National ITS Architecture Functional Requirements
associated with NWR Local Transit Centers:

Transit Center Priority Management

1. The center shall send requests for priority along routes or at intersections to traffic management.
2. The center shall analyze transit vehicle schedule performance to determine the need for priority along certain routes or at certain intersections.

Transit Center Information Services

1. The center shall enable yellow pages (including non-motorized transportation) information to be output to the traveler.
2. The center shall broadcast transit advisory data, including alerts and advisories pertaining to major emergencies, or man made disasters.
3. The center shall provide transit service information to traveler information service providers including routes, schedules, schedule adherence, and fare information as well as transit service information during evacuation.
4. The center shall exchange transit schedules, real-time arrival information, fare schedules, and general transit service information with other transit organizations to support transit traveler information systems.
5. The center shall provide transit information to the media including details of deviations from schedule of regular transit services.
6. The center shall provide travelers using public transportation with traffic and advisory information upon request. Such information may include transit routes, schedules, transfer options, fares, real-time schedule adherence, current incidents, weather conditions, and special events.

Transit Center Multi-Modal Coordination

1. The center shall coordinate schedules and services with traffic management, parking management, and event planning systems.
2. The center shall share transfer cluster and transfer point information with other transit centers. A transfer cluster is a collection of stop points, stations, or terminals where transfers can be made conveniently.
3. The center shall accept requests from traffic management to change routes and schedules as part of the implementation of demand management strategies.

Transit Evacuation Support

1. The center shall coordinate regional evacuation plans with Emergency Management - identifying the transit role in an evacuation and the transit resources that would be used.
2. The center shall manage the use of transit resources to support evacuation and subsequent reentry of a population in the vicinity of a disaster or other emergency.
3. The center shall coordinate the use of transit and school bus fleets during an evacuation, supporting evacuation of those with special needs and the general population.
4. The center shall adjust and update transit service and fare schedules and provide that information to other agencies as they coordinate evacuations.

Transit Center Paratransit Operations

1. The center shall process trip requests for demand responsive transit services, i.e. paratransit. Sources of the requests may include traveler information service providers.
2. The center shall disseminate up-to-date schedules and route information to other centers for demand responsive transit services (paratransit).
3. The center shall exchange information with Maintenance and Construction Operations concerning work zones, roadway conditions, asset restrictions, work plans, etc., that affect paratransit operations
4. The center shall monitor the operational status of the demand response vehicles including status of passenger pick-up and drop-off.
5. 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.

Transit Center Fixed-Route Operations

1. The center shall be able to generate special routes and schedules to support an incident, disaster, evacuation, or other emergency.
2. 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.
3. 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
4. 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.
5. The center shall exchange information with Maintenance and Construction Operations concerning work zones, roadway conditions, asset restrictions, work plans, etc.
6. The center shall disseminate up-to-date schedules and route information to other centers for fixed and flexible route services.

Transit Center Security

1. The center shall support the back-office portion of functionality to authenticate transit vehicle operators.
2. The center shall provide support to remotely disable (or reset the disabling of) a transit vehicle in service.
3. The center shall receive information pertaining to a wide-area alert such as weather alerts, disaster situations, or child abductions. This information may come from Emergency Management or from other Alerting and Advisory Systems.
4. The center shall monitor transit vehicle operational data to determine if the transit vehicle is off-route and assess whether a security incident is occurring.
5. The center shall receive reports of emergencies on-board transit vehicles entered directly be the transit vehicle operator or from a traveler through interfaces such as panic buttons or alarm switches.
6. The center shall send wide-area alert information to travelers (on-board transit vehicles or at stations/stops) and transit vehicle operators.

Transit Center Vehicle Tracking

1. The center shall provide transit operational data to traveler information service providers.
2. The center shall determine adherence of transit vehicles to their assigned schedule.
3. The center shall monitor the locations of all transit vehicles within its network.

Transit Center Data Collection

1. The center shall collect transit management data such as transit fares and passenger use, transit services, paratransit operations, transit vehicle maintenance data, etc.
2. The transit management center shall assign quality control metrics and meta-data to be stored along with the data. Meta-data may include attributes that describe the source and quality of the data and the conditions surrounding the collection of the data.
3. The center shall receive and respond to requests from ITS Archives for either a catalog of the transit data or for the data itself.
4. The transit management center shall be able to produce sample products of the data available.

Transit Garage Maintenance

1. The center shall assign technicians to a transit vehicle maintenance schedule, based upon such factors as personnel eligibility, work assignments, preferences and seniority.
2. The center shall verify that the transit vehicle maintenance activities were performed correctly, using the transit vehicle's status, the maintenance personnel's work assignment, and the transit maintenance schedules.
3. The center shall collect operational and maintenance data from transit vehicles.
4. The center shall monitor the condition of a transit vehicle to analyze brake, drive train, sensors, fuel, steering, tire, processor, communications equipment, and transit vehicle mileage to identify mileage based maintenance, out-of-specification or imminent failure conditions.
5. The center shall generate transit vehicle maintenance schedules that identify the maintenance or repair to be performed and when the work is to be done.
6. The center shall generate transit vehicle availability listings, current and forecast, to support transit vehicle assignment planning based, in part, on the transit vehicle maintenance schedule.
7. The center shall generate a time-stamped maintenance log of all maintenance activities performed on a transit vehicle.
8. The center shall provide transit operations personnel with the capability to update transit vehicle maintenance information and receive reports on all transit vehicle operations data.
