| 摘要: | 捷運聯合開發大樓有別於一般社區大樓，其基地本身即位處於大眾捷運場站，縮短了家戶至運輸場站步行距離，大幅地提升公共運輸服務之可及性。然而受限於捷運站站體設施所需，導致捷運共構宅其地下空間時常與都市設計審議過程中所要求之小汽車停車位數有所出入，造成後續開發進度裹足不前。由此可得知，目前我國都市設計審議過程中，因對於捷運聯合開發共構宅小汽車之相關使用特性了解有所不足，當中損失之成本難以估算。為此本研究利用個體選擇模式構建個別家戶性質運具選擇行為模式，透過共構宅住戶進行問卷調查，據以得知影響家戶使用小汽車及大眾運具之影響因素，可就其入住前後之運具選擇差異得知捷運共構宅對於整體社會所產生之效益。並且針對歸納整理後之各重要變數進行彈性分析。
研究結果顯示：1. 根據羅吉特模式校估結果「坪數」、「大樓車位供給率」越大對於小汽車持有/使用上均有正向影響，反之越小則對於大眾運輸使用有顯著影響。2. 家戶旅運者經濟效益評估中可得知對於持有與使用小汽車之家戶而言，入住後無論係持有亦或使用小汽車之效用皆產生降低現象。而對於入住後使用大眾運輸之家戶，則其效用值呈現提升之情況。3. 環境效益評估結果，可得知對於碳排放部分，共構宅住戶於入住前後使用之通勤運具所產生之減碳效益為29.2%。並將入住前後所產生之總碳排放量相比，每年碳排放量減少約為26.9公噸。空氣汙染物部分，可發現減排效益皆約達50%以上，其中又以氮氧化物之減排效益最大，達62.01%。4. 由彈性分析可得知，捷運共構宅家戶隨著家戶坪數、大樓車位供給率越大，小汽車持有/使用之機率皆會增加；而車位供給限縮政策下，小汽車使用成本會有增加之情形，故經分析可進一步得知，小汽車使用之機率會有減少之趨勢，大眾運輸使用之機率會有增加之趨勢。透過本研究分析成果可作為後續捷運聯合開發共構宅相關規劃與政策推動之參考。
Transit joint development buildings’ are differing from community buildings’ since it locate on MRT station. Above all, it shortens walk distance of home among station; it also obviously increases public transportation accessibility. However, it limits in MRT station facility, to bring its underground space has a few different from be required quantity of the sedan cars parking; further, it causes development progress rate that was delayed. It can explain that in the process of city design deliberation, Transit joint development buildings’ sedan cars relevant usages and features are not enough comprehended, this is why the loss is hard to calculate the cost. Base on the study exploit individual choice model to build household transportation choice behavior model through resident survey, it can get actual effective factors between sedan cars and public transportations. It points out Transit joint development buildings’ for society as a whole benefits. On this point, it is able to compile vital data, and then analyze it.
The result shows as follows:
1.In term of the Logit model calibrated, floor plan and parking supply rate increased, it illustrate more positive utility for sedan possessions or using. On contrast, it will influence on public transportations obviously.
2.In household traveler economic assess, whether possess sedan cars or not, it utility both present decrease condition after live in; instead, using public transportation present increase condition.
3.In environment assess, carbon emission decrease 29.2%. Compare with before, the carbon decreases 26.9 ton/year. About air pollution, it can found decrease emission approximately 50% up; especially Nitrogen oxides decrease the highest, almost 62.01%.
4.According to flexible analysis, MRT co-house depends upon floor plan and parking supply rate to change. The floor plan and rate increase, the sedan cars possession chance would be raise. Also, the parking supply limit policy was conducted, sedan cars cost will increase. As a result, through analysis data that know sedan cars use rate will decrease. Otherwise, the public transportation will increase. By way of this study analysis result, it can be a plan and promote policy’s reference of Transit joint development buildings. |
