Accident avoidance system for a host vehicle includes a global positioning
system residing on the host vehicle for determining the host vehicle's
location as the host vehicle travels based on signals received from one
or more satellites, a map database having digital maps corresponding to
an area including the location of the host vehicle as determined by the
global positioning system, a vehicle-to-vehicle communication system
residing on the host vehicle operative for receiving signals including
location information acquired by global positioning systems residing on
other vehicles directly from the other vehicles indicating the locations
of the other vehicles, and a navigation system including a display
residing on the host vehicle for displaying images to an occupant of the
host vehicle showing the digital maps and indications of the locations of
the host vehicle and the other vehicles on the digital maps. The
