The THEA Connected Vehicle Pilot will employ innovative vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication technology to improve safety and traffic conditions in downtown Tampa.
Roadways: Lee Roy Selmon Expressway
As westbound commuters approach the downtown terminus of the Lee Roy Selmon Expressway’s Reversible Express Lanes, they enter a sharp curve ending at a traffic light at the intersection of East Twiggs Street and Meridian Avenue. Morning traffic backs up at this intersection, increasing the risk of rear-end crashes. Drivers on the express lanes who participate in the THEA Connected Vehicle Pilot will receive warnings when motorists on the road ahead have suddenly slowed down or come to a stop. Their vehicles will also alert them when they are approaching the curve at an unsafe speed.
Roadways: Lee Roy Selmon Expressway, East Twiggs Street, North Meridian Avenue
The downtown terminus of the Lee Roy Selmon Expressway’s Reversible Express Lanes is a potential entry point for wrong-way drivers. The THEA Connected Vehicle Pilot aims to reduce the risk of collisions by detecting and warning wrong-way drivers before they get on the expressway. Other connected vehicles on the express lanes will also receive warnings when a wrong-way driver is approaching.
Roadways: East Twiggs Street
The THEA Connected Vehicle Pilot will install connected vehicle technology at the midblock crosswalk on East Twiggs Street at the Hillsborough County Courthouse to improve pedestrian safety. When sensors detect a pedestrian in the crosswalk, roadside equipment will broadcast that information to connected vehicles in the vicinity, and their drivers will receive an alert.
TRANSIT SIGNAL PRIORITY
Roadways: North Marion Street, East Kennedy Boulevard, East Jackson Street
The THEA Connected Vehicle Pilot will outfit 10 Hillsborough Area Regional Transit (HART) buses with equipment that will enable them to communicate with traffic signals on their routes. Downtown traffic congestion can prevent HART buses from reaching their stops on time, causing them to fall behind schedule. The signals will prioritize bus movements when necessary to keep buses on schedule.
Roadways: Channelside Drive
The TECO Line Streetcar System is an electric trolley line that roughly follows Channelside Drive between downtown Tampa and Ybor City. The THEA Connected Vehicle Pilot will equip TECO Line streetcars with devices that enable them to communicate wirelessly with other connected vehicles and pedestrians. Streetcar operators will receive a warning when a connected vehicle or pedestrian is about to cross the track, reducing the risk of a collision.
Roadways: Meridian Avenue, North Nebraska Avenue, Florida Avenue
Connected vehicles will communicate with some traffic signals on Meridian, North Nebraska and Florida avenues to optimize signal timing and improve traffic flow based on real-time traffic conditions. Drivers of connected vehicles will also receive a warning when it is not safe to enter an intersection. For example, the car can alert its driver to oncoming traffic on a cross street that may be out of the driver’s view. The City of Tampa’s Traffic Management Center will also capture traffic data to improve system-wide performance.
