Based on large-scale human mobility data collected in San Francisco and Boston, the morning peak urban rail transit (URT) ODs (origin-destination matrix) were estimated and the most vulnerable URT segments, those capable of causing the largest service interruptions, were identified. In both URT networks, a few highly vulnerable segments were observed. For this small group of vital segments, the...

July-August 2012 Imagine you fly home from vacation with your one-and-ahalf-year-old son who is traveling for free as a “lap child.” In the airport parking lot, you put him into his forwardfacing car seat, where he sits much more contentedly than he did in the rear-facing one that was mandatory until his first birthday. After he falls asleep on the way home, you transfer him to his crib without...

This research is based on the teaching practice process of urban rail transit operation management major in higher vocational colleges. Taking course Urban Rail Transit Ticketing Management as an example, focusing three links before class, during class and after this explores curriculum ideological political implementation plan from seven stages objectives, content, situation creation, independ...

The Urban Rail Transit (URT) has been one of the major trip modes in cities worldwide. As the passengers arrive at variable rates in different time slots, e.g., rush and non-rush hours, the departure frequency at a site directly relates to perceived service quality of passengers; the high departure frequency, however, incurs more operation cost to URT. Therefore, a tradeoff between the interest...

SimMETRO is a microscopic, dynamic, stochastic simulator of urban rail operations (METRO), specifically designed for service performance analysis, and evaluation of operations and strategies for real time control of subway systems. SimMETRO employs a detailed representation of the network, rolling stock, signal control, demand, schedule and dispatching. In particular, the various sources of sto...

An efficient public transport is more than ever a crucial factor when it comes to the quality of life and competitiveness of many cities and regions in Asia. In recent years, the rail-based urban mass transit has been regarded as one of the key means to overcoming the great challenges in Chinese megacities. The purpose of this study is going to develop a coherent network optimizing for railbase...

This article aims at identifying some commonalities and differences in intermodal freight in France and Japan, focusing on urban zones. This comparison puts into perspective two spatial situations tinged with land pressure. It helps us identify opportunities for knowledge and transfer of best practices for the promotion of modal shift and for land use and planning policies that favor intermodal...

The centuries since the birth of the Industrial Revolution have seen a succession of increasingly sophisticated transport technologies, each offering improvements in speed, carrying capacity and/or operational flexibility. Having spent this time overcoming the physical barriers to freedom of movement imposed on us by the natural world, humanity now appears to face two immense, and related, chal...

In the context of public transportation system, improving the service quality and robustness through minimizing the average passengers waiting time is a real challenge. This study provides robust stochastic programming models for train timetabling problem in urban rail transit systems. The objective is minimization of the weighted summation of the expected cost of passenger waiting time, its va...

High-speed became a fundamental political issue in Valencia, but also a major factor in regional planning and economic attractiveness and reactivated Valencia Parque Central project, which aim is to transform disused railways into a park and to build a station and its tracks underground. This new centrality should become the focal point of the whole urban and regional transport network. The new...
