A Two-Step Model for Predicting Travel Demand in Expanding Subways

In many cities, subways are expanding with new or extended lines being built and put into operations. The prediction of future travel demand in subway with the planned expansion is of significant importance because such information is crucial for new …

A coordinated model of bus bridging and passenger flow management and control in response to urban metro failure

Shuttle buses are generally sent to evacuate stranded passengers during urban metro disruptions. However, when a large number of passengers are transported to the turnaround stations by shuttle buses, it is likely to cause the passengers to wait for …

A Data-Driven Urban Metro Management Approach for Crowd Density Control

Large crowding events in big cities pose great challenges to local governments since crowd disasters may occur when crowd density exceeds the safety threshold. We develop an optimization model to generate the emergent train stop-skipping schemes …

Modeling real-time human mobility based on mobile phone and transportation data fusion

Faced with severe traffic congestions, the level of traffic planning and organization has been paid much attention. As a crucial and fundamental data for traffic planning and traffic organization, travel demand has been an important research topic …

Predicting subway passenger flows under different traffic conditions

Passenger flow prediction is important for the operation, management, efficiency, and reliability of urban rail transit (subway) system. Here, we employ the large-scale subway smartcard data of Shenzhen, a major city of China, to predict dynamical …

Understanding coupling dynamics of public transportation networks

Subway and bus networks work as an integrated multiplex transportation system and play an indispensable role in modern big cities. Even though a variety of works have investigated the coupling dynamics of multiplex transportation networks, empirical …

Vulnerability analysis of urban rail transit networks

The urban rail transit network is an important part of an urban public transportation system. First, we generated the network models of the urban rail networks of Beijing and Shenzhen. We used the subway smart card data to estimate the passenger …
