Although the Japanese accessibility guidelines for public transport currently give no numerical criteria of luminance contrast around TWSIs, it may not be long before the guidelines introduce such criteria. This means that practical methods to measure luminance contrast around TWSIs will be required in stations in the near future. Preparing for it, we developed a manual on measuring methods of luminance contrast around TWSIs, taking environmental characteristics of stations into consideration. This paper reports the process of our making of the manual.

However, the actual situation is not clarified because it is hardly investigated the ride comfort about the vertical curve passage until now. Therefore, two kinds of subject experiments by the high-speed train were carried out to obtain the knowledge of the ride comfort in the vertical curve passage, and the following results were provided. It was suggested that not only the acceleration but also the jerk influenced the perception of the vertical curve. In the same condition as the passengers of the operating train, the perception ratios of the vertical curve were about 60 % at maximum speed 275 km/h, and about 70 % at that 320 km/h. In the vibration ride comfort of including the vertical curve, the railroad employees were strictly evaluated than general subjects, and young group subjects were strictly estimated than elder ones.
