Most commuter trains in large cities of Japan are loaded to their full capacity in the morning rushhours. Accordingly, it takes time for the many passenngers to get on and off at the major stations where many people come in and out, and the trains are often delayed. Although the construction and performance of the commuter train doors is considered to have a great influence on the ease of getting on and off, a method quantitatively evaluating the relation between them has not yet been established. The authors proposeda new method for evaluating the above relation, and obtained a satisfactory result through practical application of the method.
