Influence Of Mountainous Road Alignment On Traffic Safety And Reconstruction Measures

This paper has roundly and systematically researched on the traffic crashes of certain westward mountainous road. Through the analyzing of crash general characters and auditing the influence to traffic safety of the road plain, profile and their combination, some hidden troubles of the road and relevant reconstructed measures would be found. The conclusion shows that the ill alignment (a lot of limit guidelines on design and continuous long downgrades) is the main reason of inducing traffic crashes on mountainous road, which let the hidden troubles especially high. Aim at the crashes reasons, this paper puts to setting up reducing temperature devices and escaping ramp to solve the downgrade crashes, which also can make up the defects on alignment design. What's more, other measures such as speed control devices also can warn and restrict drivers to reduce the probability of crashes either. For the covering abstract see ITRD E138091.
