摘要

在不受限制的交通条件下，路网中的某些信息会导致出行者在进行路线选择时产生反应延迟。因此，一些旅行者不得不在旅途中多次调整他们的路线选择。但现有的分配方法未能考虑到这一现象。本文分析了引起延迟响应(DRI)的信息的特征及其影响下的出行模式。为了定量地表示影响，将研究区域分层为各种规则或不规则的环，作为可能发生路线选择变化的子区域。并对OD对之间的交通量进行分段，以反映出行者在环线中调整路线选择的可能性。然后提出了一种改进的多路径流量分配方法，并对相关问题进行了讨论

A Refined Multi-path Traffic Assignment Method Considering Delayed Response

Under unrestricted traffic conditions, some information in the road network causes travelers have delayed response when making route choices. Consequently some travelers have to adjust their route choices more than once en route. But existing assignment methods failed to take into account this phenomenon. This paper analyzes the characteristics of the information causing delayed response (DRI) and the travel patterns under its influence. To quantitatively represent the influence, a study region is stratified to various regular or irregular rings as sub-areas where possible change in route choice may happen. And the traffic volume between an OD pair is segmented to reflect the possibilities of the travelers who adjust their route choices in the rings. Then a refined multi-path traffic assignment method is presented and some relevant issues are discussed as well
