道路交通事故危险点鉴别的研究

Study on Discrimination of Traffic Accident Black Spot

对道路交通事故危险点的鉴别方法进行了综述,通过对比分析各种研究方法,提出了鉴别城市道路交通事故危险点的模糊评价法,并且对数学模型的描述、评价指标的选择以及隶属函数的确定这三个主要问题进行了研究.最后,利用模糊综合评价法对昆明市的9个交叉口的交通事故发生点进行了鉴别,其评价结果与公安交通管理部门提供的事故危险点鉴别结果一致,证明了该方法的有效性.

A summary is made of discriminating methods of black spots. Fuzzy evaluation is put forward by contrasting all kinds of the methods, and a study is made on the three main problems, such as the description of math model, choice of evaluation index and confirmation of subjection function. At last, 9 crosses of Kunming City are discriminated with fuzzy evaluation method, whose results are consistent with those provided by the public security and transportation administrative departments. The method is proven effective.
