 note = {application, It is important to offer the high bus service of the level in order to improve the mobility in a center business area. In other words, it is necessary to decide service level of buses where are run according to the traffic demand. Each item that the circular route, that is the bus line, the interval of bus stops, the running interval time are defined for that needs to be optimized. In this study, we propose a deciding system of circular bus route in considering the trade off between the running cost and user cost. The application of this system is confirmed by using the actual road network in Nagano city.},
