About District Four TSM&O

What is TSM&O in District 4

The goal of District 4's Transportation Systems Management and Operations (TSM&O) program is to provide a framework for active management of its transportation network. Active management is already very mature on District 4’s freeways as a part of its Intelligent Transportation Systems (ITS) Program. Therefore, District 4's TSM&O Program's primary focus has been on performance-based arterial traffic management. This approach is based on many of the principles that guide District 4's ITS Program, such as:
  • Defining a network to be managed,
  • Defining performance indicators and targets,
  • Deploying and operating IT-based systems to manage traffic in real time,
  • Reporting performance outcomes, and
  • Improving performance.

Why South Florida needs TSM&O:

High fluctuations in travel-time variability due to urbanized over-congestion as well as inconsistent arterial operating methodologies (ITS and incident management) have become stressful upon the vast, populous metropolitan area. In 2001 the Texas Transportation Institute estimated that 75 of the largest metropolitan areas in the US experienced 3.5 billion vehicle-hours of delay, resulting in 5.7 billion gallons in wasted fuel, and $69.5 billion in lost productivity (The Operations Story, USDOT-FHWA April 2004). Further studies have shown that consistent traffic signal retiming (one of many TSM&O strategies/tools) alone can lead to millions of dollars in savings in heavily congested areas over time (The Benefits of Retiming Traffic Signals, ITE Journal, April 2004).

Where will TSM&O be implemented?

In October 2012, District 4 partnered with the Palm Beach County Traffic Division and its contractors and started an arterial management pilot project along a network of six corridors in Palm Beach County. Deemed the “Palm Beach Living Lab,” this ever adapting and evolving initiative was intended to help refine management strategies and break ground on incident management along arterial corridors. Using an array of ITS equipment, including cameras and vehicle data collection sites, engineers from the Palm Beach County Transportation Management Center are able to identify and mitigate the causes of congestion in real time.

Starting in November 2013, District 4 will add an additional six arterial corridors in Broward County to its arterial management program. Totaling just over 60 miles of managed roadway, FDOT will be able to provide intelligent solutions to traffic delays on a level not yet achieved in the state of Florida.

District 4 TSM&O Partners

Given today's advancements in transportation technologies, a jurisdictional mindset of the transportation system is an out-fashioned and inefficient approach to coordinating such a vastly connected area. A larger focus on the system as a whole, utilizing inter-agency technologies and practices, is vital for the successful daily operations of our transportation infrastructure. Interagency communication and cooperation is key to the success of the TSM&O program within District 4. The current participating municipalities include, but are not limited to:

  • Florida Department of Transportation
  • Broward Metropolitan Planning Organization
  • Broward County Traffic Engineering Department
  • Broward County Transit
  • Palm Beach County Traffic Engineering
  • PalmTrans
  • The City of Boca Raton
  • The City of Palm Beach
  • St. Lucie County

Existing and Proposed TSM&O Facilities

The TSM&O program’s overarching goal is to improve mobility of the existing transportation system through operating a defined network of arterials and limited-access facilities. TSM&O integrates and takes advantage of transportation system components, such as ITS, advanced transportation management systems (ATMS), parking management systems, ramp signals, and transit automatic vehicle location/computer-aided dispatch AVL/CAD systems. These systems are used to implement active traffic management strategies, such as work zone management, incident management, transit signal priority, and dynamic signal retiming along its monitored project corridors..

Limited-Access Facilities - ITS

Equipped, operated, and maintained by the District 4 Traffic Operations ITS Program. Facilities include I-95, I-595, and I-75. For detailed information, please visit the Smart SunGuide® web site at http://smartsunguide.com or project specific web sites at:

Temporary Video Image Detection Systems (VIDS) in 3R Projects

A national literature search was completed to identify other agencies that are currently using this practice and if they have standards developed. The result was that while agencies are doing this in some cases, no standards have been developed. As part of their research, the University of Southern Florida modeled three types of intersection configurations and prepared a technical memo on the cost/benefit of these intersection configurations: (1) 6 lanes x 6 lanes, (2) 6 lanes x 4 lanes, and (3) 4 lanes x 4 lanes located in Broward and Palm Beach Counties. The results of the research identified benefits in using temporary VIDS to maintain signal operations based on the length of the project under construction. General notes for inclusion in plans were developed for FDOT as part of this task.

Virtual Freight Network (VFN) – Freight Advanced Traveler Information System (FRATIS)

The South Florida VFN concept was developed by the South Florida freight stakeholders. It is a technology-based program designed to facilitate the movement of cargo between major load centers in South Florida – specifically, truck trips connecting seaports with rail yards and distribution centers, and airports with distribution centers. South Florida is proposing the following elements as a part of its VFN concept:
  • C-TIP functionality to maximize movements among key freight hubs,
  • Use of commercial vehicles as traffic probes to improve accuracy of traveler information,
  • Real-time traveler information to support real-time re-routing of commercial vehicles,
  • Virtual weigh stations to help improve safety and enforcement activities, and
  • Synchronized signal timing and truck priority.
The VFN concept was used to develop USDOT’s FRATIS Concept of Operations. Although not all aspects for the VFN were accepted, FRATIS will develop the following application bundles:
  1. Freight-Specific Dynamic Travel Planning and Performance
    This application bundle will include all of the traveler information, dynamic routing, and performance monitoring elements identified in the development of user needs for this project. The application will leverage existing data in the public domain as well as emerging private sector applications to provide benefits to both sectors.

  2. Intermodal Drayage Operations Optimization
    This application bundle will combine container load matching and freight information exchange systems to fully optimize drayage operations; thereby, minimizing bobtails/dry runs and wasted miles and spreading out truck arrivals at intermodal terminals throughout the day. These improvements would lead to corresponding benefits in terms of air quality and traffic congestion.
FRATIS is currently in the prototype testing phase in Dallas, TX; Los Angeles, CA; and South Florida. The South Florida prototype test has an added feature in which FRATIS is being developed with emergency evacuation situations in mind. During an emergency evacuation, communications becomes extremely important, not just with emergency and law enforcement agencies, but also with truck drivers providing supplies. FRATIS is expected to facilitate better communications between the critical users of the transportation network.
