Abstract
The present invention discloses a system which alerts vehicle drivers to avoid intersection vehicle collision, said system comprises of
- a plurality of vehicles containing a vehicle mount or portable collision avoidance device, the device having;
- a vehicle speed compare-tore CPU,
- a vehicle travel direction and vehicle location detection circuitry,
- a first and a secondary warning alarm circuitry, and
- an RF transceiver for receiving traffic signal light condition information from a broadcasting station which includes a traffic lights ID number, at least one traffic light condition signal at acquisition time.
The vehicle collision avoidance device generate a first warning alarm signal to warn the driver if the driver is not in compliance with the traffic light condition, if the driver becomes none responsive to the first warning alarm signal, the collision avoidance device transmits a secondary warring alarm signal(s) to other vehicle drivers the presence of an intersection vehicle collision condition.

4. - A system for avoiding intersection vehicle collision system, wherein said system comprises;
-
a plurality of vehicles containing a vehicle mount or portable vehicle collision avoidance device having; an RF transceiver designed for receiving traffic signal light condition information from a broadcasting station includes a traffic light ID number, at least one traffic light condition signal information at acquisition time, and said transceiver is designed to communicate with RF warning alarm signal(s) with other vehicle(s) located at the intersection, equipped with a collision avoidance device, a GPS receiver a processor and a first and second warning alarm generating circuitry, said GPS receiver map database containing location information of plurality of intersection having traffic signals, said vehicle collision avoidance devise GPS map processor in response to detecting a particular interaction located towards vehicle movement direction, and in response to received said particular intersection traffic signal light condition information, said vehicle collision avoidance device processor compares said particular intersection signal light condition received signal(s) information with said vehicle GPS location, said vehicle distance from said intersection and said vehicle movement direction with said vehicle speed, to determines if vehicle speed is in compliance based on said vehicle location and given intersection traffic signal light location, If said traffic signal light condition does not permit vehicle(s) to cross the intersection and the driver becomes not in compliance with said traffic signal light condition, said vehicle collision avoidance apparatus initiates said first warning alarm signal(s) to warn the driver to slow down to stop the vehicle at the intersection, if the driver becomes none responsive to said signal light condition, at a predetermined time said vehicle collision avoidance device generates a secondary RF warning alarm and establishes communication link with other vehicle(s) located with in the proximity of the intersection equipped with a collision avoidance device which upon receipt of said secondary transmitted signal, generates a warning alarm signal(s) to warn the other vehicle driver(s) to take necessary action to avoid intersection vehicle collision. - View Dependent Claims (6, 7, 9)
