An Induction System for Multifunctional Contour Belts in Extra-Long Tunnels

Abstract

The invention relates to the technical field of urban road traffic, in particular to an induction system for a multifunctional contour belt of an extra-long tunnel, which includes a tunnel entrance section, a tunnel transition section, a tunnel middle section and a tunnel exit section arranged sequentially from the tunnel entrance, and the tunnel middle section It is composed of normal area, reminder area, normal area, wake-up area, normal area, reminder area, and normal area, and the inner walls of the tunnel entrance and tunnel exit are respectively equipped with pentagonal reflective rings and pentagonal reflective strips The inner wall of the transition section of the tunnel is provided with a heptagonal reflective ring and the heptagonal reflective strip, and the inner wall of the middle section of the tunnel is provided with a small pentagonal reflective ring and a small pentagonal reflective strip. Both the polygonal reflective ring and the small pentagonal reflective ring are inlaid with LED light strips and a reflective film covered with light scattering holes reserved for LED light strips. The use of such a guidance system can effectively improve the driver's safe driving, and it is especially suitable for super-long highway tunnels with a single-hole two-way speed limit of 20-60km / h.

Description

technical field [0001] The invention relates to the technical field of urban road traffic, in particular to an induction system for a multifunctional contour belt of an extra-long tunnel, which is suitable for an extra-long highway tunnel with a single-hole two-way speed limit of 20-60 km / h. Background technique [0002] At present, tunnel safety accidents occur frequently. The reason is that the research on the tunnel is mostly focused on the lighting technology, and the induction of the line of sight is rarely involved, so the lighting in the tunnel is insufficient or the light is too strong. According to the intensity level of visual stimulation, it can be preliminarily judged: its illumination intensity, tunnel entrance section > transition section > middle section ordinary area, middle ordinary area < middle reminder area < middle awakening area. However, the current lighting technology does not predict the driver well at the entrance of the tunnel; at the s...

AI Technical Summary

Problems solved by technology

However, the current lighting technology does not predict the driver well at the entrance of the tunnel; at the same time, the driver is driving in the tunnel, driving in a dark, monotonous and lack of change environment for a long time, which is prone to driving fatigue

Therefore, the driver is often not very clear about the outline of the tunnel, and he has insufficient grasp of the width of the tunnel, which makes it difficult to ensure driving safety.
