

Chapter 8 — Preemption

266 ATC-1000 Advanced Traffic Controller

Min Green — This is the minimum amount of time, in seconds, that any of the preemption phases can be allowed to show a green signal. This is to prevent a Dwell or other phase from being truncated in an unsafe manner should the preemption input suddenly go away. This minimum time also applies to the normal operation greens that are active when the Preemption run is first activated.

Min Walk — This is similar to the Min Green function for preemption, only it prevents any Pedestrian Walk phase during the preemption run from being cut off by the sudden removal of the preemption input signal. This is the minimum time, in seconds, that should be allowed for preemption run Walk signals. This minimum walk time also applies to the normal operation pedestrians phases that are being serviced when the Preemption run is first activated.

Ent Ped Clear — This is the amount of clearance time that is allotted to a pedestrian phase that is interrupted by the preemption run. The actual amount of time that is used for pedestrian clearance is either this time, or the time stored in the normal pedestrian phase, whichever is the lower value.

Track Green — The amount of time, in seconds, that is allotted to the Track phases portion of this pedestrian run. The default value is zero.

Dwell Green — The amount of time, in seconds, that is allotted to the Dwell phases portion of this pedestrian run. This is the minimum time that can be used by the dwell phases. The actual duration of the Dwell phase will be a combination of the preemption input signal, this Dwell Green minimum value, and the Max Duration time shown below.

Max Duration — This is the minimum length of time, in seconds, that the full preemption is allowed to run. This timer begins at the end of any Delay time you’ve placed on the run input, and it will prevent the Dwell phase from ending until this time has elapsed.

Max Presence — This is the time in seconds that the controller will consider a preemption input valid. If the preemption detector is faulty, or if a vehicle parks within sight-line of the preemption receiver and keeps the intersection input high the whole time, this timer functions as a ‘time out’ for the preemption input.

Link — This is a way to link the operation of one preemption run to another, but it only works if you are linking to a higher priority run (i.e. Run #2 links to Run#1 is valid, but Run#1 cannot link to any other run) The link is activated at the end of the Dwell phase of the current run, and jumps to the beginning of the Track phase of the linked run. The rest of the new run is performed as defined, however it’s input is controlled by the original run’s preemption call input.

Chapter 9 — Transit Signal Priority

268 ATC-1000 Advanced Traffic Controller

WHAT IS TSP?

TSP stands for ‘Transit Signal Priority’. In a way, TSP is similar to preemption, but instead of being triggered by emergency vehicles like ambulances, police cars and fire rescue vehicles, it is triggered by public transportation vehicles, usually buses. And rather than triggering a hard ‘preemption’ of the normal intersection pattern, a TSP call provides a more subtle adjustment of traffic flow. It creates a ‘priority’ change in the intersection operation, meaning the transit vehicle is given preference by the traffic controller over timing and signal changes.

Figure 244 – TSP Timing Adjustment in an Intersection

For example, if the light is green in the direction the transit vehicle is currently travelling, the controller will hold the green long enough for the bus to get through the light. If the light is red in the direction of travel, the controller will shorten the cross street’s greens to bring up the green light for the transit vehicle more quickly. These are the basics of how TSP functions; however, there are complexities to how this is implemented and how it functions on real city streets. These are discussed in greater detail in the rest of this chapter.

How TSP Functions in the Peek ATC Controller

ATC-1000 Advanced Traffic Controller 269

HOW TSP FUNCTIONS IN THE PEEK ATC CONTROLLER

Although TSP has been defined in general terms by the U.S. Department of Transportation, there is not truly ‘standard’ way that it is implemented. Each city and equipment manufacturer has been required to decide how to implement the capability. In the Peek ATC controllers, TSP has been implemented using the parameters stored in the TSP menu, shown in Figure 245.

2.8 TRANSIT PRIORITY MENU 1. UNIT PARAMETERS 2. RUN PARAMETERS 3. ACTIONS PLANS 4. RUN CONFIGURATION 5. QUEUE JUMPING 6. SPLIT TABLE

Figure 245 – Transit Priority Menu

It is important to take a moment to understand the way that Transit Signal Priority is applied to intersection operation in the Peek ATC controllers, as it can be a bit confusing to those unfamiliar with the process. As shown in Figure 246, the operator can select one of 48 ‘TSP Action Plans’ which are composed of a Run Config number and a couple other parameters. This Run Config calls one of eight TSP Run Configurations. Each Run Configuration includes 8 individual TSP ‘Runs’ that can be called at any time when that Run Configuration is active. A TSP Run is somewhat equivalent to a Preemption Run, meaning it is a sequence of events that occur when a TSP call is detected. There are eight Runs in each Run Configuration, so that a separate set of events can be triggered for each phase in a standard 8 phase intersection. This also corresponds to the eight TSP inputs available on the ATC controllers.

Although there are only 8 sets of Runs that can be chosen by your TSP Action Plans, each Action Plan can also enable/disable individual runs, and also change the re-service time and recover strategy to be used by all of the runs in the current active plan. This provides some additional options beyond the eight basic Run Configurations.

Chapter 9 — Transit Signal Priority

270 ATC-1000 Advanced Traffic Controller

Figure 246 – TSP Action Plans, Run Configs and Runs

So, as you can see from the above illustration, there are 48 available TSP Action plans in the ATC controller. Each Action plan can call one and only one of the eight available Run Configurations, however each Action plan can enable or disable individual runs within the selected Run Configuration. Which TSP Action Plan the controller uses at any given time is normally defined by the TOD schedule, however there are also default action plans that can be defined for whenever the controller is under central system control. TSP operation is not supported when the controller is running in Free mode.

Each Run Configuration is a set of 8 individual runs that are all available at the same time in the intersection. The fact that multiple ‘runs’ are available allows you to set up a

How TSP Functions in the Peek ATC Controller

ATC-1000 Advanced Traffic Controller 271

different signal behavior based on which TSP input is detected, meaning if you detect a bus coming southbound, you might call Run 1, but if you detect a bus coming eastbound, you can call Run 2 instead.

Each run is a set of time changes and methods that grant the transit vehicle a higher priority to green lights within the intersection. The time changes are set in the TSP Split table (option 6 on the Transit Priority menu). The methods to be used are specified by the user in each Run Configuration.

Chapter 9 — Transit Signal Priority

272 ATC-1000 Advanced Traffic Controller

Prioritization Methods The Peek ATC controllers actually provide the higher priority for the transit vehicle in a number of ways. Four are described in the US DOT TSP Handbook, and Peek supplies an additional method not described there. Any or all of these methods may be used in conjunction with one another:

Green Extension — This is the primary method used by most TSP systems. Green extension simply extends the amount of time available to the transit vehicle’s green light. The ATC controllers provide a number of options on how to deal with the associated pedestrian phases or intervals.

