ABSTRACT:
A system for sharing and processing traffic information includes a number of traffic information computer systems within individual vehicles and a traffic information server system. The traffic information computer systems are each connected to the server system through a network, which are additionally connected to one another by peer-to-peer radio communications, and which each operate with a database for displaying road maps, with a database storing average speed data for directions of travel along roadways, and with a location sensor used to determine the location and average speed of the vehicle, which are transmitted to the server. The server returns average speed data for road segments, which is displayed on the road maps.
