摘 要：城市萎缩是全球一些正面临人口减少的大都市地区都需面对的一个问题。因此，即使人口正在下降，这些城市需要“智能收缩”，包括旨在满足居民生活需求的设计方法。本文的目的是开发一种可视化智能收缩的可行走性指示器。方法包括对大阪北部都市区进行统计分析、GIS分析和问卷调查。确定了以下四个结果。首先，蔓延地区的人口下降表明了每个城市的区域特征。其次，本文开发了一个由住户密度、设施便利性、道路连通性和交通安全性组成的步行性指标。第三，Wi（i），即每个居住区、扩展区和公共住房区的可步行性，对未来人口变化非常重要。最后，通过有关区域评价的问卷调查，阐明了该指标的有效性和有效性。综上所述，步行能力指标能够显示蔓延区域的智能收缩。
Abstract: Urban shrinkage is a problem that is faced by some metropolitan areas globally in urban cities faced with depopulation. Therefore, these cities require “smart shrinking”, which consists of design methods intended to satisfy residents’living needs, even though the population is declining. The purpose of this paper is to develop a walkability indicator for visualizing smart shrinking. The methods include statistical analysis by GIS analysis and questionnaire in the Northern Osaka Metropolitan Area where there are many small-sprawl areas. The following four results were identified. First, the population decline in sprawl areas indicates the regional characteristics of each city. Second, this paper develops a walkability indicator composed of household density, convenience of facilities, road connectivity, and traffic safety. Third, Wi(i), which is walkability in each residential area, in sprawl areas, and in public housing areas, is important for future population change. Finally, the validity and effectiveness of the indicator is clarified by questionnaires regarding regional evaluation. In conclusion, the walkability indicator is able to visualize smart shrinking in sprawl areas.
