摘要 本文主要目的是希望透過官方登記的自行車失竊案件之被害人、被害車輛、被害地點、報案特徵,系統性的檢驗自行車失竊之被害人、車、地及時等特徵,找到自行車失竊的情境因素。另一方面,本文也想透過分析結果,對照政府各單位目前的管理策略,找出現行符合情境預防特性,降低自行車失竊率的效果最好的策略。 本文運用臺北市政府警察局2007年至2009年的刑案紀錄表,針對自行車失竊官方的統計資料進行分析,總共分析案件數為718件。此外,也在自行車失竊熱點中選出2處臺北市最常發生竊案處所,親自觀察紀錄2處所之情境犯罪預防設計之特徵。本文主要研究發現有4點:(一)臺北市自行車竊盜發生以白天、捷運站、娛樂場所及學校附近居多;(二)自行車失竊被害報案人以男性、上班族或家庭主婦居多;(三)偷竊自行車者多數以徒手為之,並立即變賣圖利;(四)自行車失竊多屬機會犯罪,只要情境出現漏洞,即可能發生。針對自行車失竊的情境特性,本文最後也分別針對自行車車主、車商、警方與政府提出情境預防策略之建議。

The study analyzed the data of bike thefts based on the reports of the Taipei City Police Department Criminal records from 2007 to 2009, a total number of 718 cases. In addition, the author observed the features of the crime prevention programs at the two stolen bike hot spots in Taipei.
