Study on different solutions to reduce the dynamic impacts in transition zones for high-speed rail

One of the most important factors influencing the track maintenance is the transitions between parts of the track with different vertical stiffness. The dynamic...

High Speed Rail Transport Valuation and Conjuncture Shocks

In the present paper we derive the optimal investment policy of investment in the high speed rail (HSR) project, under uncertainty, using the real options analysis (ROA) framework. We assume that the HSR demand, the main source of uncertainty, follows a geometric brownian motion with random jumps, complying with abrupt change of level caused by random events. The occurrence of such events is ca...

Life cycle assessment of High Speed Rail in China

China has built the world’s largest High Speed Rail (HSR) network. Its environmental impacts have been examined by the means of life cycle assessment (LCA) which describes the whole picture of the HSR system instead of single stages, with a case study for the highspeed railway that links Beijing and Shanghai. The research employs the China-specific life cycle inventory database Chinese Core Lif...
