Transportation Information Center --> Other Transportation Information Centers:
incident information for public

This triple is bi-directional. See also Other Transportation Information Centers --> Transportation Information Center: incident information for public

Definitions

incident information for public (Information Flow): Report of current desensitized incident information prepared for public dissemination.

Transportation Information Center (Source 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.

Other Transportation Information Centers (Destination 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.

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

EU: DATEX - DATEX Messaging

Solution Description

This solution is used within the E.U.. It combines standards associated with EU: DATEX with those for C-C: DATEX Messaging. The EU: DATEX standards include upper-layer standards required to exchange and share data and information in the field of traffic and travel. The C-C: DATEX Messaging standards include lower-layer standards that support partially secure communications between two centers as commonly used in Europe.

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 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. Publicly shared data about planned incidents should be accurate and delivered in timely fashion so as to enable end users to react appropriately; otherwise, signficant mobility challenges may result.
