The traffic efficiency, light at the intersection of the timing is very important. Traffic facilities persuation brigade has specialized technical personnel responsible for signal timing adjustment. Learned, intersection peak, peak of light phase timing is different, at present, the city's major
intersection traffic efficiency depends on the traffic lights. Traffic facilities training battalion has specialized technical personnel responsible for the traffic light timing adjustment. It is known that the phase of light timing in the intersection of flat peak and different time. Currently, the signal light in the urban areas are mostly controlled by microprocessor, can realize continuous automatic control throughout the day. Not only can adjust the timing of each cycle, and can accurately adjust the phase of a cycle time during the holidays. According to the traffic police and technical personnel, at present, many cities have begun to use advanced traffic signal remote intelligent control system. The system will signal and optical fiber connection, and then to transmit a signal to the remote control center. According to the center of each intersection traffic flow, vehicle queue length, such as traffic information, traffic signal timing scheme selected automatically, and the automatic control of motor vehicle road traffic light switching frequency and the realization of the traffic lights. If you have a car, it will be very long; If don't have a car, it will be short. In order to achieve the traffic lights; Intelligence; When times of trunk road traffic flow is relatively small, can realize the main traffic flow; Green wave area; In other words, a car can open a green light.