Early Green — The most common secondary method used in most TSP systems is to shorten the green times on the other phases in the intersection. So if the North/Southbound lanes are currently being serviced in green, and a bus approaches in the Eastbound direction, the Early Green method would reduce the amount of time the green is displayed to North and Southbound traffic; bringing the green to the bus more quickly. This method is known as ‘Reduction’ in the ATC interface.

Phase Insertion — This method is used when there is a dedicated signalized transit lane or turn lane that is only activated when a transit vehicle is present. This is possible in the ATC interface by setting up dedicated phases for transit vehicles with zero split times. The phase can then be activated via the normal Green Extension function, which takes the phase to a non-zero split time, which then gets serviced. This method of phase insertion is sometimes known as “Phase-On-Demand”.

Phase Rotation — This method can be used if more than one phase must be served before the transit phase can be served. If phase rotation is configured, the two upcoming phases are ‘rotated’, thus serving the transit phase first, and then going back to serve the other rotated phase, before going back to the normal order. In the ATC environment, this is labeled as a phase ‘Shift’.

Phase Skipping — This option is not described in the US DOT TSP handbook but is provided in the ATC environment. This is a simpler version of rotation, in that the intervening phase is simply skipped during the current cycle so that the transit phase can be serviced more quickly. This is often used to skip a dedicated turn signal, since any vehicles that might be stranded in that phase can usually proceed during the subsequent through-phase.

The ATC environment provides options to serve TSP during independent local NEMA operation (most of the methods assume that this is the baseline operating mode), but also during coordinated NEMA operation, pre-timed operation, and Free operation.

Individual Run Configurations can be set up with their own input signal extend, delay, and failure detection options. And a modification of the basic operation is available to allow a bus to jump ahead of the normal traffic queue. This is known as ‘Q Jumping’.

Getting TSP Set Up

ATC-1000 Advanced Traffic Controller 273

GETTING TSP SET UP

These are the basic steps to get started with Transit Signal Priority Operation.

1. Choose and install a vehicle detection system on your transit vehicles and at the intersections to be given TSP response.

2. Determine which approach detection output will be fed into which input on the Controller. The particular input/output module installed in your ATC-1000 will determine which pins or input method should be used to connect the detection signals to the controller. (See “Chapter 13 — I/O Module Connector Details”, starting on page 329 for pin assignment information.) The ATC-1000 can accept up to 6 inputs for TSP signals.

3. Go into the Run Parameters screen and enter the type of TSP Inputs you wish to use. (MAIN MENU > 2.PROGRAMMING > 8.TRANSIT SIGNAL PRIORITY > 2.RUN PARAMETERS)

4. We’re going to start out by setting up one TSP Action Plan (Number 1) and one Run Configuration (also Number 1). Go into the Action Plans screens (MAIN MENU > 2.PROGRAMMING > 8.TRANSIT SIGNAL PRIORITY > 3.ACTION PLANS), and on screen 1 (the first one that appears), enable all of the TSP inputs that you will be using.

5. Now go into the Run Configuration screen (MAIN MENU > 2.PROGRAMMING > 8.TRANSIT SIGNAL PRIORITY > 4.RUN CONFIGURATION) and on the first Run screen (“Run #1 of 8”) put ‘X’s under each Call to indicate which phases will be extended based on TSP Input 1. Enter which phases will be active Queue Jumps based on TSP Input 1. (Be sure the Queue Jump phases are also checked in the Calls array.) And finally, put X’s next to each phase that will be skipped, shifted, or reduced as a result of this TSP Input 1.

6. Press the DWN – button to go to the screen for Run 2 in Run Configuration 1. Repeat the actions of Step 5 for the phases that will be affected by TSP Input 2.

7. Repeat the above two steps for each of the 8 Runs in Run Configuration 1.

8. Go into the TSP Split Tables screens (MAIN MENU > 2.PROGRAMMING > 8.TRANSIT SIGNAL PRIORITY > 6.SPLIT TABLE) and enter values for GRN EXT for each phase on each of the 16 split tables screens. (You will need to know how your normal split tables are timed in order to do this wisely.) Note here that we are assuming that you are using the normal Green Extend, which also extends your Solid Don’t Walk pedestrian phases. If you wish to use a different Green Extend mode, that value would be set in step 3 above, on the Run Parameters screen.)

Chapter 9 — Transit Signal Priority

274 ATC-1000 Advanced Traffic Controller

9. Go to the Time of Day Actions screens (MAIN MENU > 4.TIME OF DAY > 1.ACTIONS) and place a value of ‘1’ under each TOD event that gets used in your system. (This is calling TSP Action Plan 1 for all of your TOD values.)

10. Go onto the Unit Parameters screen in the TSP menu (MAIN MENU > 2.PROGRAMMING > 8.TRANSIT SIGNAL PRIORITY > 1.UNIT PARAMETERS) and put a ‘1’ next to Default Coord Pattern, Systems TSP Action Plan, and Default TSP Action Plan.

11. Finally, on the same screen (Unit Parameters), change the value of TSP Enable from OFF to ON (using the YES button). This will enable TSP actions in the intersection whenever TSP calls are detected and passed to the controller.

Important There are numerous places in the chain of requirements

where you may run into problems setting up TSP operation on the ATC controller. To help with these, we’ve added a TSP Troubleshooting section to “Chapter 10 — Configuration and Maintenance”, starting on page 313.

Note The above procedure assumes a very simplified TSP configuration with only a single Action Plan and Run Configuration, and the default methods used for Green extend and other variables. You can, of course, modify these steps to make your TSP plan as simple or complex as are needed within each intersection, including placing delays and extends on individual TSP inputs, setting up multiple run configurations called by multiple TSP action plans that can then be called by events in your TOD schedule, or by other triggering events such as Central pattern changes. The rest of this chapter describes the details of those features, should you wish to utilize them.

Unit Parameters The Unit Parameters screen under the Transit Priority menu is used to set and store values related to global TSP operation. (MAIN MENU > 2.PROGRAMMING > 8.TRANSIT SIGNAL PRIORITY > 1.UNIT PARAMETERS)

2.8.1 TRANSIT UNIT PARAMETERS PG 1 OF 1 TSP ENABLE: OFF DEFAULT COORD PATTERN: 000 (0-253) SYSTEM TSP ACTION PLAN: 00 (0-48) DEFAULT TSP ACTION PLAN: 00 (0-48) UTILIZATION PERIOD: 00 (0-24)

Figure 248 – Unit Parameters screen

TSP Enable — This is the ‘master switch’ to turn the TSP capability ON and OFF in the ATC controller. TSP ENABLE is OFF by default, but it must be ON for TSP to be used in the intersection.

