摘要
Highway safety is one of the targets of the road design, coordination of highway design index and the actual vehicle speed is the key. According to the analysis of automobile speed observation data, established the plain or hilly area two road car model, put forward highway alignment design safety evaluation standards and safety design method. Traditional highway alignment design method which base on design speed, had materially stipulated lowest design standard that the satisfied design vehicle speed must achieve, but to using high the linear target has not limited, caused the single linear target to satisfy the request, but many targets combined not necessarily are reasonable linear. In the path actual operation, the actual performance speed of vehicles normally must be higher than the design speed, causes the running rate and linear target of vehicles comes apart, in the linear bad road section, is extremely easy to have the high vehicle speed and low linear contradiction, forms the accident "black-spots", poses the serious threat to the traffic safety([1-5]).
