摘要
为了客观反映道路安全等级的实际情况,建立改进的熵权—灰色关联—TOPSIS交通安全评价模型。该模型运用灰色系统理论,将影响交通安全的主要因素进行关联分析,同时采用熵权法确定指标权重,寻求最佳客观权重,并按照TOPSIS法计算出与理想方案的距离,衡量对该方案的满意度。最后选取四川省地级市道路交通事故数据为实际样本,验证了模型计算简便,结果合理,深入地挖掘出原始数据之间的内在规律。
In order to reflect the actual situation of road safety level,an improved entropy weight-gray correlation-TOPSIS traffic safety evaluation model was established.The model used the grey system theory to correlate the main factors affecting traffic safety,and used the entropy weight method to determine the index weights to seek the best objective weights and the ideal distance according to the TOPSIS method.Finally,the road traffic accident data of prefecture-level cities in Sichuan Province is selected as the actual sample.It has proved that the model is simple and the results are reasonable,and the inherent law of the original data is deeply explored.
