Stakeholder Element Name Functional Area/Role Functional Area Description
MTA NYC Transit MTA NYCT Bus Command Center - Operations Transit Center Signal Priority The equipment package monitors transit schedule performance and generates requests for transit priority on routes and at certain intersections. This equipment package may coordinate with the Traffic Management Subsystem to provide transit priority along the selected route. It also coordinates with the Transit Vehicle Subsystem to monitor and manage local transit signal priority requests at individual intersections.
MTA NYC Transit MTA NYCT Buses On-board Transit Signal Priority This on-board equipment package provides the capability for transit vehicles to request signal priority at signalized intersections, ramps, and interchanges through short range communication directly with traffic control equipment at the roadside.
NYC DOT - Department of Transportation NYC DOT Field Equipment Roadway Signal Priority This equipment package includes the field elements that receive signal priority requests from transit vehicles approaching a signalized intersection. The request for priority may or may not be granted, based on the overall traffic situation at the intersection, adherence to the schedule of the transit vehicle, etc. If priority is granted, the operation of the traffic signal is adjusted to give an early green indication or hold a green indication that is already displaying
NYSDOT/NYCDOT/NYPD New York City Joint TMC TMC Signal Control This equipment package provides the capability for traffic managers to monitor and manage the traffic flow at signalized intersections. This capability includes analyzing and reducing the collected data from traffic surveillance equipment and developing and implementing control plans for signalized intersections. Control plans may be developed and implemented that coordinate signals at many intersections under the domain of a single traffic management subsystem and are responsive to traffic conditions and adapt to support incidents, preemption and priority requests, pedestrian crossing calls, etc.
NYSDOT/NYCDOT/NYPD New York City Joint TMC TMC Multimodal Coordination This equipment package supports center-to-center coordination between the Traffic Management and Transit Management Subsystems. It monitors transit operations and provides traffic signal priority for transit vehicles on request from the Transit Management Subsystem.
NYSDOT/NYCDOT/NYPD New York City Joint TMC Roadway Signal Priority This equipment package includes the field elements that receive signal priority requests from transit vehicles approaching a signalized intersection. The request for priority may or may not be granted, based on the overall traffic situation at the intersection, adherence to the schedule of the transit vehicle, etc. If priority is granted, the operation of the traffic signal is adjusted to give an early green indication or hold a green indication that is already displaying
