INTRODUCTION

• Overview of the ATMS in Central Broward Design Build Project– RFP and Minimum Technical Requirements– Design process– Design Complexities – Integration/Implementation Plan

• FDOT and Broward County’s Plan for Arterial Operations

GOAL OF THE PROJECTImprove the efficiency of the existing

Transportation system through:– Establish a System for Real Time Performance

Monitoring• Detect the causes of non-recurring congestion• Understand the recurring congestion patterns

– Active Arterial Management• Incident management• Traveler information dissemination • Signal retiming

4

ATMS BENEFITS• Increased motorists awareness of travel time and vehicular incidents• Emergency Pre-Emption and transit signal priority will allow

emergency vehicles and buses to travel faster, safer • Improved incident response time through early detection• Data collected used to adjust traffic signals to improve timing and

flow of traffic• Reduced fuel consumption• Reduced emissions• Reduced accidents caused by congestion, speed differential and

sudden lane changing• Reduced in secondary accidents• Reduced delays • Increased average travel speed• Increased trip reliability

PROJECT AREA

ATMS IN CENTRAL BROWARD COUNTY

Project Components– 31.8 miles of fiber optic

communication infrastructure– Closed Circuit TV (CCTV) Cameras– Arterial Dynamic Message Signs

(ADMS)– Opticom devices for emergency

pre-emption and Transit Signal Priority System (TSPS) devices

– Microwave Vehicle Detection Sensors (MVDS)

– Travel Time System (TTS) readers (AVI and Bluetooth)

Construction Timeline • Summer 2012-Fall 2013• COST: $8.9 million • Contractor: World Fiber

Technologies, Inc.• Lane Closures:

– Limited impact on the communities surrounding and within the project limits.

ATMS IN CENTRAL BROWARD COUNTY - DEVICES

Arterial DMS

MAC Address matching system for travel time and origin destination measures (on new poles or existing mast arms)

CCTV and MVDS on Poles and Existing Mast Arms

AVI Travel Time System

• Key MTR Requirements– 100% CCTV camera coverage– Cameras to be mounted on poles with lowering devices

• Providing complete camera coverage– Bucket truck survey to replicate installed camera

video.

DESIGN PROCESS

DAYTIME VIDEO

10

NIGHTTIME VIDEO

• MVDS midblock spacing• Travel time sensor spacing at origin and destination

points (also at DMS locations)

DESIGN COMPLEXITIES

New DMS locations

TT Detectors and MVDS locations

• Design variation was required due to mounting proposed CCTV cameras on existing trusses and mast arms– Structural analysis required on existing mast arms selected for

camera mount per PPM 25.4.26

• Release of underground conduit and pull box component plan set to expedite construction.

DESIGN PROCESS (CONT’D)

• Utility Coordination with numerous utility owners

• Proposed device locations do not interfere with existing overhead and underground utilities– Design and construction Subsurface Utility Engineering

(SUE) investigation was utilized to achieve this.

• Verification of existing fiber optic infrastructure to connect with the proposed ATMS network

DESIGN PROCESS (CONT’D)

• Co-locating ATMS devices where feasible to reduce construction costs

• Permit approval process with local permitting agencies

DESIGN PROCESS (CONT’D)

INTEGRATION AND IMPLEMENTATION

• SunGuide to run ITS devices– Developed new plugin for BlueTOAD travel time and

origin destination reports (provides real time input into SunGuide for TMC operators)

– AVI module to be used in conjunction to compare technologies

– New H.264 video stream driver– All ITS devices are to be integrated and tested in

SunGuide

• Signal System is separate– Opticom integrated into signal system

• Device location acceptance before substantial design starts• Underground conduit and pull box component set was

released to start construction• Double stack concept plans not preferred, little room for

details

LESSONS LEARNED

OPERATIONS AND MAINTENANCE OF ATMS: AFTER ATMS IS COMPLETE, NEXT STEPS

• Fall 2013• Partnerships – FDOT and Local Agencies– Capitalize on strengths and pool resources

• Master Plan for Defined Network• Development of Arterial Management Process– Palm Beach County Living Laboratory– Research projects

18

PARTNERSHIPS

• Operations and Maintenance• Agency strengths and resources to be pooled for

maximum efficiency• In house skills, ITS devices and ATMS software

• Investigate ways for FDOT District 4 to enhance arterial O&M programs

• Objective – performance based arterial O&M program

1. Method for reporting demand is defined

2. Identify Critical Trends

3. Identify demand Thresholds

4. What can we do to prevent /alleviate network breakdown? When should these strategies

be implemented?

5. How do the

strategies impact the network?

6.Demonstrate

Demand Based Signal Retiming

19

PARTNERSHIPS• Research underway in which local

agencies co-manage with FDOT– Demand Based Signal Retiming– Coordinated Pre-Preemption of

Traffic Signals to Enhance Railroad Grade Crossing Safety in Urban Areas and Estimation of Train Impacts to Arterial Travel Time Delay

• Both focus on using existing tools (signal system, system software and data collection devices)

20

EXPANSION OF ATMS ON A DEFINED NETWORK• Freeway ITS + Arterial ATMS• Partnership with local agencies

PALM BEACH COUNTY LIVING LAB

• The principle goal for the TSM&O “Living Laboratory” is to begin the utilization of TSM&O principles in a controlled environment for a limited number of arterial roadways in order to identify key elements and the requirements of the process.

• Accomplished through PBC and FDOT partnership• Primary Deliverable: Scalable SOGs that can be applied in

Broward County

PALM BEACH COUNTY LIVING LAB

• Starting with a plan with clear objectives and targets– Sample:

Define Scalable Standard Operating Guidelines for Active Arterial Management

1. Establish a monitoring plan to allow for TSM&O operator to provide initial notification to the County (example, cameras are reviewed every hour). Performance metrics are defined as possible. 2. Analyze the scalability of the monitoring plan3. Document findings and Recommendations for improving the monitoring plan for automation on daily logs4. Analyze daily logs and establish performance targets5. Daily analysis of problem areas and recommendations are made for improving performance and automating analysis of problem areas

1. Initial plan developed and implemented by September 28th, 2012. Plan improvements are recommended by operator in bi-weekly meetings. 2. To run concurrent with development of operations contract - February 1st, 2013Steps 3 - 5 are documented in Daily Logs and are reviewed in weekly status meetings.

ASSESSING PROGRAM EFFECTIVENESS

• Palm Beach County Living Laboratory– Develop active management strategies– Develop arterial performance measures– Develop interagency partnerships & coordination– Deliverable: Scalable SOGs

24

PALM BEACH COUNTY LIVING LAB• Accomplishments to date– Created an event management database– Started the development of a plugin to interface with FL

511 (without SunGuide)– Investigating existing plugins for use to connect arterial

Travel Time information to FL 511 (without SunGuide)– Started operating arterials with PBC in early October

2012• 7am to 7pm, operator follows monitoring plan• Weekly reports • Performance Dashboard and Business Plan updated monthly
