HART Bus Rapid Transit (BRT) Expansion

Project Description: This project would create new Bus Rapid (BRT) lines, running from east to west, in Hillsborough County. These lines would intersect the currently deployed BRT lines. The deployment would include transit signal priority at additional intersections.

Project Status: Planned

Project Stakeholders:

• City of Tampa Smart Mobility Division
• County Public Safety Agencies
• Hillsborough Area Regional Transit Authority (HART)
• Hillsborough County PWD

Project Service Packages:

• PT09: Transit Signal Priority (HART BRT Expansion)
• PS03: Emergency Vehicle Preemption (HART BRT Expansion)

Project Functional Requirements (Element - Functional Object):

• City of Tampa Field Equipment - Roadway Signal Control
• 1: The field element shall control traffic signals under center control.
• 10: The field element shall receive request for transit vehicle signal priority.


• City of Tampa Field Equipment - Roadway Signal Preemption
• 1: The field element shall respond to signal preemption requests from emergency vehicles.


• City of Tampa TMC - Emergency Routing
• 9: The center shall provide the capability to request special traffic control measures, such as signal preemption, from the traffic management center to facilitate emergency vehicle progress along the suggested route.


• City of Tampa TMC - TMC Basic Surveillance
• 1: The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements under remote control of the center.


• City of Tampa TMC - TMC Signal Control
• 1: The center shall remotely control traffic signal controllers.
• 10: The center shall adjust signal timing in respond to a signal prioritization, signal preemption, pedestrian call, multi-modal crossing activation, or other requests for right-of-way.


• County Fire EMS/Rescue Vehicles - EV On-Board En Route Support
• 2: The emergency vehicle, including roadway service patrols, shall send the vehicle's location and operational data to the center for emergency management and dispatch.
• 5: The emergency vehicle shall send requests to traffic signal control equipment at the roadside to preempt the signal.


• HART Transit Vehicles - Transit Vehicle Signal Priority
• 1: The transit vehicle shall determine the schedule deviation and estimated times of arrival (ETA) at transit stops.
• 2: The transit vehicle shall send priority requests to traffic signal controllers at intersections, pedestrian crossings, and multimodal crossings on the roads (surface streets) and freeway (ramp controls) network that enable a transit vehicle schedule deviation to be corrected.


• Hillsborough County Field Equipment - Roadway Signal Control
• 1: The field element shall control traffic signals under center control.
• 10: The field element shall receive request for transit vehicle signal priority.


• Hillsborough County Field Equipment - Roadway Signal Preemption
• 1: The field element shall respond to signal preemption requests from emergency vehicles.


• Hillsborough County Traffic Management Center - TMC Basic Surveillance
• 1: The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements under remote control of the center.


• Hillsborough County Traffic Management Center - TMC Signal Control
• 1: The center shall remotely control traffic signal controllers.
• 10: The center shall adjust signal timing in respond to a signal prioritization, signal preemption, pedestrian call, multi-modal crossing activation, or other requests for right-of-way.
