Accident avoidance system using an infrastructure system to convey location information between vehicles includes at least two vehicles approaching or traveling on a roadway and each having onboard, a position determining system onboard that receives satellite positioning signals from a plurality of satellites and determines location information based on the satellite positioning signals, a transmitter that transmits the location information for the vehicle to an infrastructure system, a receiver that receives location information for another vehicle from the infrastructure system, and an accident risk warning system that alerts its operator of a risk of an accident based on the location information for any other vehicles and map data representing the roadway including edges or lane boundaries of the roadway.

The invention claimed is: 1. An accident avoidance system using an infrastructure system to convey location information between vehicles, comprising:a first vehicle approaching or traveling on a roadway comprising:a position determining system onboard the first vehicle that receives satellite positioning signals from a plurality of satellites and determines location information for the first vehicle based on the satellite positioning signals,a transmitter onboard the first vehicle that transmits the location information for the first vehicle to the infrastructure system,a receiver onboard the first vehicle that receives location information for a second vehicle from the infrastructure system, andan accident risk warning system onboard the first vehicle that alerts an operator of the first vehicle of a risk of an accident involving the first vehicle based on the location information for the first vehicle and map data representing the roadway including edges or lane boundaries of the roadway; andthe second vehicle comprising:a position determining system onboard the second vehicle that receives satellite positioning signals from the plurality of satellites and determines a location of the second vehicle based on the satellite positioning signals,a transmitter onboard the second vehicle that transmits the location information for the second vehicle to the infrastructure system,a receiver onboard the second vehicle that receives the location information for the first vehicle from the infrastructure system, andan accident risk warning system onboard the second vehicle that alerts an operator of the second vehicle of a risk of an accident involving the second vehicle based on the location of the second vehicle and the map data representing the roadway including the edges or lane boundaries of the roadway.
