摘　　要：针对雨雾天气下的动态交通路径问题,分析了能见度影响因子,研究了基于AASHTO停车视距模型的安全车速,进行了顾及能见度影响因子的综合安全车速计算。在此基础上进行了动态交通网络中的成本路径分析,探讨了能见度影响因子对距离成本、时间成本和运输成本等路径分析的影响。实验结果表明,该模型对于动态交通路径研究,具有较强的可行性和实用性。In order to solve the dynamic traffic routing problem in foggy weather environment, the visibility influential factors were researched, the safe driving speeds on the AASHTO model of stop sight distance were calculated. The safe driving speeds calculation values considering visibility influential factors was established, and an experiment on cost path analysis of dynamic traffic network was given. The influence of cost path analysis on the result of distance costs, time cost and transportation costs were analyzed. Experimental results showed that, for the research on dynamic traffic network, the proposed models presented more feasibility and practicality.
