Abstract

In order to improve safety, platform doors have been installed in some train and subway stations in the Tokyo metropolitan area of Japan. The number of accidents (such as passengers falling from platforms, or coming into contact with moving trains) has decreased. On the other hand, scheduled dwell times have had to be increased to allow for the extra time needed for platform doors to open and close. As such, travel times are longer after the installation of platform doors than before. However, an overall improvement in the stability of train operations has been observed during rush hour. This paper presents an analysis of such phenomenon and valuates the train operation stability.
