ABSTRACT

Interchange provides more flexibility in route choice, a key travel behaviour in urban rail transit, but its influence is usually simplified. This paper investigates how interchange affects route choice with passenger perception considered. At single-interchange level, perceived interchange time was proposed and modelled under three resolutions to capture passenger perception and its sensitivity. At route level, the influence of interchange was modeled by first comparing eight quantifications of interchange. Mixed logit models with the best interchange proxy were further developed to address the correlation among alternative routes and reveal the potential taste variations among passengers. Results based on Shanghai Metro data showed perceived interchange time, including passenger perception and interchange environment, better represents the influence of interchange in route choice, meanwhile the weights of interchanges on one route rise sequentially and non-linearly. The results can improve route choice prediction in demand modelling and route recommendation in advanced traveller information systems.

摘要

立交在路线选择上提供了更大的灵活性，这是城市轨道交通的一个关键出行行为，但其影响通常被简化。本文在考虑乘客感知的情况下研究了换乘如何影响路线选择。在单换乘水平上，提出了感知换乘时间并在三个分辨率下建模，以捕捉乘客感知及其敏感性。在路线层面，通过首先比较交换的八种量化来模拟交换的影响。进一步开发了具有最佳换乘代理的混合 logit 模型，以解决替代路线之间的相关性并揭示乘客之间潜在的口味变化。基于上海地铁数据的结果显示了感知换乘时间，包括乘客感知和换乘环境，更好地代表了立交对路线选择的影响，同时一条路线上的立交权重呈顺序非线性上升。结果可以改进高级旅行者信息系统中需求建模和路线推荐中的路线选择预测。
