• The transit vehicle shall monitor and output surveillance and sensor equipment status and fault indications.
• The transit vehicle shall output an indication of potential incidents or threats and the processed sensor information to the center along with the vehicle’s current location.
• The transit vehicle shall output an indication of potential incidents or threats and the processed video or audio information to the center along with the vehicle’s current location.
• The transit vehicle shall output reported emergencies to the center.
• The transit vehicle shall perform authentication of the transit vehicle operator.
• 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.
• The transit vehicle shall perform video and audio surveillance inside of transit vehicles and output raw video or audio data for either local monitoring (for processing or direct output to the transit vehicle operator), remote monitoring or for local stor
• 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.

On-board Transit Signal Priority

• The transit vehicle shall determine the schedule deviation and estimated times of arrival (ETA) at transit stops.
• 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).
• 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 devia
• The transit vehicle shall send the schedule deviation data and status of priority requests to the transit vehicle operator and provide the capability for the transit vehicle operator to control the priority system.

On-board Transit Trip Monitoring

• The transit vehicle shall record transit trip monitoring data including operational status information such as doors open/closed, running times, etc.
• The transit vehicle shall record transit trip monitoring data including vehicle mileage and fuel usage.
• The transit vehicle shall send the transit vehicle trip monitoring data to center-based trip monitoring functions.
• The transit vehicle shall support the computation of the location of a transit vehicle using on-board sensors to augment the location determination function. This may include proximity to the transit stops or other known reference points as well as recor
• The transit vehicle shall track the current location of the transit vehicle.

Roadway Signal Priority

• The field element shall respond to requests for indicator (e.g., signal) priority requests from transit vehicles at intersections, pedestrian crossings, and multimodal crossings.

Transit Center Fixed-Route Operations

• The center shall be able to generate special routes and schedules to support an incident, disaster, evacuation, or other emergency.
• The center shall collect transit operational data for use in the generation of routes and schedules.
• The center shall dispatch fixed route or flexible route transit vehicles
• The center shall disseminate up-to-date schedules and route information to other centers for fixed and flexible route services.
• The center shall exchange information with Maintenance and Construction Operations concerning work zones, roadway conditions, asset restrictions, work plans, etc.
• The center shall generate the necessary corrective actions which may involve more than the vehicles concerned and more far reaching action, such as, the introduction of extra vehicles, wide area signal priority by traffic management, the premature termina
• The center shall manage large deviations of individual transit vehicles, deviations in rural areas, and deviations of large numbers of vehicles.
• The center shall provide an interface to the archive data repository to enable the operator to retrieve historical operating data for use in planning transit routes and schedules.
• The center shall provide instructions or corrective actions to the transit vehicle operators based upon operational needs.
• The center shall provide the interface to the system operator to control the generation of new routes and schedules (transit services) including the ability to review and update the parameters used by the routes and schedules generation processes and to i

Transit Center Passenger Counting

• The center shall calculate transit ridership data by route, route segment, transit stop, time of day, and day of week based on the collected passenger count information.
• The center shall collect passenger count information from each transit vehicle.
• The center shall make the compiled ridership data available to the system operator and other applications.

Transit Center Security
