Expressway rear-end collision prevention marking line design method based on inverse linear perspective

Abstract

The invention discloses a highway rear-end collision prevention marking line setting method based on inverse linear perspective, and the method comprises the steps: designing fishbone-shaped marking line groups, designing the angle of each fishbone-shaped marking line in the marking line groups according to the inverse linear perspective principle, and enabling the angles of the fishbone-shaped marking lines in the same marking line group to be sequentially increased in the driving direction; determining the length of the single marking line group; designing marking line sections, each marking line section comprises a plurality of marking line groups, and determining the group distance S2 between every two adjacent fishbone-shaped marking line groups according to visual instantaneous memory; according to the parking sight distance of safe driving, determining the section distance S3 between every two adjacent marking sections; and laying the designed marking lines on an exit lane 650-700m away from the exit of the expressway along the driving direction. The method has the advantages that the inverse linear perspective theory is combined with the fishbone-shaped marking line with the good speed reduction effect, the vehicle following distance is increased while a driver is induced to actively reduce the speed, and rear-end collision accidents on the expressway can be reduced.

Description

technical field [0001] The invention relates to the technical field of traffic, in particular to a method for designing expressway anti-rear-collision markings based on inverse straight-line perspective. Background technique [0002] Statistics on traffic accidents at home and abroad show that among all accidents, vehicle rear-end collisions are the main accident form; and the cause of rear-end collisions is largely due to the driver's speeding and failure to maintain a safe distance between vehicles. Under high-speed driving conditions, the driver subjectively judges the distance between vehicles and the speed of the vehicle with great deviation, which usually manifests as overestimation of distance and underestimation of speed. Therefore, how to effectively control the speed of vehicles and maintain a reasonable distance between vehicles is the key to reducing rear-end collision accidents and improving the safety status of existing expressways. [0003] In order to improv...

However, the various pavement markings that are currently widely used only consider the aspect of speed reduction, and do not comprehensively consider the two aspects of speed reduction and increasing the following distance.
