Transportation Information Center --> Light Vehicle OBE:
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.
Light Vehicle OBE (Destination Physical Object): The 'Light Vehicle OBE' includes traveler-oriented capabilities that apply to passenger cars, trucks, and motorcycles that are used for personal travel. The rules vary by jurisdiction, but generally light vehicles are restricted in their weight and the maximum number of passengers they can carry. In ARC-IT, the Light Vehicle OBE represents vehicles that are operated as personal vehicles that are not part of a vehicle fleet and are not used commercially; thus, the choice between the various vehicle subsystems should be based more on how the vehicle is used than how much the vehicle weighs. See also the 'Vehicle' subsystem that includes the general safety and information services that apply to all types of vehicles, including light vehicles.

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. | Emergency-related data needs to be correct or safety-affecting decisions may have severe negative consequences. | MODERATE only because alternative mechanisms for receiving this data should be available. Could be HIGH if this is the only mechanism. |
