Definitions

transit service information (Information Flow): Transit service information including routes, schedules, and fare information as well as dynamic transit schedule adherence and transit vehicle location information.

Other Transportation Information Centers (Source Physical Object): Representing another Transportation Information Center, this object is intended to provide a source and destination for ITS information flows between peer information and service provider functions. It enables cooperative information sharing between providers as conditions warrant.

Transportation Information Center (Destination Physical Object): The 'Transportation Information Center' collects, processes, stores, and disseminates transportation information to system operators and the traveling public. The physical object can play several different roles in an integrated ITS. In one role, the TIC provides a data collection, fusing, and repackaging function, collecting information from transportation system operators and redistributing this information to other system operators in the region and other TICs. In this information redistribution role, the TIC provides a bridge between the various transportation systems that produce the information and the other TICs and their subscribers that use the information. The second role of a TIC is focused on delivery of traveler information to subscribers and the public at large. Information provided includes basic advisories, traffic and road conditions, transit schedule information, yellow pages information, ride matching information, and parking information. The TIC is commonly implemented as a website or a web-based application service, but it represents any traveler information distribution service.

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) - OASIS AMQP

Solution Description

This solution is used within Canada, the E.U. and the U.S.. It combines standards associated with (None-Data) with those for OASIS AMQP. The (None-Data) standards include an unspecified set of standards at the upper layers. The OASIS AMQP standards include lower-layer standards that support data distribution of specific types of data.

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	Low
Basis	Generally, center-originating flows destined for a TIC don't contain any personal or confidential information, and are eventually intended for some kind of public consumption.	Generally transportation coordination information should be correct between source and destination, or inappropriate actions may be taken.	While useful, there is no signficant impact if this flow is not available.
