PAT Vehicles

Status:

Existing

Definition:

Transit vehicles include ITS devices that support the safe and efficient movement of passengers. These systems collect, manage, and disseminate transit-related information to the driver, operations and maintenance personnel, and transit system patrons.

Stakeholder:

National ITS Architecture Functional Requirements
associated with PAT Vehicles:

Transit Vehicle On-Board Maintenance

1. The transit vehicle shall collect and process vehicle mileage data available to sensors on-board.
2. The transit vehicle shall collect and process the transit vehicle's operating conditions such as engine temperature, oil pressure, brake wear, internal lighting, environmental controls, etc.

Transit Vehicle Security

1. 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 storage (e.g., in an event recorder).
2. 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.
3. The transit vehicle shall output reported emergencies to the center.
4. 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.
5. 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.
6. 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.
7. 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 determine the schedule deviation and estimated times of arrival (ETA) at transit stops.

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 include a database on-board the transit vehicle for use in fare processing from which the fares for all possible trips within the transit operational network can be determined.
3. The transit vehicle shall support the support advanced payments for tolls, and/or parking lot charges, and/or transit fares via the traveler card / payment instrument.
4. The transit vehicle shall provide fare statistics data to the center.
5. The transit vehicle shall read data from the traveler card / payment instrument presented by boarding passengers.

Transit Vehicle On-Board Trip Monitoring

1. The transit vehicle shall record transit trip monitoring data including operational status information such as doors open/closed, running times, etc.
2. The transit vehicle shall record transit trip monitoring data including vehicle mileage and fuel usage.
3. The transit vehicle shall track the current location of the transit vehicle.

Transit Vehicle On-Board Paratransit Operations

1. The transit vehicle shall provide the capability to log passenger boardings and alightings and make passenger use data available to the transit center.
2. The transit vehicle shall receive the status of demand responsive or flexible-route transit schedules and passenger loading from the transit vehicle operator.
3. The transit vehicle shall provide the transit vehicle operator instructions about the demand responsive or flexible-route transit schedule that has been confirmed from the center.
