What is claimed is: 1. A system for preventing traffic signal violation using infrared communication, the system comprising: a traffic light controlling system for, when a traffic light changes, transmitting traffic information; a brake system for decelerating or stopping a vehicle under a predeter
What is claimed is: 1. A system for preventing traffic signal violation using infrared communication, the system comprising: a traffic light controlling system for, when a traffic light changes, transmitting traffic information; a brake system for decelerating or stopping a vehicle under a predetermined control; and a traffic signal violation prevention device installed at the vehicle, and receiving the traffic information and, if the traffic information is stop signal information, transmitting a stop signal to the brake system, wherein the traffic signal violation prevention device has a distance measurement unit for measuring a distance from another vehicle positioned in rear of the vehicle and, when the measured distance from another vehicle is greater than a predetermined distance, transmits the stop signal to the brake system. 2. The system according to claim 1, wherein the traffic light controlling system comprises: a timer for counting a time; a traffic light having a plurality of lights representing whether or not to run the vehicle, and turning on/off under a predetermined control; a controller for controlling sequential lighting of the traffic lights depending on the counted time and, when the lighted light changes, generating the traffic information; and an infrared transmitter for loading and transmitting the traffic information on an infrared frequency. 3. The system according to claim 1, wherein the traffic signal violation prevention device detects a speed of the vehicle and, when the detected speed is less than a previously set speed, transmits the stop signal to the brake system. 4. The system according to claim 3, wherein the traffic signal violation prevention device has a distance measurement unit for measuring a distance from another vehicle positioned in rear of the vehicle and, when the measured distance from another vehicle is greater than a predetermined distance, transmits the stop signal to the brake system. 5. A method for preventing traffic signal violation using infrared communication, the method comprising the steps of: when a traffic light changes, transmitting traffic information in a traffic light controlling system; in a traffic signal violation prevention device, receiving the traffic information and, when the traffic information is stop signal information, generating and transmitting a stop signal; and in a brake system, receiving the stop signal to decelerate or stop a vehicle, wherein the traffic signal violation prevention device has a distance measurement unit for measuring a distance from another vehicle positioned in rear of the vehicle and, when the measured distance from another vehicle is greater than a predetermined distance, transmits the stop signal to the brake system. 6. The method according to claim 5, wherein the traffic signal violation prevention device detects a speed of the vehicle and, when the detected speed is less than a previously set speed, transmits the stop signal to the brake system. 7. The method according to claim 6, wherein the traffic signal violation prevention device has a distance measurement unit for measuring a distance from another vehicle positioned in rear of the vehicle and, when the measured distance from another vehicle is greater than a predetermined distance, transmits the stop signal to the brake system.
