摘要:

地铁系统在城市公共交通网络中扮演着越来越重要的角色,每天在城市中传递着大量的跨空间人流。近年来,为提高地铁系统的服务质量进行了广泛的研究。其中,人群管理一直是公共交通机构和训练运营商的关键问题。本文提出了一种利用累积的灵巧卡数据预测现场客流密度的统计模型,在封闭的地铁系统内,任何两个相邻车站之间的乘客数量。该模型主要完成两个任务:(1)应用成熟的统计模型预测时间依赖的OD矩阵;(2)利用截断正态混合分布和EM算法估计地铁网络不同部分所需的旅行时间成本。根据预测结果,我们能够提供准确的预测现场的乘客密度为未来的时间点。一个案例研究,使用真实的灵巧卡数据在新加坡大众快速交通(MRT)系统证明了我们所提出的方法的有效性和效率。

英文摘要:

The metro system is playing an increasingly important role in the urban public transit network, transferring a massive human flow across space everyday in the city. In recent years, extensive research studies have been conducted to improve the service quality of metro systems. Among them, crowd management has been a critical issue for both public transport agencies and train operators. In this paper, by utilizing accumulated smart card data, we propose a statistical model to predict in-situ passenger density, i.e., number of on-board passengers between any two neighbouring stations, inside a closed metro system. The proposed model performs two main tasks: i) forecasting time-dependent Origin-Destination (OD) matrix by applying mature statistical models; and ii) estimating the travel time cost required by different parts of the metro network via truncated normal mixture distributions with Expectation-Maximization (EM) algorithm. Based on the prediction results, we are able to provide accurate prediction of in-situ passenger density for a future time point. A case study using real smart card data in Singapore Mass Rapid Transit (MRT) system demonstrate the efficacy and efficiency of our proposed method.
