Problems solved by technology

This means that there is no vehicle passing through this lane for a period of time, resulting in a waste of road resources
If the switching frequency of the variable lane direction increases, the clearing time will also increase, which will cause greater waste of road resources and greater delays

Embodiment Construction

[0039] The present invention will be further described below in conjunction with specific examples.

[0040] According to the variable lane driving direction switching method based on tracking the position of vehicles on the lane, the basic idea of ​​the present invention is to track the last vehicle LV running in the original driving direction on the variable lane, and by changing the state of the variable lane markings, allowing After the opposite vehicle changes lanes to the last body, the waste of road resources is reduced and the efficiency of lane change is improved.

[0041] Such as figure 1 As shown, the described variable lane driving direction switching method based on tracking the vehicle position on the lane comprises the following steps:

[0042] 1) Receive a variable lane direction switching command.

[0043] 2) Find and track the last vehicle LV in the variable lane, and mark its position as S 1 , where the last vehicle LV in the variable lane is defined as: ...

Abstract

The invention discloses a variable lane driving direction switching method based on the vehicle position on a tracking lane. According to the method, an LED light is applied to the field of lane markings for the first time; a variable lane gantry and a signal light are used as road guidance; according to the real-time locations of vehicles on a road and the road conditions, by tracking the location of the last vehicle LV in a variable lane, the gantry signal light and dashed and solid lines of the lane markings are controlled; and the road resource behind the last vehicle LV driving in the original direction in the variable lane is fully used to improve the operation efficiency. The variable lane driving direction switching method provided by the invention is suitable for variable lane roads of a variety of numbers of lanes, and has the advantages of improved road utilization, good economic benefit, being universal and the like.

Description

technical field [0001] The invention relates to the technical field of dynamic traffic management, in particular to a method for switching the driving direction of a variable lane based on tracking the position of vehicles on the lane, which can be used for direction switching in the process of dynamic control of the driving direction of the variable lane. Background technique [0002] In recent years, with the rapid development of the national economy and the acceleration of urbanization, serious traffic tides have emerged between urban centers and residential areas. In order to solve this problem, variable lanes came into being, which can flexibly evacuate congested vehicles by controlling the driving direction of the lanes to change the traffic capacity in both directions. Although variable lanes can improve efficiency as a whole and are advanced, it has been found carefully that the way of changing the direction of the road during the operation of variable lanes is very ...