Default Coord Pattern — This is the TSP Action plan to use when the controller goes into NEMA Free operation (Pattern 254) and a transit vehicle is detected. A value of 0 (zero) means that the ATC controller should not use TSP during NEMA Free operation. The default value is 0.

System TSP Action Plan — If the controller is under central system control (i.e. there currently exists a Central Override, Traffic Responsive, or Adaptive pattern call from a central system), then this is the TSP Action plan to run whenever a transit vehicle is detected and the current pattern is in the range from 1 to 48. You can call any of the 48 TSP action plans, or set it to 0 (zero) to disable TSP operation whenever the controller is under System control. If the controller is not under a system command and not currently in Free operation, it will use whatever TSP Action plan is specified in your TOD table. The default value is 0.

Default TSP Action Plan — This is the TSP Action plan to use when the controller goes into NEMA Free operation (Pattern 254) and a transit vehicle is detected. A value of 0 (zero) means that the ATC controller should not use TSP during Pretimed Free operation. The default value is 0.

Utilization Period — This parameter is used for logging the effectiveness of TSP operations in the intersection. This Peek-specific parameter tells the controller how often (in hours) to log data on the operating effectiveness of TSP actions. This is similar to the

TSP Screens and Parameters

ATC-1000 Advanced Traffic Controller 277

Peek MOE (Measure-of-Effectiveness) logging feature of the 3000E controllers. A value of 0 (zero) disables this form of logging. The default value is 0. There is more detail about configuring and managing data logging services in the ATC controller starting on page 301.

Run Parameters This screen provides a location to enter parameters that are global values, per Run. (MAIN MENU > 2.PROGRAMMING > 8.TRANSIT SIGNAL PRIORITY > 2.RUN PARAMETERS)

Figure 249 – Run Parameters screen

Input Mode — Each TSP input channel can be assigned to use one of three input methods to generate a ‘TSP Request’, depending on what type of detection equipment (and the resulting detection output method) is installed at the intersection.

Note A ‘Run Request’ is an internal ATC controller concept that functionally means the Run Input + the Input Mode method for determining the request length.

Mode 0 — Constant Call. Uses Check-In input as a steady signal. This tells the TSP algorithms that the input signal on that channel stays on the entire time that the transit vehicle is in range of the detector. In Mode 0, the detection signal is assumed to stay ‘True’ from the time the detector first detects the vehicle, until the vehicle passes through the intersection or out of sight/range of the detector. This is the most common type of signal generated by devices that use a single output channel per detector. This is the default mode for all Run inputs.

Mode 1 — Check-in Check-out. This input mode uses both the Check-In and Check-Out inputs. This mode assumes that the detector generates a short pulse on one channel when the transit vehicle is first detected, and a second short pulse on the other channel when the detector loses sight of the vehicle.

Chapter 9 — Transit Signal Priority

278 ATC-1000 Advanced Traffic Controller

Mode 2 — Check-in Plus Time. This input mode uses the Check-In input channel, when the detector only sends a short High signal pulse when the transit vehicle is first detected. The ‘TSP Request’ that results from this signal is then active for a preset number of seconds, defined by the Extend time that you define for each Run on the Run Configuration screen.

Green Extend Mode — This value determines how the green extend prioritization method deals with the extra phase time for related pedestrian phases, on a run-by-run basis. In all cases, the FDW (Flashing Don’t Walk) portion of the pedestrian phase is not changed. It remains at the value defined in the current pattern. This mode also determines whether or not the TSP modification will be allowed to occur, based on where the associated pedestrian phase is in its signal processing. Meaning, the way that TSP Green Extend operates also depends on at what point in the pedestrian phase the TSP input signal arrives.

Mode 0 — Don’t Walk mode. For TSP Green Extend to be granted, the TSP input must arrive before the end of the flashing Don’t Walk (FDW) portion of the Pedestrian phase. When TSP Green Extend is allowed to occur, the extra time is also added to the Solid Don’t Walk portion of the pedestrian phase. This is the default mode for all Runs.

Mode 1 — Don’t Walk mode with an End of Walk decision. For TSP Green Extend to be granted, the TSP input must arrive before the end of the Walk portion of the associated Pedestrian phase. When TSP Green Extend is allowed to occur, the extra time is added to the Solid Don’t Walk (SDW) portion of the pedestrian phase.

Mode 2 — Walk mode. For TSP Green Extend to be granted, the TSP input must arrive before the end of the Walk portion of the Pedestrian phase. When TSP Green Extend does occur, the extra time is added to the Walk portion of the pedestrian phase.

Mode 3 — Walk and Don’t Walk mode. For TSP Green Extend to be granted, the TSP input must arrive before the end of the Walk portion of the Pedestrian phase. When TSP Green Extend is allowed to occur, the extra time is split between the Walk and Solid Don’t Walk portion of the pedestrian phase.

Mode 4 — Walk and Don’t Walk mode, plus Advance Cancel. Mode 4 is the same as Mode 3, except that it is aware of the Advance Cancel input. If the Advance Cancel Input transitions from active to inactive, this mode terminates the Walk extension and the pedestrian phase advances to the Flashing Don’t Walk portion of the ped phase.

TSP Action Plans Option 3 under the Transit Priority menu is where TSP Action Plans are defined. Use the UP + and DOWN – keys to switch between the 48 available action plan definition screens. (MAIN MENU > 2.PROGRAMMING > 8.TRANSIT SIGNAL PRIORITY > 3.ACTION PLANS)

2.8.3 TRANSIT ACTION PLAN 1 OF 48 RUN # 1 2 3 4 5 6 7 8 Run Enable: Run Configuration: 001 (1-8) Master Reservice Time: 00000 (0-65535) Recovery Strategy: 0 (0-2) 0 = Normal 1 = Offset Correction 2 = Split Balance

Figure 250 – TSP Action Plan screen

Run Enable settings — In each of the 48 TSP action plans, it is possible to disable one or more of the 8 available runs in the selected Run Configuration (See next item). Place an ‘X’ under the run number (by pressing the YES button) to enable that run. By default, all runs are disabled.

Run Config — This is where one of the eight available Run Configurations is chosen for use in this TSP Action plan. This tells the action plan which set of 8 Runs will be available in the intersection while this Action Plan is in effect. The default value is Run Config = 1.

Master Reservice Time — Reservice time is the amount of time that the controller locks out all additional TSP requests after completion of a TSP Run. A value of 0 (zero) means that this reservice limit is deactivated, meaning a second TSP call will be accepted immediately after the first call. This is the ‘Master’ reservice time. Note that there is also a reservice time value associated with each Run Configuration. Whichever value is greater (either the Master Reservice Time stored here in the selected Action Plan, or the Reservice Time stored in the associated Run Configuration) will be the active requirement in the intersection.

