And the traffic service for private cars，is not satisfactory in transportation to children，students，senior citizens，handicapped persons and people who do not have their private cars or driver's license. The aim of this paper is to evaluate the service level of public transportation in Itsukaichi district of Hiroshima City，which is commuter town. We evaluated the service level of public transportation in Itsukaichi district the sight and quantitatively by using Arc View GIS and the model of an existing research，by the over all index that contains fare，time，frequency，transfer resistance and punctuality，in consideration of the performance of total as “Movement” including not only traffic performance but also on foot.
