Application of Set-Valued Statistics in the Qualitative Evaluation of Road Safety of Mountainous Region

摘要：

Aiming at the complexity and the diversity of factors that have the influence on road traffic safety of mountainous region, and the fuzzy characteristic of influence of each factor. Set-Valued Statistics is presented to determine quantitative values of qualitative indexes that affect the traffic safety of roads in mountainous region, in order that resolves the problems which subjective judgments used in the grade proportion method and the experts evaluation method are difficult to be exactly expressed.