Recovery Strategy — This is a parameter that is only used with the ambient pattern that the TSP action interrupts is a NEMA coordinated pattern. It defines how the controller will respond after the transit vehicle has gone through the intersection to recover from the changed timing, and its effect on coordinated operation. The three possible modes are:

Chapter 9 — Transit Signal Priority

280 ATC-1000 Advanced Traffic Controller

Mode 0 — ‘Normal’ recovery. In this mode of recover, the TSP module restores the offset by extending/reducing phase times over one or more cycles (within the max and min times of the cycle’s phases.) This is the default recovery method.

Mode 1 — ‘Offset Correction’ recovery. In this option, the TSP module terminates its operation as soon as it is finished extending and reducing phases in the current cycle. It then steps aside to allow the Coordinator module to use its own Offset Correction methods to recover the offset time.

Mode 2 — ‘Split Balance’ recovery. This is a variation of the Mode 0 recovery method. Again, the TSP module itself is the one managing the offset recovery. The difference from Mode 0 is that in Mode 2, the times of phases are adjusted by the TSP module in exactly inverse of the TSP operation. So if a phase was green extended, during recovery operation it is reduced by the same number of seconds. And if phases were reduced, they will be extended by the same number of seconds during the recovery effort. For example, if the TSP phase is Phase 4, Mode 2 recovery might look like this (depending on your exact extend and reduce times:)

Table 24 – Split Balance recovery method - example

TSP Screens and Parameters

ATC-1000 Advanced Traffic Controller 283

Config Number — This is the Run Configuration number for this set of Run screens. This can be any value between 1 and 8, and is changed by pressing the 1 through 8 buttons on the ATC keypad at any time. When you do so, you are not changing this value, but instead switching to another set of Run Configuration screens. (See above.)

Run # — This indicates which of the eight runs within the Run Configuration you are currently viewing or editing. You can navigate between the Run screens by using the Up and Down buttons.

Delay — This is a modification on the TSP input that feeds this run. When set, the TSP Run waits this number of seconds before processing the request. An example use could be that a bus has non-directional TSP indicator and crosses the street upstream in one direction of the intersection. You would not want that bus to trigger TSP activity in this intersection, so you could put a delay in to cover the period when the bus may be visible by this intersection’s TSP detector. The default value is 0.

Ext — (Extend) This is also a modification on the TSP input that feeds this run. If Extend is set, the input is artificially maintained ON for this number of seconds beyond the time it would normally turn OFF in each of the three input modes. (For a discussion of ‘Input Mode”, see page 277.) The default value is 0.

Note The Extend value on this screen is NOT the amount of time that the green is extended when the TSP Input is received. The actual extension time values for TSP operation are set on the TSP Split Table screens. (MAIN MENU > 2.PROGRAMMING > 8.TRANSIT SIGNAL PRIORITY > 6.SPLIT TABLE)

Fail — This is a test on the TSP input. If the input stays ON for this number of seconds, the input is ignored, and no further inputs on this channel will be accepted until the ON signal goes away. This has a couple of purposes. It can take care of the case where a transit vehicle may be stopped near an intersection for repair, or for some other activity, and the TSP emitter on the vehicle remains on and visible to the intersection’s TSP detector. Or it can also handle the case where the detector or input line are faulty and keep the input ON in error. The default value is 0.

Reserve — (Reservice) Reservice time is the amount of time that the controller locks out all additional TSP Requests after a TSP Run has finished. (Actually, for reservice criteria, the test is actually the time since the TSP Request went away OR there is a Clearance Fail.) A value of 0 (zero) means that this reservice limit is deactivated, meaning a second TSP call will be accepted immediately after the first request. The value stored on this screen is the ‘Per Run’ reservice time. Note that there is also a reservice time value associated with the overall TSP Action Plan, known as the Master Reservice Time. Whichever value is greater (either the Master Reservice Time described on page 279, or the Reservice Time stored here in the individual Run) will be the active requirement within the intersection.

Chapter 9 — Transit Signal Priority

284 ATC-1000 Advanced Traffic Controller

Calls — This is the master list of phases or intervals that will be serviced by TSP actions whenever this TSP Input is activated and this TSP Run Configuration group is the selected group. When an ‘X’ is placed under one of these calls, the associated phase number, or interval if running in a Pre-timed pattern, will receive the calls to Green Extend. Green Extend is the default action of a TSP priority call. If you wish to apply the additional Q Jump function available below, the phases also need to be selected here in the Calls array. Use the YES button to place an ‘X’ and the NO button to remove an ‘X’.

Q Jumps — This array of values is used to enable and disable Queue jumping on the selected phases or intervals when a TSP input is received on this channel. Typically, this is an extra phase or interval that is only activated during TSP actions. For a Q Jump action to occur, an ‘X’ must be placed in that phase/interval, and the associated Call phase above must also be checked. Use the YES and NO buttons to control which Q Jump phases are checked.

Skip phases — Use the YES and NO buttons to places ‘X’s next to those phases that should be skipped over during the upcoming cycle as a result of this TSP input. If the same phase is called above in the Call array and also here in the Skip array, the Skip action will be ignored. In US DOT vernacular, this is known as the ‘Phase Skipping’ capability. This TSP method will not be used if the controller is currently operating in a Pre-timed pattern.

Shift phases — Use the YES and NO buttons to places ‘X’s next to those phases that will be shifted to the most favorable sequence position within the phase’s concurrency group, causing quicker transit vehicle service.

Example: Standard 8-phase dual ring sequence, TSP phase = 4/8, Shift phase = 4/8. If a TSP call occurs during 2/6, shifting causes 2/6 -> 4/8 -> 3/7 -> 2/6. If a TSP call occurs during 3/7, no shifting occurs because 4/8 are in the most favorable position.

Reduce phases — Use the YES and NO buttons to places ‘X’s next to those phases that should be split reduced. The normal way to use this is to have all of the phases that are not selected as Calls (above) be selected (‘X’) to allow them to be split reduced. In US DOT vernacular, this is known as the ‘Early Green’ capability. This TSP method will not be used if the controller is currently operating in a Pre-timed pattern. The Reduce flag shortens intermediate phase splits, thus causing an earlier TSP phase start than would be possible otherwise.

Reserve phases — This option allows a Shift phase to run twice per cycle.

