Embodiment Construction

[0016] Such as figure 1 As shown, a kind of regional boundary traffic signal coordinated control method based on organic computing of the present invention is made up of six parts such as traffic monitoring module, self-optimization module, self-organization module, evolutionary learning module, self-assessment module and self-setting module, The specific process of its work is:

[0017] 1) Traffic monitoring module

[0018] The data sources of the traffic flow monitoring module include real-time data from traffic detectors near local intersections, real-time traffic data transmitted from adjacent intersections, and historical traffic data extracted by the control center. A spatio-temporal resource mapping model of traffic flow is formed, and on this basis, multi-source traffic data fusion, traffic state discrimination and traffic flow operation situation estimation are carried out. The data processing flow of the traffic monitoring module is as follows: figure 2 As shown,...

Abstract

The invention provides an organic calculation based coordination control method for a traffic signal of a zone boundary and relates to the field of urban traffic signal control and manual intelligence. A device comprises a traffic flow monitoring module, a self-optimizing module, a self-organizing module, an evolution learning module, a self-assessment module and a self-setting module. According to the method provided by the invention, the coordination among intersections of the zone boundary is realized and the traffic jam at the intersections of the zone boundary is avoided.

Description

technical field [0001] The invention relates to the fields of urban traffic signal control and artificial intelligence, in particular to a traffic signal coordinated control method. technical background [0002] At present, traffic signal control systems at home and abroad are independently controlled by region. Each traffic signal control region optimizes and coordinates the intersection traffic signal scheme according to the road traffic flow information in the region. The traffic between regions Signal control "independently, without interfering with each other". At the regional boundary, the boundary intersections and their traffic flow information belong to different control areas, and the respective areas shall optimize the traffic signal timing parameters of the boundary intersections according to the traffic flow operation status of the area. However, due to the differences and correlations between population distribution, land use, economic development, and traffic...
