Abstract
The objective of this paper is to study on bus operation as substitute for urban railway after big earthquake in the Tokyo metropolitan area. Firstly, the facilities that can be a candidate for the bus yard were extracted using google map and street view function. Secondly, transportation capacity in the case of operating the substitute bus in two sections was estimated and sensitivity analysis on the impact factors on transportation capacity was performed. The results of this study showed that ring route is more effective than radial route, and travel distance and scheduled speed have influence to transportation capacity.
