Progress of research on evaluation indicators and standards about high-speed train comfort

Abstract

The rapid development of high-speed railway in China has proposed higher requests for the comfort level of high-speed trains. However, there is no internationally unified evaluation criterion for high-speed train comfort currently, which therefore substantially affects the comparability and standardization of research results for high-speed train comfort. This paper systematically reviews the research literature about evaluation indicators and standards related to high-speed train comfort, and finds that there is currently no unified definition, evaluation indicators, as well as evaluation criterion for high-speed train comfort. Most current evaluation criteria are based on a single indicator. Some indicators are simultaneously developed by different apartments and differ between each other, and there is no comprehensive indicator or criteria for high-speed train comfort, restricting the comparison of high-speed train comfort across regions. It is recommended that the administrative department of high-speed railroad in China should organize experts to establish a unified definition of high-speed train comfort, comprehensive evaluation indicators and relevant judgment criteria for high-speed train comfort, in face of the rapid development and globalization of high-speed trains.
