1. A system for communicating traffic information to a mobile user, comprising:
- a traffic information station for aggregating and transmitting aggregated traffic information of segments of a road network;
an uplink communicator for transmitting said aggregated traffic information;
at least one satellite for receiving said aggregated traffic information from said uplink communicator and transmitting the received aggregated traffic information;
a receiver for receiving said transmitted aggregated traffic information from said at least one satellite; and
a navigation system for receiving said transmitted aggregated traffic information, processing said traffic information and delivering to a driver interface to permit said mobile user to receive the navigation system for reporting traffic congestion information at said segments of said road network.

Abstract
A method and system for collecting and distributing vehicle traffic congestion information is disclosed. The method and system optionally involves deploying probe vehicles or other data sources for collecting and transmitting detailed traffic information which describes vehicle speeds actually being experienced along the routes of interest and transmitting all this information into a central computer at a central traffic data station, where the data are processed.
