National ITS Architecture Functional Requirements
associated with WMATA Transit Vehicles:

Transit Vehicle Security

1. The transit vehicle shall perform local monitoring of video or audio surveillance data collected inside of transit vehicles, and identify potential incidents or threats based on received processing parameters.
2. The transit vehicle shall output reported emergencies to the center.
3. 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.
4. The transit vehicle shall receive acknowledgments of the emergency request from the center and output this acknowledgment to the transit vehicle operator or to the travelers.
5. 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.

Transit Vehicle On-Board Fare Management

1. The transit vehicle shall provide a transit fare payment interface that is suitable for travelers with physical disabilities.
2. The transit vehicle shall provide fare statistics data to the center.
3. The transit vehicle shall read data from the traveler card / payment instrument presented by boarding passengers.
4. The transit vehicle shall support an emergency fare structure overriding all other fares that can be activated during disasters, states of emergency or evacuations.
