The purpose of this study is to verify whether locating community facilities intensively is really effective or not. Many planned residential areas have neighborhood centers where community facilities are located intensively so that the total travel distance of users is minimized. However, there is a doubt whether such centers can satisfy the facility location that accords with use frequencies of each user. To answer this question, this study developed a computer simulation system that forms two and three dimensional urban space with the most suitable location of facilities and houses that accords with use frequencies of each user.
