基于熵权-TOPSIS模型的我国区域道路交通安全评价

Evaluation of Regional Highway Transportation Safety in China Based on Entropy-TOPSIS Model

为科学、有效地评价和改善我国省级区域道路交通安全水平,预防和减少交通事故的发生,合理选择了评价指标,构建了道路交通安全评价指标体系,应用熵权-TOPSIS评价模型,对我国31个省级区域(不含港、澳、台)的道路交通安全水平进行了综合评价与排序。结果表明:我国省级区域道路交通安全水平与地区生产总值、人口数量、机动化水平等社会经济因素具有较强的相关性,不同区域道路交通安全水平存在较大差异;基于熵权的TOPSIS模型操作简便易行,评价结果更加客观,其既可对多个区域进行对比评价,也可对某个特定区域进行单独评估,有助于及时发现相应的安全问题,从而为改善区域道路交通安全水平提供决策依据。

In this paper, we built a highway transportation safety evaluation index system, used the entropy-TOPSIS evaluation model to com- prehensively evaluate and rank the highway transportation safety level of the 31 province-level regions （ excluding Hongkong, Maeau and Taiwan ）, and found that the highway transportation safety level of the regions was significantly correlated with the GDP, population and motorization level of the regions and that the entropy-TOPSIS model was highly feasible and objective.
