National ITS Architecture Functional Requirements
associated with HRT Transit Vehicles:

Transit Vehicle Signal Priority

1. The transit vehicle shall determine the schedule deviation and estimated times of arrival (ETA) at transit stops.
2. 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.
3. 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 Passenger Counting

1. The passenger counts shall be timestamped so that ridership can be measured by time of day and day of week.
2. The transit vehicle shall send the collected passenger count information to the transit center.
3. The passenger counts shall be related to location to support association of passenger counts with routes, route segments, or bus stops.
4. The transit vehicle shall count passengers boarding and alighting.

Transit Vehicle Schedule Management

1. The transit vehicle shall provide the schedule deviations and instructions for schedule corrections to the transit vehicle operator if the deviation is small, or the transit vehicle is operating in an urban area.
2. The transit vehicle shall support the operations of a flexible route service. This may include requests for route deviations that would then lead to schedule corrective actions.
3. The transit vehicle shall send the schedule deviation and estimated arrival time information to the center.
4. The transit vehicle shall determine scenarios to correct the schedule deviation.
5. The transit vehicle shall calculate the estimated times of arrival (ETA) at transit stops.
6. The transit vehicle shall use the route information and its current location to determine the deviation from the predetermined schedule.
7. 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.
8. The transit vehicle shall notify the transit center of vehicle location and operational status as the vehicle exits and returns to the transit facility to support future vehicle assignments.

Transit Vehicle On-Board Fare Management

1. The transit vehicle shall calculate the traveler's fare based on the origin and destination provided by the traveler as well as factors such as the transit routing, transit fare category, traveler history, and route-specific information.
2. The transit vehicle shall have access to the complete range of transit services (routes and schedules) that are available to the traveler.
3. The transit vehicle shall provide a transit fare payment interface that is suitable for travelers with physical disabilities.
4. 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.
5. 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.
6. The transit vehicle shall provide fare statistics data to the center.
7. The transit vehicle shall provide an image of all travelers which shall be used for violation processing of those who do not have a traveler card / payment instrument or whose transit fare transaction fails.
8. 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 send the transit vehicle trip monitoring data to center-based trip monitoring functions.
4. 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.
