Traffic signal control scheme switching adjustment management system and method

Abstract

The invention provides a management system and method for switching and adjusting traffic signal control schemes. On the basis of configuring traffic signal control benchmark schemes and realizing coordinated optimization of intersections, arterial lines, and areas, all benchmark schemes and optimized schemes are integrated and archived to realize The rapid change of the coordinated intersection signal control scheme during single-point center control; the system includes a reference scheme module, a coordination optimization module, a background scheme module and a central control module; The change of the signal control scheme affects the remaining signal control intersections within the coordination range, avoiding traffic congestion or other traffic problems caused by the coordination scheme still being implemented at the remaining signal control intersections, and reducing the workload of the traffic control department to change the signal control scheme of the coordination intersection in turn. Improve the efficiency of traffic signal control and ease the problem of traffic congestion.

Description

Technical field [0001] The present invention relates to a traffic signal control scheme switching adjustment management system and method. Background technique [0002] Since the 1990s, all levels of urban cities have been built with traffic signal control systems. As recent years of traffic congestion, the road and region coordinated optimization is continuously applied, so traffic signal control schemes and The scheduling management of the control method has become the basis for traffic signal control research. [0003] At present, the traffic signal control system represented by traffic signal manufacturers such as Hisense, Lees, Huatong can realize traffic signal control scheme configuration based on mobile / webpage, but there are shortcomings and problems, and line / region coordination. When optimized, the signal control scheme must be exported, and the information controller or the traffic control department will be optimized and then imported into each intersection, whic...

Problems solved by technology

[0005] The purpose of the present invention is to provide a management system and method for switching and adjusting traffic signal control schemes, which respectively carry out electronic management on the benchmark scheme, coordination optimization scheme and background scheme, realize the synchronous automatic adjustment of the central control scheme, and avoid the coordination involved in the central control The problem of road congestion caused by intersections reduces the workload of managers who need to readjust in turn, enhances the efficiency of traffic signal control, and solves the problem of switching between single-point signal control schemes and arterial / regional coordination schemes in the prior art. After adjusting to the single-point signal control scheme, it is necessary to pay attention to changing the remaining intersections, and the operation is cumbersome.
