Based on high-speed rail (HSR) network data from 2008 to 2020, this study explores the structural characteristics and evolution of China’s HSR perspective overall urban node centrality. We show that connectivity has improved significantly, whereas accessibility slightly. Furthermore, both density in different regions gradually a decreasing trend east coast zone southwest. also find centrality, ...

High-speed railway (HSR) station areas are expected to benefit urban environments, not simply as transportation or economic hubs but also places contributing living quality. However, the relationship between HSR and place quality has received systematic attention, despite evolution of planning paradigms toward a clearer focus on life. We have reviewed 44 academic articles written 1996 2019 anal...

The interest in the socioeconomic impact assessments of high-speed rail (HSR) system is burgeoning as many countries are considering investing such a system. While extensive studies have provided wide range evaluations HSR on impact, primarily from an ex-post perspective, it remains unclear how reliable evaluation outcomes were, given variety data, method and research framework being adopted. T...

The widespread high-speed rail has become an important transportation mode for tourists in China, who travel primarily in groups. With more attractive price, railway operators may be able to expand ridership, improve customer satisfaction, and ultimately increase revenue. The traditional pricing method for passenger groups, however, is relatively simple, inflexible, which may lead to profit los...

Very high speed rail may be a competitive mode of transportation for California's future. This article presents an evaluation of the economic and comprehensive benefits and costs associated with such an endeavor. The results indicate competitive comprehensive rates of return and a potential for project self-financing, suggesting that such a project merits serious consideration by the State.

High speed rail is a good example of a complex social-technical system, it combines high technology with social institutions to provide transport service. However, in spite of advances in HSR technology, HSR service is operated in much the same manner as traditional passenger rail service – an unsuccessful long-term business model. This research argues that HSR needs disruptive innovation to cr...

This article reviews some new ultrasonic rail inspection methods emerging in recent years. It focuses on the state of the art for guided wave technologies and their potential use for used for rail inspection. It considers ultrasound transduction options including EMATs, air coupled, pulsed laser and wheel probe guided wave methods. It compares performances in terms of frequency ranges, energy d...
