A demonstration project for the ITS data bus prototype

A variety of information sources are finding their way into road vehicles, helping to bridge the gap between the highway and the driver. These devices can provide information on route guidance, safety and hazard alerts, and traffic congestion advisories in real time. The devices and the information they provide should be tailored to driver needs, the traffic and environmental conditions and other situation parameters affecting the driver's travel. Safe installation and operation are a function of the extent to which devices can be easily installed and obtain vehicle information required for device functioning, while not corrupting existing vehicle data and functions. A dual-bus architecture has been designed as the basis for a family of Society of Automotive Engineers (SAE) standards, in which an ITS Data Bus (TDB) is connected to the vehicle multiplex bus through a gateway. When implemented, this architecture permits electronic device manufacturers to build a single automotive version of their product which can plug into the IDB in any vehicle.
