    摘要:

    引入可变模糊理论中的相对差异函数,建立高速公路隧道群交通安全评价模型.根据相关研究成果,选取影响高速公路隧道群交通安全的主要因素构建安全评价指标体系.综合层次分析法(AHP)和信息熵法确定评价指标的权重,建立相对差异函数安全评价模型.利用相对差异函数评价模型对隧道群交通安全等级进行判别,得出评价结果.将该方法应用于浙江省某高速公路隧道群交通安全评价,针对评价结果提出隧道群安全改善对策,并将该方法与其他交通安全评价方法计算结果进行对比,结果表明该模型在高速公路隧道群交通安全评价应用中有较好的实用性.

    Abstract:

    relative different function of the variable fuzzy theory was introduced to the building of a safety assessment model for tunnel groups. Based on the previous researches, the main factors influencing the tunnel group traffic safety were chosen to construct an evaluation index system, and then, the weights of the evaluation indexes were obtained on the basis of the results by analytic hierarchy process (AHP) method and the entropy of information. Subsequently, a relative different function assessment model was adopted to evaluate the tunnel group traffic safety level. Finally, the safety level of a mountainous freeway tunnel group in Zhejiang Province was evaluated with the proposed model, and some safety improvement measures were proposed accordingly. A comparative study of the analytical results show this model is effective in traffic safety assessment for tunnel groups on freeways.
