Advanced Transportation Management System (ATMS) in Central Broward County
Melissa Ackert, E.I. FDOTMatt Wilson, P.E. Jacobs Engineering
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
3
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