TSP Screens and Parameters

ATC-1000 Advanced Traffic Controller 285

Queue Jumping ‘Queue jumping’ inserts a “Transit-Vehicle Signal” into the cycle, while holding the associated phase Red, thus allowing the transit vehicle to jump out ahead of the rest of the queue waiting at the lights. The way that queue jumping operates is defined on the Queue Jumping screens under the Transit Priority menu. Each screen corresponds to one of the six Queue Jump outputs on the controller. (MAIN MENU > 2.PROGRAMMING > 8.TRANSIT SIGNAL PRIORITY > 5.QUEUE JUMPING)

2.8.5 QUEUE JUMPING OUTPUT 1 OF 6 Queue Jump Time: 000 Enabled Phases: 1 1 1 1 1 1 1 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 Enabled Intervals: 1 1 1 1 1 1 1 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 cont. 1 1 1 2 2 2 2 2 2 2 2 2 2 3 3 3 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2

Figure 255 – TSP Queue Jumping screen

When a phase is marked as a QJump phase in the Run Configuration screens, the controller searches the Queue Jumping Output screens to see which screen has an ‘X’ next to that phase as well. If you say that phase 2 is a QJump phase on the Run screens, the controller will then look through the six Queue Jumping output screens to find one that has phase 2 selected. When the phase is found, the output pin corresponding to that screen (Output 1, in our example above) is sent High for the number of seconds specified on that screen. (or ‘8’ seconds in our example.) This search only looks for the first instance of that phase on the six Queue Jumping Output screens, and then discontinues so that the TSP Run can continue.

Queue Jump Time — This is the time, in seconds, that this Transit Vehicle Signal output (aka ‘Queue Jumping Output’) goes High.

Enabled phases — This array indicates which phases in the cycle, if indicated with a QJump ‘X’ in the TSP Run screens, will trigger this Queue Jump output.

Enabled intervals — These fields are not currently implemented since TSP does not function during Pre-timed operation.

Split Table These tables are the times, in seconds, that are added on a phase-by-phase basis, when TSP is activated on the given phase. These times are the maximum allowable extension and reduction times that are used on the associated split table. If the current pattern is running split table 10, then the TSP Run uses TSP Split Table 10. (MAIN MENU > 2.PROGRAMMING > 8.TRANSIT SIGNAL PRIORITY > 6.SPLIT TABLE)

Figure 256 – Split Table screen The sixteen screen correspond to the 16 screens in the coordination split tables. (MAIN MENU > 1.PROGRAMMING > 3. COORDINATION > 3. SPLIT TABLE) You can define how times will be added to and reduced from the 16 available phases (in NEMA Phase-based pattern operation) when TSP operations causes that phase to be Green Extended. All times are in seconds. GRN EXT — (Green Extend Maximum) This is the maximum time that can be added to the phase/ped phase combination when you are using Green Extend modes 0, 1, 3, and 4. The time to be added to the split when the phase’s TSP action is Called. GRN RED — (Green/SDW Reduction Maximum) When a phase is allowed to TSP Reduce by the Run settings, this is the maximum time that each split is allowed to be reduced, in seconds. This is the maximum time that can be reduced using a shortened solid Don’t Walk ped phase for this split. WLK EXT — (Green/Walk Extension Maximum) The maximum amount of time that can be added to the Walk portion of the phase when the TSP Request is Called before the end of the Walk portion of the associated Pedestrian phase. This is only used when you’ve set the run to use Green Extend modes 2, 3 or 4. The extra time will be added to the Walk portion of the associated Pedestrian phase. WLK RED — (Green/Walk Reduction Maximum) When a phase is allowed to TSP Reduce by the Run settings, this is the maximum time that each split is allowed to be reduced, in seconds, using a shortened Walk phase for this split.

Note The Flashing Don’t Walk (FDW) portion of the Pedestrian phase will never be adjusted by any TSP operation.

TSP Status Monitoring

ATC-1000 Advanced Traffic Controller 287

TSP STATUS MONITORING

There are three Status screens that can be used to monitor the current state of TSP operations:

The Time of Day Status screen always shows the current TSP Action Plan assignment. (MAIN MENU > 1. STATUS > 5. TIME OF DAY)

The TSP Inputs Status screen shows the current TSP inputs, the status of each of the eight TSP Runs, the signal colors of all of the NEMA phases. (MAIN MENU > 1. STATUS > B. TSP > 1. INPUTS)

The TSP Outputs Status screen shows the TSP outputs, the Q Jump outputs, the default programmed splits, and the TSP adjusted splits. (MAIN MENU > 1. STATUS > B. TSP > 2. OUTPUTS)

USB Operations

ATC-1000 Advanced Traffic Controller 301

USB OPERATIONS

The USB port on the front of the ATC controller is typically used to move data, in the form of controller databases, log files, and firmware in to and out of the controller.

USB Menu The following menu will appear automatically whenever you plug a USB thumbdrive or other passive device into the USB port on the ATC controller. Note that the appearance of this menu does not interrupt the normal operation of the controller.

USB device detected – remove to exit >1.USB->DATABASE 4.CMU_LOG->USB 2.DATABASE->USB 5.UPS_LOG->USB 3.LOG->USB

Figure 273 – USB Menu

To select an option on this menu, use the green up and down arrow buttons on the controller keypad to move the ‘>’ cursor next to the object you want to select, then press the ENT key.

The entries on this menu do exactly what they describe; they move data from one location to another. The USB tag indicates whether data will be going to the USB thumbdrive (‘-->USB’) or coming off of the USB drive and being stored on the controller (‘USB-->’). The other object in each menu item specifies what type of data or file is being moved. Those items where multiple files may be available provide a second display that allows the operator to select which file should be transferred.

To get out of this menu and return to the Main Menu system of the controller, simply remove the USB device from the controller’s USB port.

Note The USB menu will not appear if the controller is already in the Diagnostics menu.

302 ATC-1000 Advanced Traffic Controller

Moving Databases Using a USB Drive The controller database, or the set of all operating parameters stored in the controller, can be stored on a USB thumbdrive to be copied from controller to controller, or to be stored and retrieved from a PC-based software system such as IQ Link or IQ Central.

To move a database from a USB drive to the Controller 1. If the USB device has not been formatted previously to work with Peek ATC

controllers, use IQ Link to format the USB device.

2. Place a copy of the database you want to use on the controller onto the USB thumbdrive. This can be done either by writing it there from IQ Link, storing it on the USB device out of IQ Central, or copying the database out of another controller onto the USB device.

3. Plug the USB drive containing the database into the controller to be updated.

4. When the USB Menu appears, make sure the cursor (‘>’) is pointing to USB-->Database and press the ENT button.

5. The controller will ask for verification: “Download astcFFFF ? ENT=Y ESC=N” The astcFFFF is the standard filename for a complete ATC controller database. If you agree that you want to overwrite all of the settings currently stored in your controller, press the ENT button. If you realize that you do not want to do this, press the CLR/ESC button to exit out of the copy process without overwriting the current database.

6. If you press ENT, the file will be copied into the controller and decompressed into memory. Note that the new settings will start to control the controller immediately.

7. Next, the controller will ask if you wish to “Download the IO Map?” Again, press the ENT button if you do want to overwrite the current I/O output mapping data to the controller, or press ESC if you do NOT want to overwrite these settings.

8. Finally, the controller will ask if you wish to copy over the USB Objects. Press ENT to copy those items into the controller. Press ESC if you wish to cancel that process.

