大眾捷運共構住宅運具選擇行為暨停車供給政策之探討－以台北地區為例

大眾運輸導向發展（Transit Oriented Development, TOD）已為各國都市發展的重要政策，國內對捷運系統聯合開發住宅亦積極採取TOD的發展策略。然而，國內都市設計審議過程卻對捷運共構宅小汽車停車位設置數常有爭議。首先，本研究蒐集並調查台北地區捷運聯合開發住宅之家戶運具選擇行為資料，分別建立家戶小汽車持有及運具選擇模式，探討家戶運具使用特性及影響因素。其次，透過捷運共構宅家戶入住前後運具選擇行為分析，以比較入住前後小汽車持有及運具使用之變動差異。最後，分析捷運共構宅相關供給特性對家戶小汽車持有及運具使用之影響，進而建議捷運共構宅採取「住宅坪數較小與停車位供給限縮」之開發策略，降低共構宅停車需求之外溢性，以達提升大眾運輸使用之政策目標。

Transit Oriented Development (TOD) policy has been highlighted in the urban development of most countries. TOD strategy in the MRT joint development of residential cluster is also actively adopted in Taiwan. However, some of controversies always happened to decide the appropriate quantity of car-parking space in the urban design review process. Firstly, in the study we investigated and collected the associated data of the household mode-choice behavior characteristics of MRT joint-development residence in Taipei area, and then explored the causal relationship between the characteristics and the influencing factors of household's mode usage. Secondly, the mode choice model was adopted to analyze the household's mode-choice behavior, to compare the change differences between the before-and-after mode choice behaviors in the MRT joint-development residence. Finally, we analyzed the influence on the car-ownership and the mode-choice behavior characteristics, and consequently suggested that the development strategy of ＂deducting the square-feet of house and supply of car-parking space＂ should be adopted by the MRT joint-development residence, and then the externality of overflow of car-parking demand can be diminished, and the synergy of TOD can be achieved in promoting the mass-transit usage.
