Personal Information Device --> Transit Management Center:
transit stop request
Definitions
transit stop request (Information Flow): Notification that a transit stop has been requested by a transit user at a roadside stop. This flow identifies the route, stop, and the time of the request.
Personal Information Device (Source Physical Object): The 'Personal Information Device' provides the capability for travelers to receive formatted traveler information wherever they are. Capabilities include traveler information, trip planning, and route guidance. Frequently a smart phone, the Personal Information Device provides travelers with the capability to receive route planning and other personally focused transportation services from the infrastructure in the field, at home, at work, or while en-route. Personal Information Devices may operate independently or may be linked with vehicle on-board equipment. This subsystem also supports safety related services with the capability to broadcast safety messages and initiate a distress signal or request for help.
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.

Rating | High | Moderate | Moderate | |
Basis | Contains PII, including traveler identity, location and stop request information, which is predictive of traveler location. | If corrupted, stop request may not be received or acted upon, which would affect the originator of the request. Limited in scope to that request though. | If this flow is not available then stop requests won't be completed and the originator of the request is inconvenienced. Long term however, if this flow is generally not reliable then users are unlikely to use or rely on it. Should be MODERATE to instill confidence and encourage use. |
