Abstract
This paper focuses on Typhoon Roke (2011) which caused severe damage in Tokai region, and investigates that the effect of the typhoon on public transport. The relationship between public transportation user's behavior and the train service information was analyzed. The return-home behavior model and the travel time for return home model were developed. The result showed that the ratio of giving up to return home and the way of returning home is different because each train service's recovery is different, and the ratio of the commuters who got accurate information is less than half. In addition, commuters who didn't get the information tend to return home, and even the commuters who got the information, return-home behavior and the degree of difficulty to return home is different because it is different that when and how they got information. For reducing the degree of difficulty to return home, it is important to provide accurate information rapidly.
