15分都市
歩くかあるいは自転車に乗るかして15分以内のところに、生活に必要なものがすべてそろっていること。
どうやら、「スマート・シティ」や「スーパー・シティ」は、こういう発想とはあまり関係のないもののようだ。
自動運転バス、空飛ぶクルマ、物を運ぶドローンなどのことばかりで。
住民の「生活構造」とか「民主主義」とかの理念とは関係のないところで、地域社会におけるデジタル・トランスフォーメーションが構想されているように思う。
The idea is relatively simple. Residents should have everything they need within a 15-minute walk or bike ride from home.
Forget megaprojects. The new priority was keeping it local.
While the idea of a small town existing within a city is not new – US urbanist Clarence Perry advanced the concept of the “neighborhood unit” in the 1920s; Jane Jacobs penned an ode to the little society of her Manhattan block – for most of the 20th century, US development patterns moved sharply away from idealizing the local. Politicians forbade the density necessary to support local amenities on the grounds that it was a driver of squalor and crime. Residential neighborhoods were plotted far from commercial centers, and many banned even small merchants like coffee shops or convenience stores. In 2017, the average shopping trip in the US was more than 7 miles.
