多层Logit结构多模式变量需求网络平衡模型

探讨了多类别多模式变量需求网络平衡模型，模式选择模型采用多层ｌｏｇｉｔ结构，终点选择特定为一个多比例熵出行分配模型，公交车辆的出行时间与同一路网的其他车辆另行时间密切相关，采用变分不等式方法将模型的全部组元集合于一个模型中，并运用基于ＢｌｏｃｋＧａｕｓｓ－Ｓｅｉｄｅｌ分解算法有效地解决了固定需求和多维出行分布网络平衡模型的计算，论文给出了根据智利圣地亚哥市数据由ＥＭＭＥ／２软件包所得到的数值结果。

A MULTI-CLASS MULTI-MODE VARIABLE DEMAND NETWORK EQUILIBRIUM MODEL WITH HIERARCHICAL LOGIT STRUCTURES

We consider a multi -class multi -mode vahable demand network equilibrium model where the mode choice model is given by aggregate herarchical logit structures and the destination choice is specified as a multi - proportional entropy type trip distribution model. The travel time of tranait vehicles depends on the travel time of other vehicles using the road net-work. A variational inequality formulation captures all the model components in an integrated form. A solution algorithm, based on a Block Gauss-Seidel decomposition approach couoled with the method of successive averages results in an efficient algorithm which successively solves network equilibrium models with fixed demands and muti -dimensional the distribution models. Numehcal results obtained with an implementation of the model with the EMME/2software package are presented based on data originating trom the city of Santiago, Chile.
