A number of dynamic in-vehicle navigation and route guidance system architectures are described and their properties classified. Five typical architectures for exogenous systems, and three endogenous system architectures are described. The functional capability and design complexity of exogenous systems are shown to vary over a wide range. These systems depend on basic external information sources which define the physical network over which the system operates. They require only one-way communication using existing channels and media. Endogenous systems do not have an externally defined network limitation. The infrastructure or bandwidth requirements are usually extensive and this, along with the requirements for common data formats and transmission standards, implies extensive government participation. A minimum number of vehicles is required on the network for effective operation.
