Tunnel back reflection illuminating system setting method based on train speed control and train distance keeping

Abstract

The invention discloses a tunnel back reflection illuminating system setting method based on train speed control and train distance keeping. The method comprises the steps of: arranging tunnel side walls, red and white facade marked lines on lower edges of curbs, and road surface raised pavement markers on road sides to form a space high-frequency vision information stream; secondly, arranging a plurality of layers of outline markers on the tunnel side walls at intervals of 25-50m in an advancing direction, arranging side wall vertical marked lines and extending to the top of a cave, transversely arranging transverse wrong vision marked lines on the road surface to form a space medium-frequency vision information stream; and then arranging two white folded lines and vibration marked lines on the road surface every 3 medium-frequency transverse marked lines at intervals of 100-200m in the advancing direction, and arranging two white folded lines on the side walls to form a space low-frequency vision information stream. Multiple channels of frequency vision systems are made of a high-strength back reflection material, so that a back reflection illuminating system is formed, perception of velocity and perception of distance of a driver are effectively improved, thus the integration of tunnel illuminating benefit and tunnel safety is achieved. The tunnel back reflection illuminating system setting method can be applied to tunnel illumination of low-light expressways with speed limit of 60-80km / h and traffic safety facility improvement.

Description

[0001] technical field [0002] The invention relates to a setting method of a tunnel retroreflective lighting system that improves the driver's vehicle speed control and vehicle distance maintenance capabilities, so as to realize the coordination of tunnel lighting energy saving and tunnel traffic safety benefits. Background technique [0003] The operating lighting of the tunnel section is insufficient, speeding is common in the tunnel, and accidents of rear-end collisions and side walls are frequent. The "JTJ026.1-1999 Design Code for Ventilation and Lighting of Highway Tunnels" promulgated in 1999 and the "JTG / T D 71-2004 Code for Design of Road Tunnel Traffic Engineering" promulgated in 2004 have made the configuration of electromechanical facilities of road tunnels in my country reach a very high level. Level. For highway tunnels, according to my country's national standards, the lighting load should not be less than 60kW per kilometer of tunnel extension. Taking the ...

Problems solved by technology

However, due to the low illumination and contrast in the tunnel, it is difficult for the driver to find the ordinary traffic engineering facilities in the tunnel, and the accident data also shows that their effect is limited

At the same time, the existing tunnel lighting mainly focuses on tunnel lighting energy-saving control, intelligent lighting control system, tunnel lighting settings combining natural light and artificial light, etc., and less research is based on traffic accidents, which also leads to high setup and operating costs. Traffic safety and benefits Mismatch

At the same time, the existing speed perception improvement method based on visual optical flow rate lacks research on the sense of direction and distance, which also leads to a decrease in sensitivity, reduced speed control effect, and even retaliatory acceleration after the driver is familiar with local information.