9. You will be returned to the USB menu. Remove the USB drive from the port and verify that the new database values are in place and functioning.

To store the controller database on a USB drive 1. If the USB device has not been formatted previously to work with Peek ATC

controllers, use IQ Link to format the USB device.

2. Plug the USB drive into the controller.

USB Operations

ATC-1000 Advanced Traffic Controller 303

3. When the USB Menu appears, use the up and down arrow buttons on the controller to place the cursor (‘>’) next to DATABASE-->USB and press the ENT button.

4. If a database is already stored on the drive, you will be asked if you want to overwrite it. Press the ENT button to overwrite the database file currently stored on the USB thumbdrive, or press CLR/ESC to cancel out of the process.

5. If you press ENT to proceed with the write operation, the controller will report the action and then return you to the USB menu. Remove the thumbdrive from the USB port.

This completes the storage of a controller database onto a USB thumbdrive.

Moving Logs Using a USB Drive There are three types of logs stored on an ATC controller: Event logs (or just ‘LOG”), CMU logs, and UPS logs. You will have the option to choose which one to store on the USB thumbdrive in step 3 below.

1. If the USB device has not been formatted previously to work with Peek ATC controllers, use IQ Link to format the USB device.

2. Plug the USB drive into the controller.

3. When the USB Menu appears, use the up and down arrow buttons on the controller to place the cursor (‘>’) next to the menu item of the log file you want to store on the drive: You can either choose the LOG file (the event log), the CMU_LOG file, or the UPS_LOG file. When you’ve positioned the cursor on the menu item you want, press the ENT button.

4. Repeat the previous step if you wish to store one of the other types of log files onto the USB drive.

5. The controller will report the data transfer action and then return you to the USB menu. Remove the thumbdrive from the USB port.

This completes the storage of one or more log files onto a USB thumbdrive.

Chapter 10 — Configuration and Maintenance

304 ATC-1000 Advanced Traffic Controller

USB File System The directories and files stored on a thumbdrive to be used with a Peek ATC controller follow a standard arrangement and naming conventions. The file system is normally laid out like this:

Figure 274 – ATC USB thumbdrive file system

The ASTC_DATA_DISK file stored in the root directory tells the ATC controller and IQ Data that the thumbdrive has been formatted and arranged specifically for use with Peek ATC controllers.

The \USTC_data folder is where log data and controller database files are stored on the drive.

The \USTC_firmware folder is where firmware files for a Peek ATC controller are stored. If the filename starts with ‘natc’, then the firmware is intended for a NEMA-type ATC controller such as the ATC-1000 and ATC-2000. If the filename starts with ‘atc’, then the firmware is intended for a New York CBD-type ATC controller such as the ASTC 3000 or the Phase 2 IQ ATC controller. Each controller will only recognize the firmware files of the correct type when attempting to update the firmware on that controller.

Chapter 10 — Configuration and Maintenance

310 ATC-1000 Advanced Traffic Controller

SYSTEM MAINTENANCE

Preventive Maintenance and Calibration The ATC-1000 controller is designed to require minimum maintenance, however, certain simple steps should be taken to insure proper operation. It is a good idea to periodically check the unit’s wiring, terminals, and connectors for signs of breakage and wear. Replace, if necessary. Vacuuming dust out of the unit and cleaning the front panel is a valuable step in maintaining good air circulation.

The controller should also be checked after it has been installed for six months, and then at least annually thereafter. Once the initial check is performed, a regular interval for preventive maintenance should be established based on the install and environmental conditions. During such a maintenance visit, the following procedures should be performed: Check all wiring connections for tightness, corrosion, damaged insulation, etc. Check all mounting hardware for proper tightness. It is also recommended that the controller’s software be updated with the latest revisions, when updates are warranted. This will allow more efficient and trouble-free operation. Contact your Peek Traffic support representative to find out if updated firmware is available.

Diagnosing Controller Operation Heartbeat LED

A 3mm RED LED is located on the front panel just above and to the right of the USB port. This will flash about twice per second to indicate that the controller’s microprocessor is functioning. It will double its flash rate whenever the operator makes changes to the controller database. If it is lit continuously, this indicates that the controller CPU has stalled.

Important When the LED flashes in this ‘double-speed’ mode, be sure to allow it to finish the

memory write operation before you attempt to navigate the menus or make further changes to the database.

PC Communications The controller must be powered up and in its normal operating mode in order to communicate with a PC. When having problems establishing communications, check the LEDs above the port to see if communications are occurring. If none are, or no connection can be established, be sure the controller’s port settings (baud rate, bit length, etc.) are set correctly in the controller’s Main Menu > Configuration > Comm Ports & IP/Cab Setup menu, and make sure they match the settings of the computer’s COM port and within the PC application being run (i.e. IQ Link, HyperTerminal, IQ Central, TransSuite, etc.)

Troubleshooting

ATC-1000 Advanced Traffic Controller 311

TROUBLESHOOTING

When a failure occurs during normal operation, after isolating the problem, most problems can be corrected using a screwdriver, a multimeter and/or simply replacing the CPU board. The most common problems are directly related to loose connections or broken wires. After that, the you may have a failed ATC CPU board. The controller diagnostics will easily notify you if the controller has a problem. If the controller is suspected, run its diagnostics and note any failures.

All procedures relative to good troubleshooting techniques should be followed. Also refer to the suggestions in “Table 25 – Troubleshooting the ATC-1000 Controller” on page 311.

Clearly identify the problem.

Verify fuse conditions.

Check all breakers for proper position.

Visually check all cables, harnesses and plugs for loose or worn connections.

Replace defective parts as required.

When troubleshooting, refer to the cabinet prints and parts lists.

If a defective ATC Controller module is found, contact your local service representative or a Peek Traffic service representative (see page 3 for contact information) so you can arrange to repair or replace the faulty unit.

Troubleshooting

ATC-1000 Advanced Traffic Controller 313

Troubleshooting Transit Signal Priority Operation There are two areas of TSP troubleshooting we’ll address. First, when setting up TSP for the first time, it can be a bit confusing and it is possible to miss a step that prevents TSP from operating.

Getting Up and Running

Here is a simple list of items that might prevent TSP from functioning when you first set up the function:

Are the signal lines from the transit vehicle sensor correctly wired to the controller inputs?

