Abstract
Community bus called “YuYu Bus” is operated in Kumamoto city, to support trip convenience improvement of public transport. It is served on public transport inconvenience area which is 500m ~ 1,000m away from a station and a bus stop, and the area with few demands. Therefore income and expenditure rates are low and it is difficult to continue service. Hence, there is a service continuation criterion of 30% of income and expenditure rates. The bus service is abolished if inhabitants of the bus route cannot achieve these criteria.
In this study, we develop a travel demand model for community service which consists not only of trip frequency model representing the composition concept of ICF but also of individual mode choice model with consideration of social interactions. Using these models, we predict demands for community bus, and calculate income and expenditure rates. Also, we analyze relations between a route service levels and some environmental conditions which is needed to achieve a service continuation criteria.
