Tampa (THEA) Pilot


THEA icon

Tampa-Hillsborough Expressway Authority (THEA) owns and operates the Selmon Reversible Express Lanes (REL), which is a first-of-its-kind facility to address urban congestion. The REL morning commute endpoint intersection is on major routes into and out of the downtown Tampa commercial business district. Drivers experience significant delay during the morning peak hour resulting in, and often caused by, a correspondingly large number of rear-end crashes and red light running collisions. Because the lanes are reversible, wrong way entry is possible. Just earlier this year, a wrong-way accident killed two people there. As shown in the figure below, the THEA pilot will deploy a variety of vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) applications (see Table 1) to relieve congestion, reduce collisions, and prevent wrong way entry at the REL exit. THEA also plans to use CV technology to enhance pedestrian safety, speed bus operations and reduce conflicts between street cars, pedestrians and passenger cars at locations with high volumes of mixed traffic.

The THEA CV Pilot will employ Dedicated Short Range Communication (DSRC) to enable transmissions among approximately 1,000 cars, 10 buses, 8 trolleys, and approximately 47 roadside units along city streets (see Table 2). To support this initiative, THEA will be working with their primary partners, The City of Tampa (COT), Florida Department of Transportation (FDOT) and Hillsborough Area Regional Transit (HART) to create a region-wide Connected Vehicle Task Force. The primary mission of this Task Force is to support the deployment of Connected Vehicle infrastructure in the region in a uniform manner to ensure interoperability and interagency coordination as these deployments transition from concept to planning to operations. While THEA plans to initiate this process, the intent is to work with the other partner agencies to ultimately host this task force, including funding the studies and administrative activities.
