Graded Design of Intelligent Traffic Signal Control System

As we all know, the use of intelligent traffic signal control systems is required during the use of traffic lights. Intelligent traffic signal control system is a signal control subsystem for intersections, pedestrian crossings, and loop exits in urban road traffic management systems. It uses traffic engineering, psychology, applied mathematics, automatic control, and information network technology. System engineering and other multidisciplinary application systems. So do you know what the graded design of the intelligent traffic signal control system is?

The basic steps:

According to traffic flow status and prediction at intersections, traffic channelization is designed to analyze the original traffic flow data, and the simulation model is used to determine the control mode, and the traffic parameters are set. The traffic engineering design (including vehicles) is completed according to the traffic channelization design and the design requirements of the control mode. Detector's detection area positioning) According to the correlation of equipments at each intersection, the optimization objective function of the coordination design determination system and the single point control is completed, and the optimized signal control scheme is configured to solidify the basic parameters of the intersection signal controller and configure the master control. Central database and data transmission settings.

Operation management and hierarchical control:

The operation and management of the signal control system mainly includes data updating of the operation platform including the main control center database including geographic information, and the maintenance and effectiveness of the intersection facilities, especially the vehicle detection equipment, to ensure the soundness and accuracy.

As the construction of traffic signal control systems is closely related to urban planning and road planning, and there are certain constraints on the construction and improvement of facilities, it is impractical to get them in one step. Therefore, the management mode of intelligent traffic signal control systems is centralized management. Control, make full use of existing facilities, and conduct self-adaptive coordination of individual intersections according to the actual traffic conditions, followed by coordinated control of the main lines, and achieve distributed and coordinated hierarchical control, and finally reach the optimal regional control system.
