Over the last few years, cities have made available large volumes of smart card data that shed light on the urban dynamics of transit users. This research uses metro card data from Shenzhen, China, to recognize individual mobility patterns and predict travelers' future movements. Joint entropy is proposed to measure the regularity of spatio-temporal patterns and travelers are divided into three groups, i.e. regular users, variable users and irregular users, based on the entropy value. Revised Markov ...

The development of transportation networks has constantly increased the cross-boundary flow of people, logistics, and capital. However, when the cross-boundary flows span two regions with different political systems, cross-boundary mobility studies become difficult to perform due to the unavailability of reliable and direct research data. Consequently, in-depth and fine-scale cross-boundary mobility studies remain lacking. With the aid of a smart card dataset, this paper proposes a new framework ...

Ridership analysis at the local level has a pivotal role in sustainable urban construction and transportation planning. In practice, urban rail transit (URT) ridership is affected by complex factors that vary across the urban area. The aim of this study is to model and explore the factors that impact metro station ridership in Shenzhen, China from a local perspective. The direct demand model, which uses ordinary least squares (OLS) estimation, is the most widely used method of ridership modeling. ...

Previous studies explore the impact of rail transit on land development and identify the size of its impact area. However, many pre-specify their relationship as linear or quadratic. This restrictive assumption biases the estimate for rail transit impact. To relax this assumption, this study employs gradient boosting decision trees to the 2008 and 2014 building census data in Shenzhen, China, and examines the nonlinear relationship between distance to metro stations and land development intensity, ...

Research has shown that the growing holiday travel demand in modern society has a significant influence on daily travel patterns.

This paper adopts a text-mining model (latent Dirichlet allocation (LDA)) to explore the travel patterns and travel purposes during the CSF season in Shenzhen ...

With the prosperous development of the urban metro network, the characteristics of the topological structure and node importance are changing dynamically. Most studies focus on static comparisons, and dynamic evolution research is rarely conducted. It is necessary to track the dynamic evolution mechanism of the metro network from the perspective of development.

In recent years, free-floating bike sharing (FFBS) has become an effective travel mode to connect the urban rail transit in the first/last mile. However, access duration, a significant factor for integrating bike and metro systems and improving the connecting efficiency, has received little attention from scholars. To fill this gap, the goal of this study is to identify the factors that affect the access duration of FFBS as a feeder mode to and from metro stations. Using operation data of FFBS in ...

The transit-oriented development literature has focused on the built environment around stations in operation, largely neglecting how the station location was selected. We hypothesize that city governments in China are likely to put stations outside established suburban centers. By putting metro stations at relatively underdeveloped places, city governments can lower right-of-way cost and gain more revenue from future land transactions. Using Shenzhen as a case study, we test this hypothesis with ...

Like many other transit modes, the metro provides stop-to-stop services rather than door-to-door services, so its use undeniably involves first- and last-mile issues. Understanding the determinants of the first- and last-mile mode choice is essential. Existing literature, however, mostly overlooks the mode choice effects of traffic safety perception and attitudes toward the mode. To this end, based on a face-to-face questionnaire survey in Shenzhen, China, this study uses the two-sample t-test to ...

We examine the air-quality effects of urban-rail development in Shenzhen, taking a difference-in-differences approach. This study is motivated by existing mixed evidence on the rail-pollution relationship, which we associate with the dynamic nature of the relationship itself. Our results demonstrate that the relationship varies by time, depending on network density and scale. New station openings had no significant impacts on local air quality or even worsened it until the 2010 metro-line extension, ...

Using metro smartcard data in Shenzhen, we develop a gradient boosting decision trees model to estimate the relative importance of land use variables and their threshold and moderating effects on ridership. We found that station betweenness centrality has the largest predictive power, followed by employment density and commercial floor area ratio (FAR). ...

Understanding the intertwined usages of these three transit modes at different places and time allows for better sensing of urban mobility and the built environment. In this article, we leverage a comprehensive data collection of bus, metro, and taxicab ridership from Shenzhen, China ...

Vibrancy is one of the most desirable outcomes of transit-oriented development (TOD). The vibrancy of a metro station area (MSA) depends partially on the MSA’s built-environment features. Predicting an MSA’s vibrancy with its built-environment features is of great interest to decision makers as these features are often modifiable by public interventions. However, little has been done on MSAs’ vibrancy in existing studies. On the one hand, seldom has the vibrancy of MSAs been explicitly explored, and ...
