Analysis of the Relationship between Urban Characters and Physical Activity Levels Based on the Travel Behavior Data

Abstract

It is well recognized the importance of physical activity such as walking for human health. This study aims to find the relationship between urban characters and physical activity levels in Japan, especially focusing on travel behavior. The authors analyzed it by using trip data in 40 cities from 1987 to 2005. According to their analysis, first, the authors showed the fundamental feature of physical activity in terms of travel mode and personal attributes. Second, it was found that physical activity levels of individuals had decreased by 20% during this period, and the result supported the idea that the urban density and also the car ownership levels in cities are related to the physical activity levels.?х젘令뜰겘?곩겈佯룔겏??뼟?ｃ걣?뉑몮?뺛굦?뗤벡?싪벴鵝볠뉵?뺡뇧??읃鹽롧쉪?ゅ궬?묆굮?곩닶?ⓧ벡?싨뎸餘듐굜?뗤볶掠욄 ㎯ 곥걬?됥겓??꺗躍귞돶?㎯겏??뼟?ｃ걢?됪삇?됥걢?ャ걲?뗣걼?곥 곫??앫겓??005亮닷츪?썬겗?ⓨ쎖?썲툊雅ㅹ 싩돶?㎬た?삠겗雅ㅹ 싪죱?뺛깈?쇈궭?믥뵪?꾠겍?곩 뗤볶??벡?싪벴鵝볠뉵?뺡뇧?ⓨ닶?ⓧ벡?싨뎸餘드룋?녑 뗤볶掠욄 ㎯겏??뼟?ｃ굮?녷옄?쀣걼?귝А?꾠겎??987亮담 ?992亮닷츪?썬겗?ⓨ쎖?썲툊?묆꺖?썬꺍?덀꺁?껁깤沃욘읅?믣뒥?덀걼3亮닸А?믣?穩▲겓?곭㎉?뺞셽??벴鵝볠뉵?뺡뇧??탪亮닷쨯?뽧굮?딀룪?쀣 ?987亮담걢??005亮담겓?뗣걨??큵2?꿩툤弱묆걮?╉걚?뗣걪?ⓦ굮?롢굢?뗣겓?쇻굥?ⓦ겏?귙겓?곲꺗躍귟쫸與▲굜?썲툊?뤷냵?㎯겗?썲툊??퐤營?겈?묆겏?꾠겂?잒┳?밤걢?됥 곮벴鵝볠뉵?뺡뇧??량?겹굮濾쒑㉫?쀣걼?귝?孃뚣겓?곲꺗躍귛뜕鵝띲겎??읃?х쉪?ょ돶?㎯겏?쀣겍?곩툊烏쀥뙑?뷴윜雅뷴룭野녶벧?ⓧ툟躍?걗?잆굤?ゅ땿邕듾퓷?됧룿?겹겓? ??걮?잋툓?㎯ 곥걪?뚣굢??꺗躍귞돶?㎯겏燁삣땿?귙겗翁ヤ퐪域삣땿?뤵겏??뼟?ｃ굮永뚦뭅?꾠겓?녷옄?쀣걼??
