① Life-oriented Approach and QOL

A new website about the life-oriented behavioral studies was just builthere.



Development of Cross-sectoral Urban Planning and Management Methods Based on Life-oriented Approach

The life-oriented approach argues that people’s decisions on various life domains are not independent of each other and that an understanding of life choices should not be constrained by the boundary of any single discipline. It should be developed as a common decision support method for various public policies. In the case of transport policy, it reasons that travel results from various life decisions and therefore any understanding of travel behavior is secondary to a fundamental understanding of life choice decisions. From the behavior viewpoint, the ignorance and inability of understanding travel behavior from the life choice perspective may lead to a biased estimation of travel demand and behavioral changes, and from the transport policy viewpoint, the ignorance and inability may lead to a failure of consensus building. In the case of urban policy, the relevance and importance of the life-oriented approach is more obvious because the urban policy needs to reflect people’s various life aspects into the policy decision-making process simultaneously.

1990年ごろから交通行動を、2000年ごろから交通を軸にしつつもより一般的な市民生活行動を対象に、市民生活を包括的で一体的に扱う学際的な学問体系「市民生活行動学」の構築に関する研究を行ってきている。そして、2010年度から2013年度にかけて研究代表者として基盤研究(A)(一般)科研費を獲得し、生活経営学、保健学、環境経済学、都市工学、交通計画学などの視点から低炭素型まちづくり、交通弱者モビリティ支援、都市観光促進、都心活性化などを対象に、今までの研究の集大成を図っている。今までTransportation Research Part B(交通分野の世界最高峰雑誌), Transportation, 土木学会論文集や都市計画学会学術研究論文集などにて108編査読付き論文、他126編論文を公表した。2001年にアジア交通学会優秀論文賞を、2007年に第3回米谷・佐佐木賞をそれぞれ受賞した。

I have studied travel behavior since 1990. Since 2000, I have extended the travel behavior studies to cover more general behavioral aspects in both urban and transportation contexts, by making full use of trans-disciplinary knowledge, including time use studies, health behavior theory, home economics, quality of life studies as well as travel behavior theory. As of April 2013, 108 refereed papers and 126 other papers were published in internationally recognized journals (e.g., Transportation Research Part B (SCI journal, the top transportation journal), Transportation (SCI), Transportation Research Record (SCI), Energy Policy (SCI), and Japanese well-known journals such as Journal of Infrastructure Planning and Management, Journal of the City Planning Institute of Japan). As a result of making various efforts, I successfully won one of the biggest scientific funds “Grants-in-Aid for Scientific Research (A), JSPS (Japan Society for the Promotion of Science)”. One of the papers were awarded as Outstanding Paper Awards by the EASTS (Eastern Asia Society for Transportation Studies) in 2001, and a series of papers were awarded as Best Research Award (KOMETANI-SASAKI Prize), Institute of Systems Science Research, Japan in 2007 (Prof. Kometani and Prof. Sasaki are two pioneers in Transportation Engineering in Japan).
