Abstract
Traffic simulation system is one of the most effective methods to analysis micro-level traffic situation., In Japan, it is serious traffic problem that there are heavy traffic impacts because of on-street parking at the narrow road in the urban area. Authors developed the innovative micro traffic simulation system for personal computer named tiss-NET. The purpose of this study is to make traffic simulation system for traffic assessment through making car behavior models as on-street parking. By case study using tiss-NET, the quantitative effects of some types of provision of on-street parking were clear.
