Control method for eliminating traffic jam of expressway principal line toll station through flow

Abstract

The invention discloses a control method for eliminating traffic jam of an expressway principal line toll station through flow. At first, a real-time occupancy rate value is automatically obtained through a traffic flow detector arranged on a downstream road section of the expressway principal line toll station, whether the current traffic flow operation condition of a downstream principal line entrance is of supersaturation or not is judged through an occupancy rate, vehicle passing rates of current toll gates are automatically calculated through a control algorithm, and a cycle of a rising-falling rod is automatically controlled, so the fact that traffic jam is generated in principal line downstream due to excessively high vehicle passing rates at the toll gates is avoided. Therefore, the vehicle passing flow rate and the expressway passing efficiency are reduced. The control method overcomes the detects that the traffic jam is generated in the downstream due to the excessively high vehicle passing rates at the expressway principal line toll gates, can achieve maximization of the expressway principal line passing efficiency through automatic control, is easy to implement, and has a widely applied range and good application prospect.

Description

technical field [0001] The invention relates to a traffic flow control method for a highway main line toll station for eliminating traffic congestion, which automatically controls the vehicle passage rate of a main line toll gate according to the current traffic flow operating state, and belongs to the technical field of traffic management and intelligent transportation. Background technique [0002] In the past two decades, my country's highway construction has developed rapidly. By the end of 2011, the total mileage of my country's highways reached 85,000 kilometers, ranking second in the world. With the development of social economy and the increase of residents' income, the level of motorization in my country has developed rapidly, and the number of motor vehicles has increased rapidly. By the end of 2011, the number of motor vehicles in the country was 225 million, of which 106 million were cars; The number of people reached 236 million. With the development of expressw...
