Transportation Information Center --> Light Vehicle OBE:
guidance updates

Definitions

guidance updates (Information Flow): Information provided to support route guidance that is responsive to current traffic and road conditions. This includes measures of link impedances/delays that can impact routing choices and routing alternatives.

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.
