Abstract
Recently, excessive automobile dependence in local cities in Japan exemplifies the importance to compare the convenience between automobile and public transit. The purpose of this study is to develop a model that takes time of day into consideration in such a way to express bus travel time as a function of departure time. By using this concept, the regions where bus transit is equally competitive with automobile transportation were found based on the travel time standpoint. Moreover, comparing poorly-served area identified using the above model and public transport modal split, we would like to visualize the fluctuation of bus transit service area using GIS, and examine the relationship between bus transit service area and modal choice. In addition, the adaptability of this concept and model is discussed.
