It is very important to have enough sight distance to ensure drivers drive safely on the road. Enough sight distance will give the driver enough time to judge the changes of road's direction and gradient accurately and then choose the correct driving line to avoid hitting rolling stocks and roadblocks or park the vehicle down on the emergency parking places at state of emergency. Based on the principle of the vertical curve design, this paper discusses the safe driving conditions on highways and doing research on the impacts of road sight distance. Combined with safety evaluation for one expressway, this paper proposes some reasonable recommendations for black spot treatment.
