论文摘要
经常使用计算密集的微观模型来对城市地区的行人交通进行估计，这些模型通常会遇到大规模的人行道网络中的可伸缩性问题。在这项研究中，我们提出了一个新的宏观用户平衡交通分配问题（UE-PTAP）框架，同时考虑到基本的显微镜特性，例如双向流中的自组织和随机步行旅行时间。我们提出了四种不同类型的行人音量延迟功能（PVDF），用经验数据对其进行校准，并讨论它们对交通分配解决方案的存在和唯一性的影响。我们证明了开发的UE-PTAP框架在小型网络以及悉尼人行道的大型网络中的适用性。
The estimation of pedestrian traffic in urban areas is often performed with computationally intensive microscopic models that usually suffer from scalability issues in large-scale footpath networks. In this study, we present a new macroscopic user equilibrium traffic assignment problem (UE-pTAP) framework for pedestrian networks while taking into account fundamental microscopic properties such as self-organization in bidirectional streams and stochastic walking travel times. We propose four different types of pedestrian volume-delay functions (pVDFs), calibrate them with empirical data, and discuss their implications on the existence and uniqueness of the traffic assignment solution. We demonstrate the applicability of the developed UE-pTAP framework in a small network as well as a large scale network of Sydney footpaths.
