Design method of low-level road tunnel bend induction system

Abstract

The invention relates to the technical field of traffic safety, in particular to a design method of a low-level road tunnel bend induction system which comprises a plurality of cat eye spikes, a plurality of reflective rings, a plurality of reflective strips, a plurality of induction marks and a plurality of profile marks, wherein the cat eye spikes are arranged on sides of a lane and on two sides of a center separation line of the lane, the reflective rings, the reflective strips and the induction marks are arranged on side walls of the lane, the profile marks are arranged on the outer side wall of a maintaining roadway, and the induction marks correspond to the reflective rings to form an arrow-head structure. In order to solve the problems of monotonous tunnel bend visual environments, poor inductivity, easiness in deviating from the lane by drivers, collision with the side walls or driving into an opposite lane, the cat eye spikes, the reflective rings, the reflective strips, the induction marks and the profile marks are combined, and the requirements of the drivers for tunnel bend and ramp driving direction sense, speed sense and distance sense can be met, so that traffic safety of a low-level road tunnel bend section can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to a design method for a curve guidance system of a low-grade highway tunnel. The design method is adopted to effectively ensure the driving safety of the curve of the low-grade highway tunnel. Background technique [0002] Low-grade roads are similar to rural roads, and are defined as a general term for county roads, township roads, and village roads. The division is based on the administrative level of roads. Generally speaking, roads are mainly grades 3 and 4. With the rapid development of social economy, the number of rural motor vehicles in my country has increased sharply, but due to economic and technical reasons, the driving environment of low-grade roads and the driving level of rural drivers have not been improved accordingly, resulting in frequent traffic accidents on low-grade roads. [0003] Tunnels, curves, and ramps are typical traffic accident black spots. The...

Problems solved by technology

[0005] In view of the above problems, the present invention provides a low-grade road tunnel curve guidance system, aiming at the monotonous visual environment of the tunnel curve, poor inductivity, and the characteristics of the driver who is easy to deviate from the lane, hit the side wall or drive into the opposite lane, through the cat's eye The combination of road studs, reflective rings, reflective strips, guiding signs and contour signs can meet the driver's needs for sense of direction, speed and distance in tunnel curves, and improve traffic safety in low-grade road tunnel curves
