Embodiment Construction

[0043] Such as figure 2 , the supporting equipment of the hybrid traffic adaptive signal coordination control method described in this aspect is composed of a detector 1, a traffic signal controller 2, a traffic database server 3, a regional coordination control computer 4, a traffic information management computer 5, and these devices are connected and responsible for Data transmission is composed of data communication control machine 6.

[0044] Detectors mainly include vehicle detectors (including induction coils, radar, infrared and acoustic wave detectors), usually induction coils, non-motor vehicle detectors (mainly bicycle detectors), and emergency vehicle and public vehicle detection systems (by unit and external unit).

[0045] The traffic signal controller adopts an intelligent traffic signal control machine and adopts a 6U standard structure, such as image 3 Shown, take PC104 as the embedded chip of the main control unit. Its functional modules such as Figure...

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: [0001] 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: [0002] 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 promi...
