Real-time distribution control method of road traffic signal lamp

Abstract

The invention relates to a real-time distribution control method of a road traffic signal lamp, electromagnetic induction signals are utilized for identifying traffic flow, real-time reasonable distribution of road resources is performed according to the traffic flow so as to achieve the purpose of realizing intelligent control of the traffic signal lamp (namely, green ratio), and the real-time distribution control method is applied in the field of management of transportation technologies of public roads and urban roads. By adopting the real-time distribution control method, the road resources and vehicle resources can be reasonably integrated, driving is safer, more convenient, fast and smooth, the labor intensity of polices and transportation management staff is effectively reduced, the waste of energy of vehicles is simultaneously reduced, and the utilization rate of the road resources and the vehicle resources is improved.

Description

Real-time distribution control method of road traffic signal lights technical field The invention relates to a real-time distribution control method for road traffic signal lights, which uses electromagnetic induction signals to identify traffic flow, real-time and reasonable distribution of road resources according to the traffic flow, and achieves the purpose of intelligently controlling traffic signal lights. It is mainly used in road and urban road traffic technology management field. Background technique At present, highway and urban road traffic congestion is a common problem in all large and medium-sized cities in the world, and even becomes a bottleneck restricting urban development. On the one hand, the reason is the increase in the number of vehicles, and on the other hand, it is caused by the unreasonable allocation of road traffic resources. Except for a very small number of manual command offices in China, the general road resources are allocated by traffic li...

Problems solved by technology

Due to the different functions of urban areas and different time periods, the traffic flow in all directions on the road is not the same. When the traffic flow at each traffic intersection is greatly different, the technical defects are highlighted, such as; When there is little or no traffic in the north direction, the switching time of the signal light remains unchanged, and the side with a large traffic volume is likely to cause traffic congestion, which in turn leads to traffic jams

The technology of simple time program control cannot adjust and change the signal light switching time (ie: green signal ratio) according to the size of the traffic flow, which often leads to waste of traffic road resources, vehicle resources and energy.

In addition, when driving at night, there are often no vehicles passing through other intersections, and waiting for red lights occurs at intersections with vehicles. This situation of waiting for red lights is easy to cause drivers to ignore the management of signals when driving at night. Forcibly running a red light under the condition of vehicles at other road intersections, thus causing traffic accidents
