随机路径选择 meaning in English

random routing

The author discussed the four steps model and provided the ameliorative method of the logit model and the solution of the fictitious public traffic routes . firstly , the author discussed the result of survey of residents trip , concluded the primary character of residents trip and put forward the method of stratified random sampling plan on that .
预测时采用了一种比较流行的“四阶段模型法” ，针对“四阶段模型法”的出行分布、交通分配子系统展开了深入的讨论，提出了针对重庆山城交通特点的“改进的logit型的随机路径选择模型”和“虚拟公交线路算法” 。
Secondly , because the logit model applied to the traffic assignment is only suit to the problem of the trip cost independent of the number of passengers on the route and the stochastic user equilibrium model is abstruse and complex in solution , the author brought forward the ameliorative method of the logit model
其次，在交通分配子系统中，由于logit型的随机路径选择模型只适用于路径的实际出行成本与路径流量无关的交通分配问题，而随机均衡配流模型( stochasticuserequilibrium ， sue )虽然考虑了路径流量，但算法复杂，难于推广。
