Sarasota County BRT

Project Description: This project would create a dedicated lane for buses on the Ringling Causeway. Currently, there is a breakdown lane on the causeway, which would be converted to a bus–only lane. In addition, this project may include transit signal priority for buses.

Project Status: Planned

Project Stakeholders:

• Manatee County Area Traffic Agencies
• Sarasota County Area Transit
• Sarasota County Public Works Department

Project Service Packages:

• PT09: Transit Signal Priority (Manatee County MCAT)

Project Information Flows:

Information Flow	Source Element	Destination Element	Status
local signal priority request	Sarasota County SCAT Fixed Route Transit Vehicles	Sarasota County Field Equipment	Planned
right-of-way request notification	Sarasota County Field Equipment	Manatee-Sarasota Regional Traffic Management Center	Planned
signal control commands	Manatee-Sarasota Regional Traffic Management Center	Sarasota County Field Equipment	Planned
signal control commands	Sarasota County TMC	Sarasota County Field Equipment	Planned

signal control status	Sarasota County Field Equipment	Sarasota County TMC	Planned

Project Functional Requirements (Element - Functional Object):

• Manatee-Sarasota Regional 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.


• Sarasota County Field Equipment - Roadway Basic Surveillance
• 1: The field element shall collect, process, digitize, and send traffic sensor data (speed, volume, and occupancy) to the center for further analysis and storage, under center control.


• Sarasota 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.


• Sarasota County SCAT Fixed Route 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.


• Sarasota County 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.


• Sarasota County 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.
