| 摘 要： | 在进行城市交通规划时,交通分配是一个关键步骤,有效路径集合的确定对随机交通分配的结果有很大影响.本文首先对基于Logit的主要交通分配算法进行了分析,指出了它们的不足；通过分析可知,有效路径集合的定义应考虑路径本身的性质及交通需求量的大小,然后根据一条路径对其它路径分配到交通流量的影响程度给出了路径影响度的定义,并依据...

| Abstract: | Traffic assignment is a key step of urban traffic planning,and efficient path set significantly affects stochastic user equilibrium(SUE) traffic assignment.Thereby,the main allocation algorithms of the Logit model are analyzed and some disadvantages of them are point out.The conception of efficient path set should consider the path's character and traffic demand.Thus,the conception of path effect degree is defined according to the degree of one path affecting traffic volumes on other paths,and the conceptio... |
