都市家戶機動車輛持有類型與使用行為之研究

Abstract

本研究之主要內容在了解都市家戶機動車輛持有過程與影響因素，以及現 有機動車輛的使用行為，分析機車與小客車的替代性，並比較大眾運輸頗 為發達的台北市，與較仰賴私有運具的新竹市之家戶機動車輛擁有行為差 異。據此擬定四大研究主題，分別為都市家戶機動車輛擁有類型分析、機 動車輛擁有類型與使用行為關係分析、家戶機動車輛持有狀態改變的時間 間距分析、及家戶增購第二部機動車輛的車種選擇分析。藉由問卷設計調 查並利用次數統計分析、指數迴歸模式、二元羅吉特模式分別檢驗各研究 主題相關影響因素之顯著性。研究結果顯示運輸環境不同的都市會衍生相 異的機動車輛持有與使用行為。 This research is undertaken to explore the patterns of motor vehicle ownership for the households in urban area, and compare the difference of household charact- eristics as well as behavior of vehicle usage among different patterns. Based on the developed conceptual framework about the patterns of motor vehicle ownersh- ip defined by the combination of motorcycle and auto- mobile ownership, a survey was conducted to collect required data. We first analyzed the patterns of motor vehicle purchasing sequence for the motorized households in Taipei and Hsinchucities, and found the households in Hsinchu City tend to own more motor vehicles than those in Taipei City. We might draw theconclusion that convenient public transportation servive and severe parking space deficiency will reduce the willness to own motor vehicle for the households in Taipei City. We also found motorcycles are getting attractive as the parking and congestion problems are getting worse. An Exponential Regression model is established to formulate the elapsed-time for purchasing another new motor vehicle, and try to explore the related factors affecting the decisions ofmotorized households. Fur- thermore, a binary logit model is used to realize the important factors affecting the vehicle type choice of motorized households when they decide to buy one additional motor.