Is the TSP master Enable switch tuned ON? (MAIN MENU > 2.PROGRAMMING > 8.TRANSIT SIGNAL PRIORITY > 1.UNIT PARAMETERS > TSP ENABLE = ON)

Is TSP set up to expect the correct input type from your transit vehicle detection system. (MAIN MENU > 2.PROGRAMMING > 8.TRANSIT SIGNAL PRIORITY > 2. RUN PARAMETERS > INPUT MODE VALUES)

Is the correct TSP Action plan being called in your Time of Day schedule? (MAIN MENU > 2.PROGRAMMING > 4.TIME OF DAY > 1.ACTIONS > TSP = ACTION PLAN #)

Does the currently active TSP Action Plan have the correct Runs enabled? (MAIN MENU > 2.PROGRAMMING > 8.TRANSIT SIGNAL PRIORITY >3. ACTION PLAN (PICK THE CORRECT PLAN) > RUN ENABLE = “X”)

Does the currently active TSP Action Plan call the correct Run Configuration? (MAIN MENU > 2.PROGRAMMING > 4.TIME OF DAY > 1.ACTIONS > TSP = ACTION PLAN #)

Is the Run calling the correct phase or phases for Green Extension? (MAIN MENU > 2.PROGRAMMING > 8.TRANSIT SIGNAL PRIORITY > 4.RUN CONFIGURATION > DWN OR UP SO RUN = TSP INPUT # > CALLS = PHASES TO EXTEND)

Is the TSP Split Table for that Phase properly configured with extension and reduction times? (MAIN MENU > 2.PROGRAMMING > 8.TRANSIT SIGNAL PRIORITY > 6. SPLIT TABLE > SWITCH TO TSP SPLIT THAT CORRESPONDS TO THE SPLIT TABLE THAT IS BEING CALLED BY THE CURRENT ACTIVE PATTERN > VERIFY TIMES)

Chapter 11 — Controller Specifications

318 ATC-1000 Advanced Traffic Controller

OVERVIEW OF CONTROLLER SPECIFICATIONS

The ATC-1000 is a modular, standards-based controller that uses an Freescale Power Quix 2 hardware platform with memory management unit and floating point capabilities. It uses the Linux operating system with memory management for process isolation and to ensure operational integrity. The Peek line of ATC controllers fully support NEMA TS2 Type 1 and TS2 Type 2 functionality and are compliant with NTCIP 1201 and 1202. It has 3 built-in front panel serial ports, two 10/100 Base-T Ethernet ports, a high speed SDLC port for communications to the cabinet BIU(s) and MMU 2070-compatible modem slot with full modem flow control support can be installed. A high speed USB2 port is standard.

All of the ATC timing functions and clocks are referenced to the 60 Hz AC power line when AC power is available. Thus, the ATC’s timing will track any frequency drift of AC power.

The ATC does not use a battery backup for memory storage or the real time clock. All static memory (SRAM) and the real time clock are powered by 2 super capacitors, which provide sufficient power to operate the SRAM and clock functions of the controller for up to 7 days without AC power. Programs and operation database information is stored and preserved indefinitely in non-volatile flash memory.

The controller continuously monitors the STOP TIMING function from a conflict monitor, CMU or MMU. It uses the transition from ON to OFF to resume proper traffic operation. The ATC also sends a watchdog signal (CVM) to the cabinet conflict monitor or fault monitor to MMUs, which keeps the cabinet from going into FLASH condition.

The ATC enforces a minimum time of 3 seconds for each yellow signal. A shorter time for any yellow signal is not allowed because the CMU identifies a short yellow time as a fault and would automatically put the cabinet into FLASH. This minimum time value is preset in the CMU (2.7 seconds) and is called out in the CMU specification.

The Peek ATC controllers can be interrogated by a Microsoft Windows®-based software package known as IQ Link™ running on an external computer for setting and retrieving data from the unit via the front panel serial or Ethernet ports. This same capability is also available from Peek’s central system software package: IQ Central™. The front panel display and keypad can be used to view the status of the controller, view most of the available program parameters, and also to modify the programming of the unit.

The ATC-1000 and ATC-2000 feature dual traffic applications for pre-timed or NEMA Actuated operation. These applications are fully NTCIP-compliant implementations that easily integrate into any NTCIP-compliant ITS or traffic control system.

Chapter 11 — Controller Specifications

320 ATC-1000 Advanced Traffic Controller

NTCIP Compliance The Peek ATC controllers use Port 1 and the Ethernet ports to communicate with the central computer using NTCIP (National Transportation Communications for ITS Protocol). NTCIP conforms to NEMA TS2-2003 for Pretimed Type 1 (P1N Level 2) controllers.

NTCIP communications protocol and the full object set have not yet been completely specified. The NTCIP communications support adheres to the following timing constraints: whenever a message is received by the controller and that requires the controller to respond, (e.g. all messages except a broadcast message) the controller will initiate its response (i.e., start the transmission of data) within 40 ms. Further, the data is transmitted continuously (i.e., no gaps between characters) until the transmission is complete.

Once-per-second communications will be critical to the central management of the controllers. NTCIP relies on “dynamic object” capability to allow the central computer to program a list of data items to be returned in response to a “short-hand” request. The controller will support dynamic objects.

In order to support the uploading and downloading of the controller database over relatively slow channels, the controller supports the concept of “logical blocks”. Peek Traffic and US Traffic have defined NTCIP manufacturer proprietary objects that encapsulate a group of data elements (e.g., phase timings block, coordination plan block, detector configuration block, etc.). By grouping the objects into blocks, the number of objects to transfer is reduced, and, since the bulk of the NTCIP overhead is in the object headers and identifiers, transfer time is much more sensitive to the number of blocks than to the size of each block. However, the storage medium and update procedures do not interfere with rapid data transfer. Upon receipt of a database download block, the controller responds within the timing envelope described. In addition, the receipt of multiple database download blocks in rapid succession does not result in any communications errors, NTCIP (SNMP) error codes, or communications turn-around delays.

USB CONNECTORS

The single USB (Universal Serial Bus) port on the front of the ATC-1000 controller is a standard USB 2.0 port and will accept any standard USB RAM device. Devices can be ‘hot swapped’ into and out of this USB port just like on a PC.

PIN Function Cable Color 1 +VCC Red

2 Data – White

3 Data + Green

4 GND Black

The USB port on Peek ATC controllers follow the Universal Serial Bus standard and improve plug-and-play capabilities by allowing devices to be hot swapped or added to the system without rebooting the controller. When a new device first plugs in, the host board enumerates it and loads the device driver necessary to run it. The loading of the appropriate driver is done using a PID/VID (Product ID/Vendor ID) combination supplied by the attached hardware. The USB host controller in the Peek ATC controllers uses the EHCI (Enhanced Host Controller Interface), meaning it is compatible with USB 2.0 devices, however the Controllers will only recognize passive USB devices such as RAM or Flash memory devices, but not cameras, external hard drives, or other active devices.

The USB specification limits the cable length of a cable between full speed devices to 16 feet, 4.8 inches (5.0 meters). For low speed devices, the computer cable limit is 9 feet, 10 inches (3.0 meters).

