National ITS Architecture Functional Requirements
associated with NRO Local Transit Vehicles:

Transit Vehicle Security

1. The transit vehicle shall accept emergency inputs from either the transit vehicle operator or a traveler through such interfaces as panic buttons, silent or audible alarms, etc.
2. The transit vehicle shall be capable of receiving an emergency message for broadcast to the travelers or to the transit vehicle operator.

Transit Vehicle Signal Priority

1. 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.

Transit Vehicle Schedule Management

1. The transit vehicle shall receive a vehicle assignment including transit route information, transit service instructions, traffic information, road conditions, and other information for the operator.
