Application of Grade Analysis Method on Road Safety Evaluation

Owing to diverse, fuzzy and random characteristics of road influence factors on traffic safety, grade analysis method of fuzzy set theory is applied to evaluate road safety, which could overcome the issues that hard objective and effective mathematical evaluation method determination and low - grade subjective evaluation precision. Aiming at safety evaluation on complex roads that have multi - criterions and multi - hierarchy characteristic, safety evaluation conclusions are elicited and main road causal factors are determined by a synthetic method combined grade analysis with multi - criterions safety integrated evaluation method.
