Transit Management Center --> Personal Information Device:
transfer status

Definitions

transfer status (Information Flow): Information indicating whether a requested transfer can be confirmed including specific information about the connection including fare payment information. Real-time updates are provided if the transfer status changes up to and including a reminder just prior to the transfer. In the event that a requested transfer is not feasible, alternatives including other transit, rideshare, and taxi options are provided.

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.

Personal Information Device (Destination 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.

Communication Solutions

Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

(None-Data) - OMG DDS over Wireless

Solution Description

This solution is used within the U.S.. It combines standards associated with (None-Data) with those for OMG DDS over Wireless. The (None-Data) standards include an unspecified set of standards at the upper layers. The OMG DDS over Wireless standards include lower-layer standards that support secure data sharing and command operations between remote devices over wireless links.

Basis Contains a personalized reponse to an individual traveler, so should not be readable by anyone except that traveler. If incorrect, the traveler may believe they have to make other plans, which is a significant inconvenience to them, but affects a limited scope so MODERATE not HIGH. If unavailable, the traveler may make other plans, which is a significant inconvenience to them, but affects a limited scope so MODERATE not HIGH.
