Abstract

The invention relates to the technical field of long and big tunnels of expressways, in particular to a method for setting a retro-reflecting system of a long and big tunnel of an expressway. The method for setting the retro-reflecting system of the long and big tunnel of the expressway comprises the following steps of dividing the long and big tunnel into an entrance section, a transitional section, a middle section, a middle warning section and an exit section in sequence; respectively using combinations of an intermediate frequency reflective ring, an intermediate frequency side wall inducement sign, a high frequency delineator and a high frequency road stud at the entrance section and the exit section; using the combination of the intermediate frequency reflective ring, an intermediate frequency reflective stripe, the intermediate frequency side wall inducement sign, the high frequency delineator and the high frequency road stud at the transitional section; using the combination of a low frequency reflective ring, a low frequency note mark line, the intermediate frequency reflective stripe, the intermediate frequency side wall inducement sign, the high frequency delineator and the high frequency road stud at the middle section; continuously arranging two colored reflective rings as the middle warning section in the middle section; and arranging rhythm type information, the colored reflective ring and a colored reflective stripe on the side wall as a fatigue awakening area every three warning sections. The method for setting the retro-reflecting system of the long and big tunnel of the expressway is applied to expressway tunnels with limited speeds of 60-80 km / h and lengths of larger than 1000 m.

Description

technical field

[0001] The invention relates to the technical field of long and long expressway tunnels, in particular to a method for setting up a retroreflective system of long and long expressway tunnels. Background technique

[0002] Traffic accidents frequently occur in tunnel sections, and the main cause of traffic accidents is speeding behavior, while 70% of expressway speeding behavior is induced by speed illusion (insufficient sense of speed). The main cause of accidents such as rear-end collisions and side wall collisions in tunnels is the lack of sense of distance, which can not accurately determine the distance between the car and the car in front and the distance between the car and the side wall, resulting in serious illusions. At the same time, the driver's driving trajectory deviates from the current lane, and the lane keeping ability is insufficient. The main cause is insufficient sense of direction. At the same time, when driving in tunnel groups, especial...
