This paper is concerned with the problem on the regional pattern of urban traffic within Tokyo. With regard to this problem; considerable studies have been approached from a quantitative viewpoit, but urban structure seems to have been discussed separately. Thus, the author attempts to clarify the regional pattern of urban traffic from both qualitative and quantitative viewpoits and the relationships between urban traffic and urban structure. More precisely, the purposes of this reports are to clarify the regional of the gene-rated trips from both quantitative viewpoits, the relationships of the trips with population and land uses, and the directions of trips.<br> A survey was conducted in the following method: first, a questionnaire (Tab. 1) was prepared in order to search for the actual condition of urban traffic from a qualitative viewpoit; second, eighty-five primary school districts in Tokyo were selected by using the results of the preliminary survey in Shimoda, Shizuoka Pref.; third, fifty questionnaires were distributed to each district by the author.<br> As a result of analyzing the imformation which was collected from the questionnaires, the following points were made clear:<br> (1) Number of the generated trips in each district is closely related to the number of inhabitants in the district. The number of generated trips per inhabitant is smallest in the central part of Tokyo, and becomes greater toward peripheries. This difference is primarily due to the difference in the number of generated trips by persons without a job.<br> (2) In regard to the kind of trip purposes, persons with a job chiefly travel for commuting or working, while persons without a job chiefly travel for attending school or shopping. In residential areas trips for attending school, commuting and shopping are mostly generated, while in business, shopping and industrial areas those for working are generated for a most part.<br> (3) Destination distance of trips for attending school is short, and is longer as the trip person becomes a middle school pupil, a high school student, and a university student in turn. Destination distance of trips for commuting is the longest of all trips. Most of these trips in all districts are directed to the central part of Tokyo, but in eastern areas these trips to the central part are few and there may be a commuting area without strong connection with Tokyo's center. Destination distance of trips for shopping is the short-est of all trips and most of these trips are directed within the same district where they are generated. Trips for working are directed to two areas, that is, the same district where they are generated and the central area of Tokyo.
