A Subjective Evaluation System for High-Speed Trains Ride Comfort

There is no uniform ride comfort evaluation method of high-speed trains in current research. This study presented a model to evaluate subjective comfort depending on 6 influence factors of ride comfort. Based on NASA-TLX, a train ride comfort index was developed and used to collect data from participants. Weights of each factors and comfort scores were calculated by multi-dimensional overall comfort algorithm. Experimental results show that reliability and validity of the TRCX was acceptable, ensuring effective input variables of the model. Based on these findings, a subjective evaluation software system of trains ride comfort was developed to demonstrate the usability in practical application.
