Traffic lights generally refer to traffic signals, which are signals directing traffic to run, and are divided into: motor vehicle signal lights, non-motor vehicle signal lights, crosswalk signal lights, direction indicator lights (arrow signal lights), lane signal lights, flashing warning signal lights, road and railway plane crossing signal lights. Is generally composed of red light, green light and yellow light. At the crossroad, red, yellow, green and three-colour traffic signal lamps are hung on four sides, and it is a traffic police without sounding. Traffic lights are international unified traffic lights. The red light is a stop signal and the green light is a traffic signal. The vehicles in several directions are gathered at the intersection, some vehicles need to go straight, some vehicles need to turn, and the vehicles need to walk at first, so that traffic light command is needed.

When the vehicles in the direction a are rare, the signal green light is not passed through the vehicles in the direction a within the set time, and no vehicles enter the waiting area within the set time interval, the green light in the direction a can be changed into the red light, the red light in the direction b is changed into the green light, the remaining time is not left after the vehicles in the direction b start to pass through the crossing, the detection system can transmit the signal to the master controller in the first time, the master controller changes the signal lamp in the first time, and the direction a changes the red light and the direction b changes the green light. And b, passing the vehicle in the direction b, and if the number of vehicles in the direction b is particularly large, changing the signal lamp to the red lamp according to the set time of the local traffic management department. as does the a-direction. The number of the signal green lamps is less than the set time, the signal green lamps are not enough, no vehicles enter the waiting area within the set time interval, the detection system can transmit signals to the master controller at the first time, and the master controller changes the signal lamps at the first time to change the signal lamps into the red lamps from the direction b to the green lamps from the direction a. The green light of the signal in the direction b can be changed into the red light, the red light of the signal in the direction a is changed into the green light, and the vehicles in the direction a start to pass through the intersection, so that the alternating circulation is carried out.
If no vehicles exist in both directions, the local traffic department can set that both directions are yellow lights flashing or both directions are red lights lighting. Preferably, the red light is set in both directions, so that the safety of passing vehicles when the vehicles are rare can be ensured to the greatest extent.
The crossing with crosswalk is designed according to the width of the road, the crossing is strong in trafficability, the sectional passing mode is designed with high passing efficiency, and a pedestrian traffic light is arranged at the double yellow line in the middle of the opposite lane. And designing the pedestrian passing time according to the number of lanes and the width of the road.
Following the rule, twenty seconds are needed for the help to pass through four lanes, and for safety and quick passing, a single-step red light principle is adopted, namely: a traffic light is arranged at the opposite separation line in the middle of the road, when a turns to the left, b turns to the left hand of a of the central pedestrian light, the right hand square red, the forward pedestrian lamps b are red lamps, the forward left hand Fang Biandeng red lamp a, and the right hand square edge lamp a are red. Then, when the green light of the straight line is on, the green light of the pedestrian is on, when the red light of the pedestrian is on, the green light of the pedestrian is on, and when the red light of the pedestrian is on, the green light of the pedestrian is on, and the pedestrian is still passing through, but the pedestrian is not allowed to pass through, because the pedestrian is dangerous because the pedestrian is required to pass through the vehicle when the pedestrian turns left. b turning the red light to the left and turning the red light to the pedestrian to fully light. The primary green light quantity of the central traffic light of the pedestrian lamp and the secondary red light are lighted, and the pedestrian lamp circulates like a car lamp in the direction a and the direction b.
Example 2 the change of traffic light is controlled by the time the last vehicle passed the second a-forward detector 6, the fourth a-forward detector 8, the second a-reverse detector 10, the fourth a-reverse detector 12, the second b-forward detector 14, the fourth b-forward detector 16, the second b-reverse detector 18, the fourth b-reverse detector 20.
