Abstract
A road information communicating system is provided in which a central communication system communicates with vehicles using a network of distributed information processing units. Each of these distributed information processing units is able to receive local road information and compute a set of local coordinates corresponding to that local road information. It is then able to relay that information to the central unit and receive like information from other distributed units. The information is then prioritized, and a subset of that prioritized data is selected and transmitted to vehicles in the coverage area.
