Personal Information Device --> Transit Management Center:
trip confirmation

Definitions

trip confirmation (Information Flow): Acknowledgement by the driver/traveler of acceptance of a trip plan with associated personal and payment information required to confirm reservations. Conversely, this flow may also reject the proposed trip plan. Confirmations include the selected route and subsequent trip confirmation messages will be issued for route changes.

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.

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) - Apache Kafka over Wireless

Solution Description

This solution is used within the U.S.. It combines standards associated with (None-Data) with those for Apache Kafka over Wireless. The (None-Data) standards include an unspecified set of standards at the upper layers. The Apache Kafka over Wireless standards include lower-layer open source code that supports data distribution of specific types of data over wireless links.

Basis This is predictive of traveler location and intent. A third party with hostile intent toward the traveler could use this information against the traveler. If this data is corrupted, the transit management center may not understand the traveler's intent and not properly serve the traveler. This acknowledgement is part of the real-time feedback for on-demand travel services. If this doesn't work, the on-demand service doesn't work.
