Embodiment Construction

[0042] see figure 1 , which is a composition diagram of a site-level traffic signal coordination system for this application;

[0043] Depend on figure 1 It can be seen that the embodiment of the present application provides a field-level traffic signal coordination system, the system includes a central control unit, a plurality of regional control units and a plurality of intersection control units; unit connection; each of the regional control units is respectively connected to several intersection control units; in this embodiment, through the tree-like hierarchical control, the overall regulation and control of all intersections by the central management and control system has been improved into centralized control, The hierarchical management and coordinated linkage control mode, on the one hand, can reduce the complexity of system-wide hardware and software operating status monitoring and troubleshooting, and on the other hand, it is more convenient for the overall opti...

Abstract

The invention relates to the technical field of the traffic signal control, and specifically discloses a field level traffic signal coordination system and device. The system comprises a center control unit, multiple region control units and multiple intersection control units; multiple region control units are connected with the center control unit; each region control unit is connected with a plurality of intersection control units; the device comprises a server arranged in an intersection signal controller crate; a data receiving unit, a network transmission unit and a data processing unitare configured in the server. Under a large-scale road network condition, various intersections of the city are decomposed of a plurality of sub-areas by adopting a hierarchical dispersed control, theintersection number in the sub-area is relatively small, the vehicle dissipation in each intersection in the control region can be balanced by combining the accurate traffic flow data and adopting aregion dynamic coordination algorithm, the region coordination control is really realized, thereby realizing more precise region traffic optimal configuration.

Description

technical field [0001] The present application relates to the technical field of traffic signal control, in particular to a field-level traffic signal coordination system, and also relates to a field-level traffic signal coordination device. Background technique [0002] In recent years, with the rapid growth of urban population and motor vehicle ownership, urban traffic problems have further aggravated. The use of intelligent traffic signal control systems can scientifically allocate traffic rights and improve traffic order, thereby improving traffic capacity and traffic efficiency at road intersections. , reduce traffic delays and resource waste, and effectively alleviate traffic congestion while improving the carrying capacity of regional and urban road networks. [0003] Most of the intelligent traffic signal control systems in the prior art adopt a centralized coordinated control strategy as an important support for the intelligent timing of traffic signal lights. The ...
