Since many people have to be carried to the event venue, it is necessary that transportation is planned in consideration of traffic influence and management of time schedule. In this paper, through traffic simulation, transit plan by using scheduled buses is tested. Keywords: multiagent system, traffic simulation, transportation planning Introduction In this paper, we try to show possibility of utilizing traffic simulation to evaluate transportation plan for big events by exhaustive framework of large-scale simulation. In a big event, design of transportation plan is a critical issue for smooth and feasible oper- ation of the event. Especially, when the event is held inside of city area, the design is so difficult because the background traffics are varied by situations and also affected by trans- portation for the event.
