| Functional Area: On-board Schedule Management |
- 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.
- The transit vehicle shall use the route information and its current location to determine the deviation from the predetermined schedule.
- The transit vehicle shall calculate the estimated times of arrival (ETA) at transit stops.
- The transit vehicle shall determine scenarios to correct the schedule deviation.
- 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.
- The transit vehicle shall send the schedule deviation and estimated arrival time information to the center.
- 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.
- 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.

| Functional Area: On-board Maintenance |
- The transit vehicle shall collect and process vehicle mileage data available to sensors on-board.
- 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.
- The transit vehicle shall transmit vehicle maintenance data to the center to be used for scheduling future vehicle maintenance.
|
| Functional Area: On-board Paratransit Operations |
- The transit vehicle shall manage data input to sensor(s) on-board a transit vehicle to determine the vehicle's availability for use in demand responsive and flexible-route transit services based on identity, type, and passenger capacity.
- The transit vehicle shall receive the status of demand responsive or flexible-route transit schedules and passenger loading from the transit vehicle operator.
- 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.
- The transit vehicle shall provide the capability to log passenger boardings and alightings and make passenger use data available to the transit center.
|
| Functional Area: On-board Transit Trip Monitoring |
- The transit vehicle shall track the current location of the transit vehicle.
- 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 recording trip length.
- The transit vehicle shall record transit trip monitoring data including vehicle mileage and fuel usage.
- 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 send the transit vehicle trip monitoring data to center-based trip monitoring functions.
