The In-Vehicle Traffic Congestion Information System (ICI system) consists of a technique to provide real-time traffic congestion data to drivers of suitably equipped vehicles. The ICI system includes apparatus for gathering and formatting data at a central location, transmitting the data to vehicles, processing data in the vehicles and presenting it to the drivers. The ICI system design provides inputs for a wide range of data sources at a central location where, through a data fusion process, information from a range of sources may be accumulated and aggregated into a single congestion level data value for each section of road. In the vehicles, a range of options may be available for presenting relevant congestion data to the driver including text, voice and map displays.
