Project Functional Requirements (Element - Functional Object):

Indianapolis DPW Operations 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.

Indianapolis DPW Roadside 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.
6: The field element shall return traffic signal controller operational status to the center.
8: The field element shall report current transit priority status to the center.

IndyGo Operations Center - Transit Center Priority Management

1: The center shall analyze transit vehicle schedule performance to determine the need for priority along certain routes or at certain intersections.

IndyGo 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.
4: The transit vehicle shall prevent a priority request from being sent when the transit vehicle cannot use the priority (e.g., when the transit vehicle makes a passenger stop on the approach to an intersection).
