组合出行方式下的混合均衡分配模型及求解算法

MIXED EQUILIBRIUM MODEL AND SOLUTION ALGORITHM IN TRANSPORTATION NETWORKS WITH COMBINED MODE

在现代城市的出行活动中,人们往往需要换乘一种或多种交通工具才能到达目的地,这种出行方式称为组合出行方式．在组合出行方式下,人们除了选择路径,还要选择换乘站点．我们研究了组合出行方式下的混合均衡分配问题,提出了与均衡分配条件等价的变分不等式模型,设计了求解模型的算法,并用一个算例说明了模型和算法的有效性．

A lot of commuters in modern cities take their travels to reach destinations by using more than one mode. This commuting mode, called combined one, requires people to choose transfer points besides deciding routes. This paper deals with the mixed equilibrium model in networks with combined mode. The model is expressed by a variational inequality that can result in user equilibrium route choice and logit type mode and transfer point choices. An algorithm for solving the model is proposed and validated by a numerical example.
