Outline of Final Research Achievements

Children’s Independent Mobility (CIM) can be defined as children’s freedom to travel around their own neighborhood or city without adult supervision, which is an important factor in children’s health and physical, social, and mental development. CIM has been discussed since the 1970s and, in many studies, was evaluated by six license which is one of the indicators of CIM. However, the factors affecting CIM in Japan are not clear.
The purpose of this study was to clarify these factors by using ordered logistic regression modeling. In the findings, three points were revealed. First, it was shown that CIM was affected by guardians' concerns about traffic, which was consistent with findings in previous studies. Second, it was confirmed that the factors affecting each license are different. Finally, CIM was proved to be consistently affected by the freedoms or limitations assigned to guardians when they were children.

Academic Significance and Societal Importance of the Research Achievements

本研究は「子供の移動自由性」に着目した研究である．最近，欧米で研究成果が多く見られる研究分野であるが，日本においてはほとんど研究成果が見られない．
一般的に，子供の頃の経験が，大人の意思決定に大きく影響するといわれており，本研究の成果においてもこの点が明らかとなった．一方で，子供の移動自由性と安全性はトレードオフの関係にあることが指摘されており，単に子供の移動自由性を高めればよいというわけではない．そのため，子供の移動自由性を高めつつ，安全性を確保したまちづくりを実践することが重要である．以上より，子供の移動自由性に着目した本研究の成果は，学術的にも社会的にも意義があるといえる．
