The concept of 15-min cities has recently received a lot of attention in recent research. However, the clear definition of a measurement for this concept has not yet been done at a neighborhood and city level across all continents and encompassing topological constraints. Yielding the question if 15 min is even the right indicator. In this study, we propose a method for determining how closely a city adheres to this concept using Open Data. We also propose an optimized method for generating communities that will assist us in discriminating walkability needs and validating generated communities. We discover that the number of communities meeting the 15-min target is inversely related to population growth and city area.

步行适宜性定义了可持续城市的社区

15分钟城市的概念最近在最近的研究中受到了广泛的关注。然而，尚未在各大洲的社区和城市层面上对这一概念的测量做出明确的定义，并包含拓扑限制。产生一个问题：15 分钟是否是正确的指标。在本研究中，我们提出了一种使用开放数据来确定城市对这一概念的遵守程度的方法。我们还提出了一种生成社区的优化方法，它将帮助我们区分步行需求并验证生成的社区。我们发现，达到 15 分钟目标的社区数量与人口增长和城市面积成反比。
