A kind of highway tunnel S-shaped curve curve inducing system and setting method

Abstract

The invention relates to the technical field of traffic safety, in particular to a highway tunnel S-curve bending guidance system and a setting method, comprises a reflective ring arranged on the tunnel contour wall, a reflective strip arranged on the side walls of the tunnel on both sides of the lane, an emergency guiding device arranged on the bottom of the reflective ring and the reflective strip, a strip-shaped reflective plate arranged on the surface of the inspection road edge, a double solid line arranged on the surface of the lane and an S-shaped curved road warning mark arranged on the side walls of the tunnel. As that reflective re is adopted, The combination of reflector, emergency guidance device, strip reflector, double solid lines and S-shaped curve warning signs can remind the driver of S-shaped curve and strengthen the curvature of S-shaped curve and the perception of speed, position and direction of the vehicle, so as to enhance the traffic safety of S-shaped curve ofexpressway.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to an S-shaped curve guidance system and a setting method for expressway tunnels. Background technique [0002] With the rapid development of my country's social economy, my country's road mileage and tunnel mileage continue to increase. However, due to the influence of the geographical conditions of the tunnel and the semi-closed nature of the tunnel, low-light operation of the highway tunnel often exists. An important reason for frequent accidents in tunnel sections. [0003] Tunnels and changing road sections are frequent spots of highway traffic accidents. Due to its monotonous environment, strong sealing, and poor light environment, the tunnel is a weak visual reference system. Drivers driving in the tunnel often cannot correctly judge the speed, position, direction, etc. of the vehicle due to the monotonous environment, and cannot correctly judge the tunnel. The correc...

Problems solved by technology

Due to its monotonous environment, strong sealing, and poor light environment, the tunnel is a weak visual reference system. Drivers driving in the tunnel often cannot correctly judge the speed, position, direction, etc. of the vehicle due to the monotonous environment, and cannot correctly judge the tunnel. correct alignment

However, at the lane change of ordinary road sections, because the line shape of the curve is different from that of the straight line, the driver often does not have enough sight distance and sight area, and there is a visual blind spot. The driver may not be able to correctly judge the curvature of the curve and cause the vehicle speed to High, it is very easy for the vehicle to deviate from the normal driving route of the curve and deviate from the lane or hit the side of the road

On the S-curve curve, the alignment is more complicated, and it is difficult for the driver to adapt to the sudden appearance of bad road alignment, which leads to traffic accidents.

If it is a combination of a tunnel and an S-shaped curve, the combination of poor visual reference and complex linear roads in the tunnel will cause the driver to have the illusion of a curve and underestimate the curvature of the curve. The direction and other information make wrong judgments, causing dangerous driving situations such as serious overspeeding and deviation from the normal driving route, which will eventually lead to serious traffic accidents such as the vehicle hitting the maintenance road or the side wall of the tunnel.
