Research has shown that traffic accident can be caused by the interaction of many factors. The high-grade highway landscape is one of the most significant factors impacting road safety. However, very few detailed studies are dedicated to this factor. In this paper, a synthetic evaluation method is proposed for the impact of high-grade highway landscape on road safety. This method combines qualitative and quantitative evaluation methods and takes full consideration of the features of local road landscape. The indexing factors included in this evaluation method are the environmental safety factors, the project safety factors and the human safety factors. First, qualitative evaluation is conducted by experts to evaluate the photographs and video records taken at different locations along the road. Second, the results of expert evaluation are quantified by fuzzy consistent matrix method. Finally, the synthetic evaluation model is constructed by applying weighed arithmetic average method on the qualitative and quantitative evaluation results. An index, namely Index of Relationship between Road Landscape and Safety (IRRLS), is calculated by the proposed model, and can be used to evaluate the impact of the full range highway landscape on road safety. This proposed evaluation method has been validated by a case study on An¡¯er Road in Jilin province of China.
