機車失竊影響因素與因應對策之研究-以新竹市為例

Abstract

由於機車的許多特性適合於台灣地區使用，使得機車在台灣成為受歡迎的交通工具，且數量與日遽增。而機車引伸出的問題不僅是停車問題、交通安全問題及環保問題，機車的失竊問題在台灣也是相當嚴重。以往許多研究皆針對機車的停車問題與交通安全問題予以探討，然而卻甚少對於機車失竊問題予以研究。故本研究針對機車失竊的問題，探討其影響因素及研擬因應對策，以求能改善機車失竊問題。 本研究透過問卷調查方式收集機車失竊之相關資料，並對其以交叉分析及存活分析之方式予以探討。以交叉分析方式探討各假設之機車失竊影響因素與機車失竊間之關係，並將與機車失竊有顯著影響之影響因素再以存活分析方式探討，進而對機車之新舊以分層分析之方式分析，以探討機車新舊間之差異。瞭解影響因素之後並計算機車失竊之風險，以及對機車失竊問題研擬因應對策。 研究結果顯示，顯著影響因素為機車的新舊、機車的廠牌、使用者上鎖習慣及停車時之考量，而在停車環境方面則為尖峰時間、下班時間與假日時機車較容易失竊，而地點則為學校或住宅區較容易失竊。另外廠牌以光陽機車與三陽機車較容易失竊，而新的機車與舊的機車則以新的機車較容易失竊，且新的機車與舊的機車差異很大，新機車的生存率在存活時間為20個月之前都呈現快速下降，而舊機車的生存率則一直呈現平緩下降的趨勢。 另外在計算機車失竊風險方面，光陽機車平均每使用3.54年便可能發生一次機車失竊事件，而三陽機車則平均使用8.49年可能發生一次機車失竊事件。在瞭解機車失竊影響因素後，本研究更針對影響因素研擬解決機車失竊之因應對策，以提供機車使用者與相關單位參考。

More than ten million motorcycles run on the streets every day in Taiwan. Motorcycles have been the most important vehicles and significantly contributed to Taiwan's economic development for more than three decades. However, the rapid increase of motorcycles has also brought a lot of problems to the society, which include parking problem, traffic safety problem as well as environmental pollution problem. But a problem hardly ever to study is motorcycle-theft. There are average 518 motorcycles being stolen every day. A significant proportion of the motorcycle users have experienced losing their motorcycles. This study is undertaken to explore the factors affecting motorcycle-theft. Face-to-face interviews with motorcycle users were conducted to collect motorcyclists' parking behavior and experience of losing their motorcycles. Survival analysis method is then used to formulate the lifetime (the time to keep the motorcycle) as a function of motorcycles' characteristics and motorcyclists' behavior. The study results show that age of motorcycles, location and time of parking, motorcyclists' attitude and behavior are the significant factors to determine the risks of their motorcycles to be stolen. The results of this study not only explore the factors affecting the risk of losing motorcycles, but also provide a set of valuable information to draw the strategies to fight with motorcycle-theft.