NEMA TS2 TYPE 2 I/O MODULE

The ATC’s NEMA TS2 Type 2 I/O module has three standard connectors for attaching the controller to the cabinet hardware. The three connectors are keyed circular MilSpec Amphenol connectors, each with a different pin count. They are known, from left to right, as Connectors A, B, and C, and they are described in the next three topics.

Port A Connector Port A is a standard of the NEMA TS2 Type 2 controller specification. It is a circular keyed male pin MilSpec connector with 55 pins in the following arrangement:

Figure 291 – Pin assignment, looking INTO the male Port A connector

These are the pin function assignments for the Port A connector when the ATC-1000 controller is operating in its default input/output mode (i.e. Mode 0). For details on switching to one of the other input/output modes, refer to “Alternate Input/Output Mode Selection” on page 334.

Alternate Input/Output Mode Selection A TS2 Type 2 controller can map the outputs on its A, B and C connectors in a number of ways. Three of the pins on the Port A connector are used to define the input/output mode that the controller will operate in. This mode selection is part of the standard for a NEMA TS2 Type 2 controller. These modes determine which pin on the four cabinet connectors are used for which function. As with all of these inputs and outputs, the inputs used to set the mode follow the NEMA signal standard, i.e. TRUE = 0VDC and FALSE = 24VDC.

Table 36 – To set the TS2/2 Input/Output Mode, set these inputs to these values:

When the ATC-1000 controller is switched to one of the other Input/Output modes, some, but not all, of the default pin function assignments on the Port A, B, and C connectors are modified. These changes are listed in the next two tables. The ATC-1000 auto-recognizes each “D” module and self-activates Mode 7.

OVERVIEW

This chapter describes the pinouts of the various Peek ATC controller D modules.

ATC D MODULE

Port D is only defined in the NEMA TS2 Type 2 controller specification as an optional MilSpec connector whose size, pin arrangement, and pin functions can be set by the manufacturer. In the case of the ATC-1000 controller, Port D is a circular keyed male pin MilSpec connector with 61 pins in the following arrangement:

Figure 299 – Pin assignment, looking INTO the male Port D connector

These are the pin function assignments for the Port D connector. Note that when the ATC-1000 controller is operating in its default input/output mode (i.e. Mode 0), the Port D connector is disabled. The controller must be placed in Mode 7 for the Port D pins to become active. For details on switching to one of the other input/output modes, refer to “Alternate Input/Output Mode Selection” on page 334.

As with the inputs and outputs on the other cabinet connectors, the inputs and outputs on the Port D connector follow the NEMA signal standard, i.e. TRUE = 0VDC and FALSE = 24VDC.

Glossary

3000E — A traffic controller produced by Peek Traffic Corporation.

AC — Alternating Current

Actuated — Identifies a type of controller which responds to calling signals generated by the actions of either vehicles or pedestrians. See also Semi-actuated and Fully-actuated.

Adaptive Split Control — A means of intersection split selection based on vehicular activity.

ADC — Analog-to-Digital Converter

ACD, Advance Call Detector — A detector located a considerable distance upstream from an intersection which calls the green to that approach.

AW, Advance Warning — A per-movement output used to give advance notice of an upcoming yellow or red indication. Typically used at hidden intersections with “prepare to stop” indicators.

ASCII — American standard code of information interchange. A standard code that assigns eight-bit codes to individual alphanumeric characters.

ASTC — Advanced Solid State Traffic Controller: the name given to a controller design specified by New York City DOT. This acronym was chosen to distinguish it from the more general ATC standards development program. The ATC-1000 controller is an ASTC controller.

ATC — Advanced Traffic Controller, a design developed per the ATC standards development program of the State of California and the Federal Highway Administration. Requires the controller to have a separate engine board and run the Linux operating system. The ATC-1000 controller is not an ATC controller.

Glossary

CIC — Critical Intersection Control

Clearance Interval — The interval from the end of the right-of-way of one phase to the beginning of a conflicting phase.

Closed-Loop System — A software and hardware system in which a computer controls an external process using information received from the process. For example, the closed loop in a traffic control system is from the computer to the controllers and then from the detectors back (through the controller) to the computer.

CLR — Phase Clearance. Includes Ped Clearance times for CNA phases.

CMU/MMU — Conflict Monitor Unit – Also known as MMU (Multifunction Management Unit). This device monitors the green, yellow, and red AC loadswitch outputs for conflicts, the absence of a proper red signal and the watchdog signal from the controller. Any real and potential unsafe condition will force the cabinet into flash.

CMOS — Complementary Metal Oxide Semiconductor – a type of integrated circuit chip used on electronic boards.

CNA — Call to Non-Actuated. Provides a method of phase timing where vehicle and pedestrian detectors are not required to serve the associated phases, with operation as defined by NEMA. An actuated controller feature in which the associated phase will always serve the Walk plus Ped Clear time, regardless of detector inputs.

Compatibility Line — The dividing line crossing both rings (in dual ring operation) that separates compatible phase combinations. Usually, it divides phases associated with North/South from those associated with East/West. Also known as the Barrier.

Conditional Service — A dual-ring feature which allows re-service to an odd phase (i.e. a left turn phase) once the opposite ‘through’ phase has gapped out. The service is conditional upon the time remaining in the adjacent ‘through’ phase’s Max timer.

Conflict Monitor — A device used to continually check for the presence of conflicting signal indications coming from the controller, and to provide an output in response to the conflict (usually All Flash).

Conflicting Phases — Two or more traffic flows which would result in interfering traffic movements if operated concurrently.

Controller — A device which, through software and firmware programming, manages the sequence and duration of traffic signals.

CRD, COORD — Coordination

Glossary

360 ATC-1000 Advanced Traffic Controller

Coordination — The state where two or more intersections are configured to communicate with each other in order to time their signals in some manner that improves the greater system performance, rather than being timed independently at each intersection. This independent operation, by contrast, is known as Free operation.

CU — Controller unit, in some standards documents, notably those from the States of California and New York in the United States, traffic controllers are often refered to by this two-letter acronym. Occasionally, this abbreviation sneaks into the documentation from Peek.

CVM — Controller voltage monitor. An open collector output that is maintained ‘low’ by the controller as long as the internally generated operating voltages are within tolerances. This output is used by a conflict monitor to place the intersection in Flash, should all voltages fail in the controller.

Cycle Zero Point — See ‘Time Reference Point’

Database — Traffic controllers and central system software typically uses two distinctly different meanings for the term ‘database’. The first is the typical one used in most computer systems: a central system stores and maintains all of the information it gathers from the field about all connected controllers in a set of database files on the central computer. The second meaning of database is the complete set of operating parameters stored in a single controller or master controller.

Density — A measure of the concentration of vehicles in an intersection, stated as the number of vehicles per mile (space density) or as the flow volume divided by the average speed (point density.)
