近年來高齡化的趨勢席捲全球，而人口老化的趨勢則可能進一步衍伸到對於各項設施、休憩用地、公共建設等等的無障礙性需求增加，因此從總體物理環境檢視其對於高齡者的友善程度是值得深入探討的。基於此概念，本文依據高齡者的特性、行為模式和生活需求等文獻進行綜合性的回顧，針對公共開放空間之友善程度改善的可能性或可行性嘗試建立出對應在地高齡者身體機能之公共空間規劃設計原則。又因高齡者身體機能狀態與退化程度各地差異甚大，本文建議應結合各地高齡者失能程度狀態之評估為進行友善環境設計改善的參考，以失能狀態對應空間現況，進行可優先改善項目與內容排序，在資源有限的前提下，提供未來社區落實以高齡友善環境改善之參考。

The ageing trend could produce a need for designs for barrier-free purpose-built facilities, open spaces and public buildings. Hence, it is worth further investigating whether the present general environment is friendly to most elderly people. Accordingly, based on a review of the literature on the older population's characteristics, behavior patterns and living requirements, this research further explores the possibility of delivering age-friendly open spaces in Taiwan. The preliminary result of the work is expected to establish a design guidance system with indicators. The design guidance system could provide a tool to assess the level of age-friendliness of the physical environment of open spaces and identify the urgency of improvement, to further assist in providing age-friendly cities in Taiwan.
