Other Transit Management Centers --> Transit Management Center:
transit service coordination

This triple is bi-directional. See also Transit Management Center --> Other Transit Management Centers: transit service coordination

Definitions

transit service coordination (Information Flow): Schedule coordination or AVL information shared between local/regional transit organizations. This includes coordination of connections and control parameters between transit properties as well as coordination of transit-related maintenance activities.

Other Transit Management Centers (Source Physical Object): Representing another transit operations center, 'Other Transit Management Centers' is intended to provide a source and destination for information flows between peer transit management centers. It enables transit management activities to be coordinated across geographic boundaries or jurisdictions.

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) - Secure Internet (ITS)

Solution Description

This solution is used within Australia, Canada, the E.U. and the U.S.. It combines standards associated with (None-Data) with those for I-I: Secure Internet (ITS). The (None-Data) standards include an unspecified set of standards at the upper layers. The I-I: Secure Internet (ITS) standards include lower-layer standards that support secure communications between ITS equipment using X.509 or IEEE 1609.2 security certificates.

Note that some layers might have alternatives, in which case all of the gap icons associated with every alternative may be shown on the diagram, but the solution severity calculations (and resulting ordering of solutions) includes only the issues associated with the default (i.e., best, least severe) alternative.

Interoperability Description
Regional Interoperability throughout the geopolitical region is highly desirable, but if implemented differently in different transportation management jurisdictions, significant benefits will still accrue in each jurisdiction. Regardless, this Information Flow Triple should be implemented consistently within a transportation jurisdiction (i.e., the scope of a regional architecture).

Basis Coordination between transit systems is generally not sensitive, however this flow may include information related to serving individual connection protection requests that are sensitive. If this information is not timely or correct, transit agencies may not properly coordinate, leaving some users unserved. If this information is not timely or correct, transit agencies may not properly coordinate, leaving some users unserved.
