基于集对分析的平面交叉口安全性评价

Safety Evaluation of Intersection Based on SPA

针对传统交叉口安全性评价方法中存在的主观不确定性,利用集对分析理论对指标权重矩阵集对处理,减少或消除其主观影响,并根据已有交叉口安全性评价指标研究成果,建立平面交叉口安全性评价的集对分析模型,利用同一度和差异度大小确定交叉口安全归属,形成了交叉口安全性评价的新方法.并通过实例分析验证了该模型的可行性.研究表明,集对分析模型应用于交叉口安全性评价有一定的可行性和实用性.

With consideration of the uncertainty problem of traditional method of intersection safety evaluation,the paper removes the effect of subjective factors by dealing with index matrix by SPA.According to existing research results of intersection safety evaluation,SPA analysis model is established.A new method for Safety evaluation of intersection is presented.And the feasibility of the model is proven through the actual data.It has been shown that the evaluation model based on SPA is feasible and valuable.
