Problems solved by technology

[0005] The technical problem to be solved by the present invention is that there is no lighting facility for short rural road tunnels, the tunnel environment is dark, the driver's visual environment is poor, and the driver is prone to optical illusions and miscalculation of speed and distance, which leads to common overspeed driving behaviors, rear-end collisions or Due to the technical problems of frequent accidents such as hitting side walls, a luminous induction system for rural road tunnels is proposed, which takes into account safety and energy saving, while avoiding optical illusions and ensuring safety. It is especially suitable for short rural road tunnels without electricity or lights ( <500m)

Embodiment 1

[0041] According to the present invention, the luminescence induction system for short rural road tunnels ( Figure 1-2 shown. Among them, the luminescence induction system for short tunnels less than 200m is composed of: peephole road studs 1 are set on the outside of the sideline of the lane, and the distance between the peephole road studs 1 on the same sideline is 2.5~4m, and the surface is made of high-strength reflective film; The self-illuminating outline marking line composed of two energy-storage self-luminous outline markers 5 arranged at intervals, the distance between each energy-storage self-luminous outline marker 5 on the same self-illuminating outline marking line is 2.5~4m, each energy-storage self-luminous outline marker 5 Located at the same horizontal position as cat's eye road stud 1 (with figure 1 The vertical direction of the road is horizontal), and the surface of each energy-storage self-illuminating contour mark 5 is made of energy-storing self-luminou...

Embodiment 2

[0043] According to the present invention, the luminescence induction system for short rural road tunnels (200-500m) is as follows: Figure 3-6 shown. Among them, the 200-500m short and medium tunnels are divided into different road sections: 1) The entrance section and the exit section are both 45-60m in length. , the exit section is the road section starting from 45-60m away from the tunnel exit in the tunnel, and the tunnel exit is the end point; 2) the middle section, the part of the tunnel section excluding the entrance section and the exit section is the middle section of the tunnel. 3) Reminder area, the midpoint of the reminder section is the midpoint of the tunnel section, and then the same distance is extended to the left and right respectively, and the length is one low-frequency design unit.

[0044] Furthermore, the design of the luminescence induction system for the entrance section and exit section of the 200-500m short tunnel is as follows: Figure 3-4 , cat'...

Abstract

The invention relates to a luminous induction system for rural road tunnels. According to the light environment characteristics of different sections of the tunnel, driving characteristics and visual characteristics of the driver, short tunnels are divided into short tunnels <200m and medium-short tunnels of 200-500m, and short tunnels of 200-500m are divided into: entrance section, middle section, In the exit section, multi-frequency and multi-size luminous induction facilities are set according to the characteristics of the road section; a reminder area is also set in the middle section; the high-frequency small-size induction information is set on the outside of the lane or at the maintenance road with the highest brightness, and the medium-frequency small-size induction information is set on The brightness of the side wall is lower than that of the curb induction information. The medium-scale induction information of the medium-frequency information is set on the side wall, and the low-frequency large-scale induction information is set on the side wall and extends to the top of the tunnel. Taking into account both safety and energy saving, while avoiding optical illusions and ensuring safety, it is especially suitable for short rural road tunnels (<500m) without electricity or lights.

Description

technical field [0001] The invention relates to the technical field of road safety, in particular to a luminous induction system for rural road tunnels (<500m) that guarantees driving safety in rural road tunnels. Background technique [0002] my country's highway tunnels are developing rapidly, and some provinces and cities have mostly short and medium tunnels, and the accident rate in tunnel sections is high. By the end of 2015, my country had 14,006 highway tunnels with a total length of 12,600 kilometers. Some provinces and cities, such as Zhejiang Province, have a large number of tunnels and the number of short and medium tunnels accounts for 80% of the total. In addition, the accident rate of the tunnel section is 1.3~9.67 times of the average accident rate of the whole line (5.17 times on average). [0003] The lighting rate of rural road tunnels is low, and the contradiction between safety and energy saving is prominent. According to the "Code for Design of V...
