Traffic light control system suitable for intersection control

Abstract

The invention relates to a traffic signal control system suitable for controlling a jammed intersection, which comprises a central control unit for controlling traffic lights and a camera for monitoring an intersection and for monitoring traffic conditions on a road in each steering direction, traffic pictorial information of the intersection and the road in each steering direction is obtained through the camera for monitoring thereof and transmitted into the central control unit after the traffic pictorial information is converted through a converting circuit, after the traffic pictorial information is processed through the central control unit, the jam situation of the intersection and the road in each steering direction is judged, the traffic lights controlled in the corresponding steering direction in the jam state are arranged and maintain in the state that the red light is on, and the original conversion manner of the traffic lights is restored again until the jam state is eliminated. The control system can automatically arrange and maintain the traffic signal into the signal of the red light according to the jam situation of the road in various directions under the condition that the intersection can be congested due to steering intersection by the vehicles, so that the vehicles are forbidden to steer and the intersection congested is avoided, so as to ensure unimpeded intersection.

Description

technical field [0001] The invention relates to a traffic signal lamp control system suitable for the control of congested intersections, mainly used for controlling traffic signal lamps. technical background [0002] Whether the control of traffic lights or traffic lights is reasonable is an important factor affecting the traffic capacity of road intersections. The existing traffic light control system is set in the traffic light control cabinet located on the side of the traffic light road, and the traffic lights are controlled by the central control unit. Conversion, the control system is equipped with a mode setting device and a manual switch device, through the mode setting device input control parameters such as traffic light conversion sequence and conversion time, through the manual switch device to realize the direct control of traffic lights by people, without manual operation , the traffic lights will change the signal according to the set program and install a fi...

Problems solved by technology

The defect of this technology is that when the opposite road is congested and the vehicles entering the intersection cannot continue to drive, it will block the vehicles from other directions, and the vehicles from all directions will enter and stop in the intersection, "inserting" the entire intersection.

In order to avoid this situation, the relevant departments stipulate that when the opposite road is congested and vehicles may not be able to drive out of the intersection, vehicles that have not entered the intersection are not allowed to enter the intersection even when the green light is on, but this regulation is actually implemented. It is difficult to get up, because the driver's field of vision is blocked by the vehicle in front, and he cannot make an accurate judgment on the entire road situation. When driving slowly, he cannot be sure whether he can drive out of the intersection after entering the intersection. At this time, if the driver drives , you may have to face penalties for obstructing road traffic due to intersection congestion. If you stop driving, it may cause unnecessary waste of time and block the driving of subsequent vehicles, which also forms an obstacle to road traffic.
