StarMetro Transit Signal Priority

Project Description: This project would upgrade StarMetro buses to allow Opticom–style transit signal priority (TSP).

Project Status: Planned

Project Stakeholders:

• City of Tallahassee
• County and City Traffic Engineering
• FDOT D3/City of Tallahassee
• StarMetro

Project Service Packages:

• PT09: Transit Signal Priority (StarMetro Transit)

Project Information Flows:

Information Flow	Source Element	Destination Element	Status
intersection status	City of Tallahassee Field Equipment	FDOT District 3 Road Ranger Service Patrol Vehicles	Planned
local signal priority request	StarMetro Transit Vehicles	City of Tallahassee Field Equipment	Planned
local signal priority request	StarMetro Transit Vehicles	County and Local Field Equipment	Planned
right-of-way request notification	City of Tallahassee Field Equipment	City of Tallahassee STMC	Planned

Project Functional Requirements (Element - Functional Object):

• City of Tallahassee 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 Tallahassee STMC - 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 and Local 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.


• StarMetro Transit Vehicles - Transit Vehicle Signal Priority
• 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.

Standards:

• US: NTCIP Signal Priority - SNMPv3/TLS
• US: SAE Signal Preemption - WAVE TCP

Project Operational Concepts:

Roles and Responsibilities

• StarMetro
• Obtain traffic signal priority from the City of Tallahassee, the FDOT District 3 RTMCs, and county and city traffic systems using respective roadside field equipment for all fixed-route transit vehicles.


• City of Tallahassee
• Operate traffic signal systems, including CCTVs, signals, and sensors, for the City of Tallahassee. Utilize signal systems owned by county and local agencies, as well as FDOT District 3.
• Provide transit signal priority for StarMetro transit vehicles using roadside devices.


• County and City Traffic Engineering
• Operate traffic signal systems, including CCTVs, signals, and sensors, on county or local roadways.


• FDOT D3/City of Tallahassee
• Operate traffic signal systems in the City of Tallhassee and Leon County.
