摘要
为解决农村道路交通安全的评估问题,根据农村道路情况分析并提出一套完整全面的评估框架:构建农村道路交通安全指标体系,以熵权法确定指标权重,引入多目标决策技术中的协调分析法建立农村道路安全分析、评价与决策模型,并给出一个实例分析。通过灵敏度分析与实例结果对比,验证所提模型的有效性。研究结果表明:所提出的框架和方法能够很好解决农村道路交通安全评价问题。
In order to solve the problem of rural road traffic safety evaluation,a comprehensive evaluation framework was put forward according to analysis of rural roads situation.The index system of rural road safety was constructed and the weight was determined based on the entropy method.Among the different multicriteria techniques available,the Concordance Analysis was adopted here to eatablish the rural road safety analysis,evaluation and decision model.An example problem was also presented to illustrate the model.Through the comparison between the sensitivity analysis and results from example,the effectiveness of the proposed model was verified.The results show that the proposed framework and methods have good ability in safety evaluation for rural road traffic safety evaluation.
