document: Recent researches of human science on railway systems This paper presents research of human science on railway systems at RTRI . They are roughly divided into two categories : research to improve safety and those to improve comfort . On the former subject , for the safeguard against accidents caused by human errors , we have promoted studies of psychological aptitude test , various research to evaluate train drivers ' working conditions and environments , and new investigations to minimize the risk of passenger casualties at train accidents .
