摘要通过对多项Logit(MNL)模型和两种路径大小Logit(PSL)模型的比较，评估了路径重叠特征对随机分配悖论的影响。研究了两种情况：(1)改进现有链路和(2)添加/删除新链路。在四个具有路径重叠连接的网络中，用数学和图形的方式说明和比较了三种模型的矛盾特征：(1)具有四个链接的单一始发地-目的地(O-D)对网络；(2)具有五个链接的单个O-D对网络；(3)具有七个链接的多个O-D对网络；(4)在哈尔滨市一个道路子网络中的应用。这些结论对交通规划、管理和控制政策/措施的评价具有重要的参考价值。
ABSTRACT This paper evaluates how the route overlapping feature affects the stochastic assignment paradox by comparing the multinomial logit (MNL) model and two path-size logit (PSL) models. Two circumstances, (1) improving an existing link and (2) adding/removing a new link, are studied. The paradoxical features of three models are illustrated and compared mathematically and graphically in four networks with route overlapping links: (1) a single origin-destination (O-D) pair network with four links; (2) a single O-D pair network with five links; (3) a multiple O-D pair network with seven links; and (4) an application in a road sub-network of Harbin City. The general conclusions are significant for traffic planners and engineers when those kinds of route choice models are used to evaluate traffic planning, management, and control policies/measures.
