Traffic Control System

Urban Traffic Signal Self-Adaptive Coordinated Traffic Control System

Cooperate with the detection devices equipment at each intersection in the region to ensure the coordination of the trunk lines while performing self-adaptive control at the intersections.

Detection equipment is installed at each intersection in the region to ensure coordination of the trunk lines while performing self-adaptive control at the intersection.When there is a need to reduce the green light in the non-coordinated direction, the reduced green light time will be automatically transferred to the coordinated direction to ensure that the cycle remains unchanged. Multiple basic schemes for common cycles are configured for each intersection. Each intersection selects the corresponding common cycle scheme according to its traffic flow, saturation, queue length and other parameters of the key intersections in the line. Each intersection performs self-adaptive coordinated control under the new common cycle scheme. When the coordination value of a certain direction is not high, it automatically converts to reverse one-way coordination; When the coordination value of both directions of the line is not high, the coordination automatically disconnects and converts to regional balancing control or overflow control.

Self-Adaptive Control

The central control computer calculates the green light demand in each direction based on the traffic flow data fed back by the vehicle detectors installed at each intersection, such as traffic flow, time occupancy, space occupancy, queue length, automatically selects the appropriate timing parameters, and realizes real-time control of traffic signals at intersections and road networks based on the selected timing parameter combination.

Dynamic Coordinated Control

Vehicle detection equipment is installed at all intersections or key intersections or routes in the trunk line to coordinate the intersections of the route, preset multiple coordination schemes, and automatically calculate the phase difference. The central system selects the appropriate coordination scheme to run according to the traffic conditions at each intersection or key intersections. Each intersection adjusts the green light time in each direction according to the traffic conditions in each direction without changing the cycle, making the intersection more efficient while ensuring the coordination of the trunk line. According to the judgment of the two-way traffic conditions of the route, when the coordination value of a certain direction is not high, it automatically converts to reverse one-way coordination; When the coordination value of both directions of the line is not high, the coordination automatically disconnects and converts to regional balancing control or overflow control.
