Embodiment Construction

[0033] The photoelectric induction system of low grade road tunnel of the present invention, as Figure 1-7 As shown, for low-grade highway tunnels (>1000m) with no lighting facilities or low lighting rate, considering the limited visual reference points obtained by drivers in the tunnel, which are prone to optical illusions and driving fatigue, combined with retroreflective technology With LED technology, based on the edge rate theory and the driver's visual needs, it is a reconstructed visual reference system for low-grade highway tunnels (>1000m).

[0034] Such as figure 1 , referring to the tunnel segmentation of tunnel lighting standards, combined with the monotonous environment in low-level tunnels (>1000m) and the characteristics of drivers prone to driving fatigue, the tunnel is divided into approach section, entrance section, transition section, middle section, exit section, The departure section, where: the middle section includes a reminder area and a wake-up area,...

Abstract

The invention discloses a low-grade highway tunnel photoelectric induction system. According to a highway tunnel (>1000 m) which is not provided with illumination facilities or is low in light-on rate, reflection rings, reflection strips and reflective track spikes are manufactured through the retroreflection technology, and a low-grade highway tunnel visual reference system is reconstructed by means of the mode combining multiple frequencies, multiple sizes, multiple shapes and multiple colors, LED induction marks and LED delineators; the tunnel is divided into an approaching section, an entrance section, a transition section, a middle section, an exit section and a bear-off section, wherein the middle section comprises reminding zones and awakening zones, the reminding zones are arranged in the tunnel every 500 m, and the awakening zones are arranged every two reminding zones or every 1500 m. Induction systems with similarity and differences are arranged according to characteristics of different sections. The defect that an existing low-grade highway tunnel is insufficient in illumination, poor in visual environment and insufficient in induction facility, and accordingly visual illusion is likely to be generated is overcome, and the driving safety of the tunnel is guaranteed.

Description

technical field [0001] The invention relates to the technical field of road tunnels, specifically for low-grade road tunnels (>1000m) without lighting facilities or with a low turn-on rate, and relates to a photoelectric induction system for low-grade road tunnels. Driving safety in the tunnel. Background technique [0002] my country's highway tunnels are developing rapidly, and the accident rate in tunnel sections is high, especially in long tunnels. As of the end of 2016, there were 15,181 highway tunnels and 14,039.7km in length across the country, an increase of 1,175 and 1,355.8km respectively compared with 2015. In addition, as of the end of 2016, there were 815 extra-long highway tunnels nationwide, with a length of 3622.7km, and 3520 long tunnels, with a length of 6045.5km. Relevant survey results by domestic scholars show that the accident rate of the tunnel section is 1.3-9.67 times that of the whole line, with an average of 5.17 times. The tunnel section i...
