Patent ID: 7650236

Claim:
A system to reduce the possibility of a vehicle entering a freeway ramp in the wrong direction of travel, towards oncoming traffic, and comprised of a navigation receiver, computer, electromechanical controls, comprising: a satellite receiver, with or without bidirectional communications capability, housed in a motor vehicle with global positioning capabilities to compute, display and annunciate, its longitude, latitude and direction of travel in conjunction with a mirror being positioned in proximity to a freeway access ramp so positioned as to reflect an oncoming vehicle, and its headlights, such that the vehicle's driver sees his vehicle as an oncoming vehicle, stops, and reverses his direction of travel thereby avoiding collision; further comprising an electromechanical or solid state controller to nondestructively disable a vehicle ignition system when a satellite receiver computes and detects that the receiver's and therefore vehicle's, location and direction of travel is such that the vehicle is entering, or about to enter, a freeway ramp in the wrong direction of travel.
