Transit Management Center --> Traveler Support Equipment:
alarm acknowledge
Definitions
alarm acknowledge (Information Flow): Confirmation that alarm was received, instructions and additional information for the alarm initiator, and requests for additional information.
Transit Management Center (Source 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.
Traveler Support Equipment (Destination 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.

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 | While this flow may not directly include PII, it responds to one that does. Security requirements for response flows set at minimum to those of the triggering flow. | Even a minor discrepancy in this data could have a significant effect for a personal safety incident. | Data describing incidents on board a transit vehicle, station or other public transport facility likely to include one or more travelers must be timely or appropriate measures may be delayed, which could impact personal safety. Could be HIGH. |
