摘要

臺北市的第一項公共自行車服務－YouBike營運至今，已超過106,895,634租借次數。臺北市的公共自行車設置在全臺已較為完整，但以使用者經驗觀察，現有政策的新設站三項標準仍不足以符合公共自行車使用者租借需求，因此以微笑單車（YouBike）租借使用者端的需求為來源，利用開放街圖（OpenStreetMap, OSM）中自發性地理資訊（Volunteered Geographic Information, VGI）找出站點周遭對公共自行車站使用率影響較大的因素，推估在何種特性地點下的YouBike租借站使用率較高，針對不同道路品質：自行車道與人行道的有無；與不同租借地：捷運站、學校、河濱自行車道入口，評估公共自行車租借站營運的效率與使用者便利性。

The first public bicycle system of Taipei City, YouBike, has the total rented over 106,895,634 times. Taipei is the city providing most well-developed public transportation systems and public bicycle systems in Taiwan. Currently, Taipei government builds new YouBike systems with 3 standards, but it still not enough to fit the need of YouBike riders. This study is based on the need of YouBike user, we extracted geographic data from OpenStreetMap(OSM) and the volunteered geographic information (VGI) such as roads, sidewalks, bicycle lanes, and popular destinations in Taipei city. These data were treated as the influence factors for location analysis of stations. The statistics is used to evaluate the efficiency of the circulation of bicycles, in order to find out the suggested location of the docking stations and improve the efficiency and stimulate more usage.
