Method and system for controlling flow dividing at crossroad through traffic lights

Abstract

The invention discloses a method for controlling flow dividing at a crossroad through traffic lights, and the method specifically comprises the following steps: (1), turning off the green light in advance if there is no vehicle at one side of a first trunk line, wherein the first trunk line and a second trunk line are interlaced at a main intersection; (2), turning off the green light in advance if there is no vehicle at one side of the second trunk line; (3), enabling a light board to be yellow because a main road light board at an intersection of an auxiliary road is also yellow under the normal condition, enabling the yellow light of the main road to turn green once a person on the auxiliary road presses the button, and enabling the green light to turn red after 20S, wherein when the light on the main road turns red, the light board of the auxiliary road turns green. The invention also discloses a system employing the method. Speed bumps are laid in the range of 200m from the main intersection on the first and second trunk lines, and are provided with resistive strain weight sensors. Monitoring devices are respectively disposed above a waiting lane of the first trunk line and awaiting lane of the second trunk line which is 200m far from the main intersection. The method and system improve the traffic efficiency, and guarantee the safety.

Description

technical field [0001] The invention relates to the field of urban traffic, in particular to a traffic light diversion control method at a crossroad and a control system thereof. Background technique [0002] With the continuous rapid development of my country's economy, the urban area has doubled or dozens of times, and people's lives have become more and more prosperous. Many people have lived a life of "having a house and a car". The rapid increase, the increase in the number of cars has brought convenience to people's travel, but also increased the pressure on transportation. Due to the rapid development of motor vehicles, insufficient road construction, low public transportation share, and unreasonable urban layout structure, the problems of road congestion, vehicle congestion, and traffic disorder are becoming more and more prominent, seriously affecting the process of economic construction. However, in some road sections, especially near schools, traffic jams will be ...

Problems solved by technology

Due to the rapid development of motor vehicles, insufficient road construction, low public transportation share, and unreasonable urban layout structure, the problems of road congestion, vehicle congestion, and traffic disorder are becoming more and more prominent, which seriously affects the process of economic construction.

However, in some road sections, especially near schools, traffic jams will be covered after the peak hours of school and school leave. The traffic lights are still too long, and the jump cycle is consistent with the morning rush hour. The waiting time is 1.5min to 3min. This is not conducive to normal traffic

In addition, at the intersection of auxiliary roads, pedestrians want to cross the road. Since there are always vehicles passing on the main road, pedestrians can only pass by forcefully according to the traffic regulations. Once the driver rushes to pass, this will lead to traffic accidents.
