Functional Areas

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.

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 Multi-Modal Coordination

• The center shall coordinate schedules and services between transit agencies, traffic management, maintenance and construction operations, parking management, and other surface or air transportation modes.
• The center shall share transfer cluster and transfer point information with multimodal transportation service providers, other transit agencies, and traveler information service providers. A transfer cluster is a collection of stop points, stations, or terminals where transfers can be made conveniently.
• The center shall accept requests from traffic management to change routes and schedules as part of the implementation of demand management strategies.
