Study on Evaluation of the Presence of Residents' Choice of Urban Parks Based on Accessibility to Urban Parks

In this study, residents' choice of park when more than one type of urban park is within service distance of urban parks was evaluated by using the accessibility to urban parks in Sakai City. Analysis was conducted with the geographic information systems (GIS) network analysis system. Results showed that, in the whole of Sakai City, about 40% of residents lived in neighborhood units with two different types of urban parks within their service distance. However, as regions with districts which underwent urban planning and development, those district residents were provided with a choice of parks. In the urban sprawl district, about 10% of residents lived in neighborhood units with two different types of urban parks within their service distance.本研究では、堺市を対象に、GISのネットワーク解析を用いて、都市公園へのアクセシビリティをある地域から異なる規模の都市公園に同時に到達できる選択性の評価を試みた。堺市全体では、2種類の規模の公園にアクセスできる人口割合は4割程度に留まっている。一方で、計画的市街地整備地区を含む地域では、都市公園の選択性が担保されているが、スプロール地域では、都市公園の選択性が約1割程度と低いことが明らかとなった。
