Induction system for multifunctional contour belt of extra-long tunnel

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 comprises a tunnel entrance section, a tunnel transition section, a tunnel middle section and a tunnel exit section which are sequentially arranged from a tunnel entrance. The tunnel middle section is composed of a common area, areminding area, a common area, a wakeup area, a common area, a reminding area and a common area which are sequentially arranged, pentagonal reflective rings and pentagonal reflective strips are arranged on the inner wall of the tunnel entrance section and the inner wall of the tunnel exit section respectively, and heptagonal reflective rings and heptagonal reflective strips are arranged on the inner wall of the tunnel transition section. A small pentagonal reflective ring and a small pentagonal reflective strip are arranged on the inner wall of the middle section of the tunnel; LED lamp strips and reflective films are embedded in the pentagonal reflective ring, the heptagonal reflective ring and the small pentagonal reflective ring; and lamplight scattering holes of the LED lamp strips are reserved in the peripheries of the reflective films. By the adoption of the induction system, safe driving of a driver is effectively improved, and the guidance system is particularly suitable for ahighway extra-long tunnel with the single-tunnel two-way speed limit ranging from 20 km / h to 60 km / h.

Description

Technical field[0001]The invention relates to the technical field of urban road traffic, in particular to a guidance system for a multi-functional contour zone of an extra-long tunnel, which is suitable for a single-hole two-way speed limit of 20-60km / h in a highway extra-long tunnel.Background technique[0002]At present, tunnel safety accidents happen frequently. The reason is that the research on the tunnel is mostly focused on the lighting technology, and the guidance of the sight line is rarely involved, which leads to insufficient lighting or too strong light in the tunnel. According to the level of visual stimulus, it can be preliminarily judged: its lighting intensity, tunnel entrance section>Transition section>Central general area, central general area<Central reminder area<Central wake area. However, the current lighting technology at the entrance of the tunnel does not predict the driver well; at the same time, the driver driving in the tunnel for a long time in...

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.
