      城市道路交通安全评价体系研究与模型构建

      Model building and research of urban road traffic safety evaluation system

      摘要:
      城市交通的快速发展在给人们的工作和生活带来很大便利的同时也引发了一系列的交通问题,因此有必要对影响城市道路交通安全的因素进行研究,以建立一套能够合理准确对城市交通安全进行评价的体系和模型.文中首先在全面分析现有研究文献的基础上,将影响交通安全的因素归纳为四类,即人、车、道路及环境因素,深入分析了每个影响因素,利用层次分析法,依次选取相应的二级和三级评价指标,进而建立城市道路交通安全评价的综合体系;然后基于此评价体系利用模糊算法建立了城市交通状况的评价模型;最后利用建立的评价模型对5个城市进行评价,并与10位专家的评价结果进行比较,结果表明,新建立模型与专家的评价结果完全一致,可用于评价城市道路交通安全.
      Abstract:
      The fast-growing development of urban traffic gives great convenience to people, but also causes a series of traffic problems.Therefore, it is necessary to study factors that influence on urban road traffic safety, and to design a new traffic safety assessment method and model.First, basing on comprehensive analysis of previous studies, the factors are divided into four classes, including human, vehicle, road condition and environment factor.Then, basing on the analytic hierarchy process , second and third valuation index for each factor were chosen to establish the urban traffic safety evaluation system.Then, basing on fuzzy algorithmic, an evaluation model for urban traffic condition is designed.Finally, five cities` urban road traffic were evaluated using the evaluation system and model, and made a comparison of results from 10 experts.The comparison results show that new evaluation model is accuracy and practicability.This evaluation system can be used to evaluate urban road traffic safety.
