| With the development of the transportation, China has become the world’s largest, most complex tunnel, the fast developing countries. Highway tunnel as the bottleneck of expressway network, with easy traffic accidents, characteristics and major accident hazard degree, post processing difficulties. Through the analysis of the characteristics and causes of traffic accidents on expressway tunnel, the tunnel of expressway traffic accidents and tunnel sections visual environment and the driver, and the driver mainly relies on the visual system to obtain various traffic information, therefore, study on the driver’s visual environment in the tunnel section characteristics and visual environment protection technology to improve the operation safety of the tunnel is very important significance.In this paper, through the analysis of traffic accident data of relying engineering--tunnel red wood, distribution features of vehicle distribution characteristics of traffic accident in tunnel sections, red wood species distribution characteristics and the time of the accident was obtained, and the quality control method of tunnel red wood’s accident-prone sections were identified, respectively from the aspects of people, vehicles, tunnel environment analysis of tunnel accident causes, and puts forward the countermeasures to improve the highway tunnel operation safety.Based on analysis of tunnel traffic environment and driver’s visual environment characteristic, elaborated the existing tunnel of physiological, psychological and influence of the driver’s vision. Research shows that, one of the important reasons for the tunnel entrance section speed too fast is caused by accidents, and inside the tunnel road illumination inadequate, uneven distribution, low visibility is a key factor behind the driver’s visual load is too large, so the speed control theory, lane keeping theory and inside the tunnel sections of the proposed highway tunnel the visual environment protection technology three aspects of the theory of inverse reflection technology theory.Combining with the project--Muchong tunnel traffic environment and visual environment characteristics, determine the wood rush tunnel section, speed control scheme of edge lane keeping technical scheme and retroreflective contour standard application technology scheme, and analyzes its social benefit and economic benefit, provide a reference for other domestic highway tunnel operation safety. |
