Intersection vehicle collision avoidance system
First Claim
1. - A method for avoiding intersection vehicle collision, said system comprising of;
- Intersection traffic signal(s) condition transmitter(s) and or a transceiver(s). A Vehicle mount speed compare-tore CPU, with a receiver and or a transceiver. A Vehicle travel direction detection database processor circuitry. And a vehicle warning alarm circuitry. Said intersection traffic signal transmitter(s) and or transceivers(s) at a pre-set time transmitting unique coded signal containing information to each One of said particular traffic direction signal condition. A plurality of vehicle traveling towards said intersection, equipped with vehicle speed compare-tore CPU, said vehicle speed comparator CPU receiving said uniquely coded traffic Signal condition signal(s). When a particular direction travel vehicle(s) comparator CPU, Received particular direction intersection traffic signal condition code (ember, Red signal light, or stop sign or speed limit sign) match with said vehicle travel direction detection processor read code. At a predetermine vehicle distance from said intersection, said vehicle speed comparator processor clock compares said vehicle speed said vehicle speed compare-tore CPU determines said vehicle speed being in compliance based on said vehicles location distance from said traffic signal(s). If said vehicle speed compare-tore processor reading indicates said vehicle speed is not in compliances with said traffic signal condition, said vehicle speed compare-tore CPU will initiate warning alarm signal(s)

Abstract
The present invention discloses a system that alerts to the operator of a vehicle, when a particular vehicle operator is not in the course of slowing down to stop a vehicle traveling towards an intersection, in particularly when said vehicle moving direction intersection traffic light condition turns ember and or red. Or where an intersection requires all or particular direction travel vehicles to make a full stop before said vehicles cross said intersection, to avoid intersection vehicle collision. The system comprises of traffic light or stop sign RF transceivers units, and plurality of vehicles equipped with vehicle transceivers units to communicate with said intersection traffic signal transceiver units. And said vehicle transceiver unit is equipped with vehicle speed sensors comparator CPU and vehicle movement direction detecting sensor circuitry, using transponder reader, compass or GPS receiver to detect vehicle direction movement, and to detect signal light condition along with monitoring vehicle speed. If a vehicle operator after receiving said warning signals at a predetermined time does not maintain vehicle speed in compliances with said traffic signal light condition, the vehicle mount speed comparator CPU will alert the pedestrians, other vehicle operators located within said particular intersection with an audio-visual or vibrating alarm signals. And upon said vehicle passing said intersection wile said traffic direction signal condition indicating an stop condition, said vehicle speed comparator CPU transmits said violation signal to a monitoring station with information containing to the particular vehicle and it'"'"'s operator. Said monitoring station is equipped with a computer database connected to an Internet or intranet.

17. - A method for avoiding intersection vehicle collision system, wherein plurality of vehicles equipped with GPS receiver connected to a vehicle speed comparator CPU. And to a warning alarm generating circuitry. Said GPS unit database containing location information of plurality of intersection traffic signals and or traffic location speed limit information of a wide area. Wherein said particular vehicle(s) traveling towards an interaction, said intersection location information is within said vehicle GPS unit mapping. At preset vehicle distance location detection from said intersection, said vehicle GPS unit transmits signal(s) to said vehicle speed comparator CPU containing information to said vehicle speed, location, and vehicle travel direction code. If vehicle speed is in compliance with given vehicle location, the vehicle speed comparator will not produce alarm signal(s) if vehicle is not in compliance said vehicle speed compare-tore CPU will initiate warning collision alarm signal(s)
