地域公共交通の確保に資する交通手段としてオンデマンド交通が挙げられるが、利用者数の増加とともに希望の乗車時間に予約ができない面も指摘される。そこで、本研究では、オンデマンド交通の予約不成立の発生状況に着目し、どういった利用者に予約不成立が生じているのか、そして、それがどのタイミングで何故生じているのかを明らかにすることを目的とする。データの集計結果から、利用登録者や乗車回数に関わらず予約不成立となる可能性があること、予約不成立の 5～6 割は乗車希望の 2 時間以内に予約申込を行っていること、予約不成立の 3～5 割は 2 時間以上先しか空きが無いためであることが明らかとなった。そして、これらの事項が予約不成立を解消するための施策の根拠となる点で、意義があるものと考えられる。

 The purpose of this study is to show how retired workers are supported in Toyota city, Aichi prefecture to engage in agriculture, and the significance of that support. Toyota city is renowned for its automobile industry. During the period of rapid economic growth, the automobile industry attracted many workers from inside and outside Toyota city. However, since around 2000, when many workers started to reach retirement age, the issue of how to help them find a place in the community outside their companies has been a challenge. Toyota city also faces the challenge of how to respond to a declining number of people engaged in agriculture. To address both of these problems, in collaboration with the Japan Agricultural Cooperative (JA), Toyota city established the Agricultural Lifestyle Support Center, where retired workers can learn agricultural skills. The Center helps retired workers transition smoothly from corporate life to agricultural life by providing guidance and information on available farmland, as well as leasing agricultural equipment. Toyota city and JA also help develop sales channels for produce grown by retired workers.In Toyota city, retired workers from other areas who have no farmland to cultivate are also regarded as prospective farmers in the same way as retired workers who were originally from the local area and who own farmland. Support is provided equally to both categories of retiree. It is reasonable to say, therefore, that these support measures are significant in that they help prevent farmland from being abandoned with the help of retired workers, who are also supported as prospective farmers. Consequently, creating a place where farming skills can be taught and support can be provided for marketing the resulting produce is important for both retired workers and the local community.
