路的因素造成交通事故。对于高速公路来说，其本身的修建要特别注意道路的线

Road traffic accidents caused by factors. For highways, the construction of its own to pay special attention to construction of roads and road alignment. For highway road curvature, the radius must be reasonable control. At the same time, but also to strengthen the management and control of linear distance, longitudinal slope and the line of sight. Only control of their own situation highway from the road line and two aspects of the road, to be able to reduce road accidents because of factors caused.

Road factors cause traffic accidents. For highways, their own construction should pay special attention to the linear shape of the road and the structure of the road. For the highway road curvature, the radius must be reasonably controlled. At the same time, we should also strengthen the management and control of straight-line distance, slope and line-of-sight. Only by controlling the highway's own situation from the aspects of road linearity and road surface can the traffic accidents caused by road factors be reduced.

Road causes traffic accidents. For the expressway, its construction should pay special attention to the road alignment and road structure. For the curvature of highway, the radius must be controlled reasonably. At the same time, we should strengthen the management and control of line distance, longitudinal slope and sight distance. Only by controlling the situation of Expressway itself from two aspects of road linearity and road surface, can the traffic accidents caused by road factors be reduced.
