摘要

公共自行車為一種無汙染且不耗能的交通運具，不但可節省使用者購買自行車的成本，民眾亦可透過公共自行車轉乘大眾運具或完成短程旅次需求，因此不論在國外或是國內，公共自行車逐漸成為一種熱門的綠色運具。臺北市政府自2011年推出臺北市公共自行車(微笑單車)以來，使用人數逐年上升，惟吸引民眾使用臺北市公共自行車的因素尚未有相關研究探討，故本研究想了解影響民眾使用臺北市公共自行車的因素，以作為未來政府擴大規劃建設公共自行車服務之建議。
本研究以計畫行為理論為基礎，並參考過去自行車使用意向之研究，加入其他擴充變數，期能以多元面向探討影響民眾使用公共自行車之因素。本研究透過問卷調查方式，以網路與紙本同步發放方式蒐集樣本，並將回收之有效樣本以結構方程模式方法，建構出臺北市公共自行車使用者意向之結構方程模型。研究結果顯示民眾使用臺北市公共自行車受到習慣、公共自行車環境滿意度、態度、知覺行為控制、天候承受度、環保意識與感知機動需求之正面影響，主觀規範則對意向具有負面影響。未來若欲提倡臺北市公共自行車之使用率，改善自行車道路交通工程設施的完整度、規畫擋風遮雨的自行車道、並加強民眾的環境保護觀念等，將對提升臺北市公共自行車之使用率有相當大的助益。

The public bicycle system is an environment-friendly transportation tool which could decrease air pollution and fuel consumption. By using the public bicycle system, users could not only save the cost of bikes purchasing but also complete their short trips; moreover, as a feedering mode, the public bicycle system could provide citizens a convenient way to approach another kinds of public transportation systems. Therefore, the public bicycle system has become a popular green transportation all around the world. The Taipei City Government launched the Taipei Public Bicycle System (YouBike) in 2011, and the number of users is increasing year by year. However, so far the underlying motivation which drives people to use YouBike is still unclear. Therefore, the aim of this study is to understand the real factors attracting people to use YouBike; furthermore, for the expanding of the public bicycle system in the future, the results of this study could also offer the city government some useful information.
In order to completely understand and predict the motivation force of using the public bicycle system, the study, based on the Theory of Planned Behavior (TPB) and several previous studies about the users’ intentions, used additional associated variables. Moreover, we used dual ways to collect the data: surveys either gathered from the Internet users or collected from the pedestrian. By analyzing the samples, we built up the structural equation model of individual’s intention according to the related method. The results show that habits, the environment satisfaction of public bicycle system, attitudes, perceived behavioral control, weather and terrain resistance, green identity, and perceived mobility necessities could have positive impact on using the public bicycles; on the other hand, subjective norm could have negative effects on individual’s intention. Taken together, based on the results of this study, for the sake of promoting user intention of YouBike in the future, improving the integrity of the traffic facilities, constructing the shelters against wind and rain along the bike paths, and enhancing people's eco-friendly concepts could be considered to enhance the individual intention toward using YouBike.
