Functional Areas

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.

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.

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.

Transit Center Fixed-Route Operations

• The center shall generate transit routes and schedules based on such factors as parameters input by the system operator, road network conditions, incident information, operational data on current routes and schedules, and digitized map data.
• 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 initiate these processes
• The center shall be able to generate special routes and schedules to support an incident, disaster, evacuation, or other emergency.
• The center shall dispatch fixed route or flexible route transit vehicles
• The center shall collect transit operational data for use in the generation of routes and schedules.
• The center shall provide instructions or corrective actions to the transit vehicle operators based upon operational needs.
• The center shall manage large deviations of individual transit vehicles, deviations in rural areas, and deviations of large numbers of vehicles.
• 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 termination of some services, etc.
• The center shall exchange information with Maintenance and Construction Operations concerning work zones, roadway conditions, asset restrictions, work plans, etc.
• The center shall disseminate up-to-date schedules and route information to other centers for fixed and flexible route services.

Transit Center Paratransit Operations

• The center shall process trip requests for demand responsive transit services, i.e. paratransit. Sources of the requests may include traveler information service providers.
• The center shall monitor the operational status of the demand response vehicles including status of passenger pick-up and drop-off.
• The center shall generate demand response transit (including paratransit) routes and schedules based on such factors as parameters input by the system operator, what other demand responsive transit schedules have been planned, the availability and location of vehicles, the relevance of any fixed transit routes and schedules, road network information, and incident information.
• The center shall dispatch demand response (paratransit) transit vehicles.
• The center shall exchange information with Maintenance and Construction Operations concerning work zones, roadway conditions, asset restrictions, work plans, etc.
• The center shall disseminate up-to-date schedules and route information to other centers for demand responsive transit services (paratransit).

Transit Center Vehicle Tracking

• The center shall monitor the locations of all transit vehicles within its network.
• The center shall determine adherence of transit vehicles to their assigned schedule.
• The center shall support an interface with a map update provider, or other appropriate data sources, through which updates of digitized map data can be obtained and used as a background for transit tracking and dispatch.
• The center shall provide transit operational data to traveler information service providers.

Transit Vehicle Operator Assignment

• The center shall maintain records of a transit vehicle operator's performance. This may be done utilizing standardized performance evaluation criteria set forth by governmental regulations and transit operating company policies, assessing the transit vehicle operator's driving history, and assessing comments from the transit vehicle operator's supervisor(s) as well as noting any moving violations or accidents, supervisor comments, government regulations, and company policies.
• The center shall assess the transit vehicle operator's availability based on previous work assignments, accumulated hours, plus health and vacation commitments.
• The center shall assign transit vehicle operators to transit schedules based on their eligibility, route preferences, seniority, and transit vehicle availability.
• The center shall provide an interface through which the transit vehicle operator information can be maintained - either from the transit vehicle operator, center personnel, or other functions.
