Summary
Tilting trains (TTX) can enhance passenger comfort by adjusting tilt angles. This study measured heart rate variations to directly assess ride comfort, paving the way for advanced e-health train services.
Area of Science:
- Transportation Engineering
- Biomedical Engineering
- Human Factors Engineering
Background:
- Train travel offers advantages in efficiency, ecology, safety, and punctuality over road transport.
- Ride comfort is a critical competitive factor, especially for Korean high-speed rail development involving tilting trains (TTX).
- Current ride comfort standards focus on physical parameters like vibration and noise, but living quality and biological parameters are gaining importance.
Purpose of the Study:
- To introduce biological parameters, specifically heart rate variability, as a direct measure of passenger ride comfort in tilting trains.
- To develop a novel ride comfort evaluation system applicable to railway, automobile, and air transport industries.
- To lay the groundwork for an e-health train concept offering optimized comfort and healthcare services.
Main Methods:
- Simulated changes in the tilting angle of tilting trains (TTX) were used to measure passenger physiological responses.
- Variations in heart rate and other physiological parameters were recorded during the simulation.
- The study correlated the degree of train tilt with passenger heart rate, fatigue, and alertness levels.
Main Results:
- A correlation was found between the degree of tilt in tilting trains (TTX) and measurable changes in passengers' heart rate.
- Passenger heart rate variability and alertness levels were identified as key indicators of ride comfort.
- The findings suggest that biological parameters offer a more direct assessment of comfort than traditional physical metrics.
Conclusions:
- Heart rate variability serves as a direct and effective measure for evaluating ride comfort in tilting trains.
- This research supports the development of advanced ride comfort systems and the concept of an e-health train.
- The developed evaluation system has potential applications across multiple transportation sectors, including rail, automotive, and aviation.
