Visual environment improvement design method of big and long highway tunnel based on rhythmical image

Abstract

The invention discloses a visual environment improvement design method of a big and long highway tunnel based on a rhythmical image. A lateral wall big rhythmical image curve and a lateral wall small rhythmical image curve are arranged at a lateral wall inside a tunnel. A road surface transverse visual illusion mark line and a road surface white broken line are arranged corresponding to the wave trough of the lateral wall big rhythmical image curve. The lateral wall is provided with a lateral wall vehicle distance indication mark line, thereby forming a spatial low-frequency visual information stream. A lateral wall annular mark line and two layers of outline marks are arranged in the tunnel; and three groups of road surface music note mark lines are corresponding to the lateral annular mark line; and a road surface protruded road sign is provided, thereby forming a spatial intermediate-frequency visual information stream. The lower edge of the kerbstone is provided with a red-and-white roadside vertical surface mark line, thereby forming a spatial high-frequency visual information stream. The rhythmical visual reference system consisting of the multiple frequencies of visual information effectively improves the sense of speed, the sense of distance, the sense of direction, and the sense of rhythm; and the method is applicable to the highway tunnel having a length more than 1000m, with the limit speed being 60-80km/h.

Description

technical field [0001] The present invention relates to the safety design of highway tunnels, in particular to a design for improving the visual environment of long highway tunnels based on the sense of rhythm and retroreflection, thereby improving the driver's speed perception and distance perception, and improving the driver's driving vision in long highway tunnels environment, which helps to realize the driving safety and comfort of drivers in long highway tunnels. Background technique [0002] Highway tunnels are often traffic bottlenecks on expressways, and their management level and service level directly affect the safe and smooth flow of expressways. The investigation of traffic accidents in 23 expressway tunnels by domestic scholars shows that accidents in tunnel sections are 1.3 to 9.67 times (average 5.17 times) the average accident rate of the entire line, and the ratios of the total number of accidents, number of injuries, deaths and economic losses are much hig...
