Embodiment Construction

[0027] See figure 1 , road traffic signal coordination real-time optimization control method, is characterized in that: it comprises the following steps

[0028] (1) The dynamic and static traffic scene calibration and recognition module calibrates and collects the dynamic and static traffic data of urban roads in real time. The dynamic and static traffic data includes macro traffic data and micro traffic data. The macro traffic data includes road network traffic conditions, key flow distribution, and traffic control Habits and traffic control needs, micro-traffic data include specific lane flow, intersection flow, vehicle queuing status and traffic flow status;

[0029] (2) The data analysis and in-depth research and judgment module conducts statistics, analysis and research and judgment on the dynamic and static traffic data, and obtains the results of the analysis and judgment; the statistics, analysis and research and judgment include the analysis of traffic flow operation...

Abstract

The invention provides a real-time road traffic signal coordination optimization control method and a control system thereof and solves problems that real-time optimization for control characteristic parameters such as a signal period and a green signal ratio according road traffic flow change can be not realized in a traffic signal control system mainly in a multi-period fixed signal timing mode; traffic pass efficiency and pass capability are not high; traffic congestion or even traffic jam can not be effectively ameliorated. According to an active optimization real-time driving system based on traffic data, macroscopic control strategies and microscopic tactical control strategies are made according to different dynamic and static traffic scenes, main-line coordination optimization control and real-time dynamic crossing optimization control are actively carried out, the control characteristic parameters such as the signal period and the green signal ratio are dynamically adjusted and generated, dynamic benefit evaluation is controlled through controlling operation characteristic indexes, and real-time coordination control is carried out through gradual operation monitoring and repeated optimization searching.

Description

technical field [0001] The invention relates to the technical field of road traffic signal control, in particular to the field of traffic signal control oriented to traffic scenarios and target strategies, specifically a road traffic signal coordinated real-time optimization control method and a control system thereof. Background technique [0002] The road traffic signal control system is the most basic and critical part of the intelligent transportation system. In order to effectively improve the travel efficiency of traffic participants, further alleviate the problem of urban traffic congestion, and adapt to the characteristics of China's traffic conditions and traffic control, the national All over the world are paying more and more attention to the upgrading, research and development and efficient application of road traffic signal control systems. However, the signal control system currently used in China is still mainly based on multi-period fixed signal timing, and t...
