Definitions

transit traveler information coordination (Information Flow): Transit schedules, real-time arrival information, fare schedules, and general transit service information shared between transit organizations to support transit traveler information systems.

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.

Other Transit Management Centers (Destination 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.

US: TCIP - Secure Internet (ITS) (18)
(None-Data) - Secure Internet (ITS) (43)

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).

Security

Information Flow Security
	Confidentiality	Integrity	Availability
Rating	Low	Moderate	Moderate
Basis	Does not contain any personal or confidential information.	While accuracy of this data is important for decision making purposes, the greatest impact if manipulated or incorrect data would be financial and likely limited in scope. For example, making all options appear less expensive than an attacker's route of fiduciary interest, driving revenue to his route. This is undesireable and significant, but not catastrophic. Thus MODERATE generally.	While accuracy of this data is important for decision making purposes, applications should be able to function without frequent updates. Thus MODERATE generally.
