The invention belongs to the technical field of traffic control, and particularly relates to a signal coordination control sub-region division method and device, a computer readable storage medium andterminal equipment. The method comprises the following steps: carrying out static division of a signal coordination control sub-region on a target region according to preset historical path traffic flow data to obtain a static sub-region division result of the target region; and adjusting the static sub-region division result according to the predicted path traffic flow data to obtain a dynamic sub-region division result of the target region. The method is based on total path data provided by a traffic simulation technology, a correlation degree model is combined, the coordination paths in the sub-regions obtained by division have continuous passage requirements, the green wave coordination benefit can be maximized, rapid deduction capability based on real-time online traffic simulation is stronger in real-time performance, change of the actual road traffic flow state can be timely responded, a dynamic subarea division result is matched with the traffic flow state, and an optimal coordination control effect is realized.
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, ...
