Coordination control method for area mixed traffic self-adaption signal

Abstract

An area mixed traffic self-adapting signal coordinated control method relates to the technical field of the automatic control, wherein the vehicle information for entering the control junction is detected through a detector, and the vehicle information is transmitted to the traffic signal controller; the traffic signal controller performs the preheating on the traffic flow data, while the area coordinated control computer analyzes the traffic flow operation state of each inlet section of the junction, to perform the realtime analysis forecast, provides the optimized traffic signal project timing parameters to the traffic signal controller. The method of the invention divided the city road net into a plurality of subareas, adopts the layer net working to coordinated control the duration time of the traffic light at each junction, advances the traffic capacity, prevents the traffic congestion, reduces the off gas, ensures the traffic safety.

Description

Technical field: The invention relates to the technical field of automatic control, and relates to a method for controlling urban traffic signals. According to the different states of urban road network traffic flow load and the operating characteristics of traffic flow, the signal timing parameters are automatically optimized, and the control strategy is selected according to the current traffic state, so that the control effect of the system can reach the optimal state. Background technique: In recent years, with the rapid development of my country's society and economy, the rapid advancement of urbanization, and the rapid expansion of urban population, this has led to a sharp increase in traffic demand brought about by the expansion of urban fringes and suburbanization of residences. At the same time, road traffic Insufficient facility supply, management, technology, and space make the contradiction between urban traffic demand and supply increasingly prominent. The rese...

Problems solved by technology

Therefore, these foreign advanced traffic signal control systems cannot fundamentally solve the mixed traffic congestion in cities in our country.

Moreover, the imported self-adaptive traffic control system cannot share information with other domestic systems, and cannot be re-developed. In the process of development and maintenance, high fees need to be paid
