District 4

Broward, Palm Beach, Martin, St. Lucie and Indian River counties make up District 4’s 5,000 square miles. With 3,615,400 residents. Vehicles in District 4 travel more than 52.4 million miles daily.

District 4 is served by 91 airports, three deep-water ports, and two railroads. FDOT provides assistance to Tri-Rail (a commuter rail service), to Gold Coast Commuter Services (a commuter assistance program) and to two major transit authorities (Broward County Transit and Palm Tran) with 319 passenger vehicles.

Regional Projects

Express lanes are being implemented within District Four to address existing congestion, enhance transit services, accommodate future regional growth, and improve system connectivity between key limited access facilities. In Florida express lanes are a type of priced managed lane where congestion is managed with dynamic tolling, limited access, and limited eligibility. Express lanes are co-located within an existing facility to manage congestion and provide a more reliable trip time.

Operators at the SMART SunGuide Regional Transportation Management Center (RTMC) monitor the Express Lanes 24 hours per day, 7 days per week. They utilize Intelligent Transportation Systems (ITS) technologies and related computer software to monitor traffic volumes and calculate dynamic toll rates. Sensors on the road provide continuous information about how many vehicles are in the express lanes and how fast they are going. Based on this information the toll rates are increased or decreased to proactively manage the number of vehicles that enter the express lanes and prevent them from becoming congested. The goal is to keep the express lanes operating at free-flow speeds at all times.

Enhanced incident management procedures have also been implemented to support the express lanes projects. RTMC Operators coordinate with responders to provide faster clearance times of travel lane blocking events such as crashes, debris or disabled vehicles. They coordinate with and dispatch any appropriate resources, including: Road Ranger Service Patrols, Severe Incident Response Vehicle Operators and any others needed to manage the incidents and restore the highway back to its regular operating conditions.

I-95, I-75 and I-595 are part of a larger network of existing and planned congestion priced managed lanes in southeast Florida. In order to maximize the benefits of managed lanes, FDOT will develop projects on individual roadway corridors as part of an overall connected Managed Lanes Network. These individual Managed Lanes projects would be linked and interconnected to function and operate as a seamless regional managed lanes network to provide improved mobility, reliability, and trip options throughout the region.
