Transportation by train has numerous advantages over road transportation, especially with regard to energy efficiency, ecological features, safety, and punctuality. However, the contrast in ride comfort between standard road transportation and train travel has become a competitive issue. The ride comfort enhancement technology of tilting trains (TTX) is a particularly important issue in the development of the Korean high-speed railroad business. Ride comfort is now defined in international standards such as UIC13 and ISO2631. The Korean standards such as KSR9216 mainly address physical parameters such as vibration and noise. In the area of ride comfort, living quality parameter techniques have recently been considered in Korea, Japan, and Europe. This study introduces biological parameters, particularly variations in heart rate, as a more direct measure of comfort. Biological parameters are based on physiological responses rather than on purely external mechanical parameters. Variability of heart rate and other physiological parameters of passengers are measured in a simulation involving changes in the tilting angle of the TTX. This research is a preliminary study for the implementation of an e-health train, which would provide passengers with optimized ride comfort. The e-health train would also provide feedback on altered ride comfort situations that can improve a passenger's experience and provide a healthcare service on the train. The aim of this research was to develop a ride comfort evaluation system for the railway industry, the automobile industry, and the air industry. The degree of tilt correlated with heart rate, fatigue, and unrelieved alertness.
与公路运输相比，火车运输具有许多优势，尤其是在能源效率、生态特征、安全性和准时性方面。然而，标准公路运输和火车旅行之间的乘坐舒适性差异已成为一个竞争问题。摆式列车（TTX）的乘坐舒适性提升技术是韩国高铁业务发展的一个特别重要的问题。乘坐舒适性在 UIC13 和 ISO2631 等国际标准中进行了定义。韩国的 KSR9216 等标准主要涉及振动和噪声等物理参数。在乘坐舒适性领域，韩国、日本和欧洲最近考虑采用生活质量参数技术。本研究引入了生物参数，特别是心率变化，作为更直接的舒适度衡量标准。生物参数基于生理反应，而不是纯粹的外部机械参数。在 TTX 倾斜角度变化的模拟中，测量了乘客心率和其他生理参数的变化。这项研究是实施电子健康列车的初步研究，它将为乘客提供优化的乘坐舒适性。电子健康列车还将提供有关乘坐舒适性变化的反馈，这些变化可以改善乘客的体验并提供列车上的医疗服务。本研究旨在为铁路、汽车和航空工业开发乘坐舒适性评估系统。倾斜度与心率、疲劳和警觉性降低相关。
