The present application belongs to the technical field of traffic control, and in particular relates to a signal coordination control sub-area division method, device, computer-readable storage medium and terminal equipment. The method performs static division of the signal coordination control sub-area on the target area according to the preset historical path traffic flow data, and obtains the static sub-area division result of the target area; divides the static sub-area according to the predicted path traffic flow data The results are adjusted to obtain the dynamic sub-area division results of the target area. The method is based on the full amount of path data provided by traffic simulation technology, combined with the correlation model, and the coordinated paths in the divided sub-areas have continuous traffic requirements, which can maximize the benefits of green wave coordination, and are based on real-time online traffic simulation The rapid deduction ability, stronger real-time performance, can respond to changes in the actual road traffic flow state in a timely manner, and the dynamic sub-area division results match the traffic flow state, so as to achieve the best coordinated control effect.
Description
technical field [0001] The present application belongs to the technical field of traffic control, and in particular relates to a signal coordination control sub-area division method, device, computer-readable storage medium and terminal equipment. Background technique [0002] Coordinated traffic signal control is to control the entire traffic arterial line or the intersection group in a region as a whole, so that the vehicles passing through these intersections in turn can pass through the green lights all the way as far as possible, so as to improve the efficiency of vehicle traffic. The reasonable division of signal coordination control sub-areas is the premise of effective signal coordination control. According to the spatial geometric characteristics and dynamic traffic flow characteristics of signalized intersections and connected road sections in the control area, the entire control area is reasonably divided into several signal coordination areas. Control sub-areas, ...
