Traveler Support Equipment --> Transit Management Center:
transit information user request
Definitions
transit information user request (Information Flow): Request for special transit routing, real-time schedule information, and availability information.
Traveler Support Equipment (Source Physical Object): 'Traveler Support Equipment' provides access to traveler information at transit stations, transit stops, other fixed sites along travel routes (e.g., rest stops, merchant locations), and major trip generation locations such as special event centers, hotels, office complexes, amusement parks, and theaters. Traveler information access points include kiosks and informational displays supporting varied levels of interaction and information access. At transit stops this might be simple displays providing schedule information and imminent arrival signals. This may be extended to include multi-modal information including traffic conditions and transit schedules to support mode and route selection at major trip generation sites. Personalized route planning and route guidance information can also be provided based on criteria supplied by the traveler. It also supports service enrollment and electronic payment of transit fares. In addition to the traveler information provision, it also enhances security in public areas by supporting traveler activated silent alarms.
Transit Management Center (Destination Physical Object): The 'Transit Management Center' manages transit vehicle fleets and coordinates with other modes and transportation services. It provides operations, maintenance, customer information, planning and management functions for the transit property. It spans distinct central dispatch and garage management systems and supports the spectrum of fixed route, flexible route, paratransit services, transit rail, and bus rapid transit (BRT) service. The physical object's interfaces support communication between transit departments and with other operating entities such as emergency response services and traffic management systems.

Interoperability | Description |
---|---|
Local | In cases where an interface is normally encapsulated by a single stakeholder, interoperability is still desirable, but the motive is vendor independence and the efficiencies and choices that an open standards-based interface provides. |

Basis | Contains a personalized request by an individual traveler, so should not be readable by anyone except the intended recipient. | If corrupted this would result in failed connection protection. If modified intentionally would cause either failed protection or unnecessary protection. In any case these affect the efficacy and efficiency of the transit system, but the scope of the effects are limited, thus MODERATE and not HIGH. | If unavailable that transit connection protection will not function. Given the scope of the application, this affects only those riders requiring protection, which should be limited scope, thus MODERATE and not HIGH. |
