Traffic control method based on traffic flow

Abstract

The invention discloses a traffic control method based on traffic flow. The traffic control method comprises idle-period traffic control and busy-period traffic control. An idle-period signal lamp time allocation scheme of the idle-period traffic control is a fixed-period control scheme made according to historical traffic data, there is only one idle-period time allocation scheme, and a signal lamp executes the idle-period time allocation scheme at the period of the idle-period traffic control; and the busy-period traffic control is intelligent control, effective regulation can be carried out on red-light signals and green-light signals of a traffic signal lamp according to real-time traffic flow, and the time length of conversion between a red light and a green light accords with traffic flow information at the moment. According to the invention, a margin is added when the time length of the green light is calculated at a signal lamp intelligent control center so that vehicles entering a road in a going-straight traffic period duration can all pass a crossing, the crowded city traffic status can be effectively improved, and traffic accidents are reduced.

Description

Technical field [0001] This application relates to the field of urban traffic control, and in particular to a traffic control method based on traffic flow. Background technique [0002] Traffic control, also called traffic signal control, or urban traffic control, is to rely on traffic police or use traffic signal control facilities to direct the passage of vehicles and pedestrians with the changing characteristics of traffic. [0003] Traffic control uses modern communication facilities, signal devices, sensors, monitoring equipment and computers to accurately organize and regulate the running vehicles, so that they can operate safely and smoothly. Traffic control is divided into static management and dynamic management, and traffic control is one of dynamic management. [0004] Traffic control restricts, regulates, induces, and diverts traffic flow through traffic control facilities managed by electronic computers to achieve the purpose of reducing the total amount of traffic, div...

Problems solved by technology

[0008] (2) Imbalance in traffic travel structure

The road network traffic capacity is significantly lower than the design requirements and has large fluctuations, travel time is difficult to predict, high traffic accidents, traffic environment deterioration, and travelers are prone to fatigue, etc.

[0010] In urban traffic, often due to the uneven distribution of traffic lights for straight, left and right traffic lights, vehicle congestion is often caused, and traffic accidents are prone to occur
