Intersection traffic signal control method, device and equipment

Abstract

The invention discloses an intersection traffic signal control method, device and equipment. The method comprises the following steps: presetting motor vehicle traffic flow, non-motor vehicle trafficflow and conflict relationship of the traffic flow at an intersection; acquiring flow ratio data of all motor vehicle traffic flow; automatically generating signal lamp phase parameters according to the flow ratio data, the motor vehicle traffic flow, the non-motor vehicle traffic flow and the conflict relationship and the traffic flow participation sequence; performing phase sequence optimizationon each target phase in the signal lamp phase parameters, and determining a release sequence of each target phase; solving a signal lamp control period and green light time of each target phase basedon a signal timing method and a signal lamp phase parameter; and controlling the intersection traffic signal by using the obtained signal lamp control period, the release sequence of each target phase and the green light time. The intersection traffic signal can be simply, efficiently and safely controlled, and a reliable and better guarantee is provided for traffic operation.

Description

technical field [0001] The invention relates to the field of traffic signal control, in particular to a traffic signal control method, device and equipment at an intersection. Background technique [0002] With the rapid development of my country's economy, the continuous expansion of urban scale, and the sharp increase in the number of motor vehicles, in order to ensure the safe, orderly and smooth operation of urban traffic, traffic signal control at intersections is indispensable. At present, the problem of urban traffic congestion and traffic signal control at intersections has attracted the attention of many researchers. Under the condition that the channelization of urban roads remains unchanged, the optimization of traffic signals plays an active role in how to reduce congestion and maintain smooth flow. .

Problems solved by technology

[0003] Traffic operation at intersections in the city is traditionally commanded by the police at the intersection, or the police at the intersection summarize the characteristics of the traffic flow based on their work experience, and then solidify it into the signal machine for automatic execution. However, the above-mentioned methods are not only inefficient but also difficult to adapt Intersections with large traffic flow changes and newly constructed intersections

[0004] With the continuous advancement of the construction of smart cities and intelligent transportation, the application of big data and artificial intelligence has been implemented one after another, the collection and processing technology of traffic big data is becoming more and more mature, and the use of traffic big data to automatically guide urban traffic operations can reduce congestion. Automatic control schemes to ensure traffic safety have also emerged as the times require. However, the existing automatic control schemes for traffic signals at intersections are often too complex, with too large phase combination space, which increases the difficulty of solving, and reduces the traffic operation efficiency and efficiency of intersections from the side. safety
