Transportation Information Center --> Shelter Provider Center:
emergency traveler information

Definitions

emergency traveler information (Information Flow): Public notification of an emergency such as a natural or man-made disaster, civil emergency, or child abduction. This flow also includes evacuation information including evacuation instructions, evacuation zones, recommended evacuation times, tailored evacuation routes and destinations, traffic and road conditions along the evacuation routes, traveler services and shelter information, and reentry times and instructions.

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.

Shelter Provider Center (Destination Physical Object): The 'Shelter Provider Center' provides information about the shelters that open with the threat of a disaster and are operated and maintained until the threat has passed. It may represent individual shelters if they have the capability to provide current information directly to ITS or it may represent a center operated by a managing organization such as the American Red Cross that operates the shelters and collects and provides aggregate shelter information for a region.

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

US: TMDD - NTCIP Messaging

Solution Description

This solution is used within Canada and the U.S.. It combines standards associated with US: TMDD with those for C-C: NTCIP Messaging. The US: TMDD standards include upper-layer standards required to implement center-to-center communications with traffic management systems. The C-C: NTCIP Messaging standards include lower-layer standards that support partially secure communications between two centers as commonly used in the US.

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 High Moderate
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. Incorrect information could lead to evacuation routes being taken that make the situation worse, rather than better, potentially leading to loss of life. It is better for the information to be unavailable than for it to be maliciously incorrect. MODERATE only because alternative mechanisms for receiving this data should be available. Could be HIGH if this is the only mechanism.
