Traffic signal control method of lane borrowing passing in closed construction area of highway

Abstract

The invention discloses a traffic signal control method of lane borrowing passing in a closed construction area of a highway. The traffic signal control method comprises the following six steps: traffic data acquisition, borrowed lane quantity determination, stop line position determination, lane-changing forbidding area length determination, signal control scheme determination and right of way distribution. Through the acquisition of traffic flow information of the upstream section of a unidirectional full-closed construction area of the highway, the borrowed lane quantity needed when a vehicle influenced by closed construction passes on an opposite lane is determined, and the stop line position and the lane-changing forbidding area length of the lane influenced by closed construction are determined. Through the signal control scheme provided by the traffic signal control method, traffic flow rights of way of the unidirectional full-closed construction area of the highway are sequentially distributed. The bidirectional traffic flow passing in the unidirectional full-closed construction area of the highway is controlled by a signal, the phenomenon of the free crossing of vehicles, which is caused by that vehicles are decreased, is reduced, the safety of traffic operation is improved, and therefore, the traffic signal control method has practical significance.

Description

technical field [0001] The invention belongs to the field of road traffic operation and organization technology and traffic control, and relates to a traffic signal control method for passage in closed construction areas of expressways. Background technique [0002] Expressways are high-grade highways, which refer to highways that can adapt to the annual average day and night passenger car traffic volume of more than 25,000 vehicles, are designed for high-speed driving in separate lanes, and all access and exit are controlled. In recent years, with the rapid development of my country's national economy, the mileage of expressways has increased rapidly, and the traffic volume of expressways has also shown a trend of continuous growth. However, the rapid increase in traffic volume and the increase in heavy-duty vehicles have damaged the road surface conditions and traffic facilities of some expressways to varying degrees. The task of expressway reconstruction and expansion is ...

AI Technical Summary

Problems solved by technology

Although this method reduces the difficulty of operation, it is more achievable on the surface, but in the process of free interweaving of high-speed vehicles, the lane that is borrowed becomes shared by the traffic flow of multiple lanes. The interweaving behavior has huge potential traffic safety hazards

In addition, when the vehicles blocked due to construction use the passage, they have to wait until there is a large traversable gap in the lane being borrowed, which reduces the traffic efficiency of the vehicles.
