台北捷運通車至今已達十年，雖然隨著路網擴展乘客漸增，但根據統計資料顯示汽機車的持有不減反增，且目前搭乘情況距離政府設定搭乘大眾運輸運具比例達60%之目標仍有相當的成長空間，顯示仍有相當比例的民眾不使用或不願意搭乘捷運。另外，全球觀光客已將台灣視為消費平價的觀光地點，又根據文獻發現60％的遊客於旅遊時會將交通列為首位，而台北市是一個相對發展良好且充滿國際化的都市，並有較完整的大眾運輸系統，為了提升大眾運輸使用率，因此，影響使用者搭乘捷運的因素為何，又國人與國際觀光客的看法有何差異便值得探討。 從相關文獻探討中可知影響消費者搭乘捷運的因素，包括：搭乘捷運能快速到達目的地、等車時間短、捷運準點性高、搭乘環境是安全的、搭乘環境是舒適的、捷運票價合理、捷運車站內設施乾淨、提供外語的資訊導覽、有充足的無障礙設施、捷運車站周邊人行步道設計舒適、捷運車站周邊的業種多元、捷運車站附近逛街方便、捷運車站服務人員態度友善專業、容易了解如何搭乘捷運、捷運轉乘系統方便、捷運資訊充足、捷運系統資訊標示清楚、捷運車站設計具有地方特色、捷運車站設計具有景觀意象、捷運車站為顯著的地標、住宿地點緊鄰捷運站、捷運至觀光遊憩地點具方便性、捷運系統能串連許多景點等。 本研究之目的在於調查國人與國際觀光客搭乘捷運之體驗與評價，透過因素分析所粹取出的構面來瞭解搭乘捷運所重視的因素，本研究分別調查304位國人與312位國際觀光客，研究結果顯示，國人與國際觀光客分別在社經特性、旅遊行為及搭乘捷運經驗上，對於搭乘捷運重視因素有顯著性之差異，最後針對分析結果提出三大努力目標與策略：（1）高可及性的運輸系統：提高可及性、完善轉乘系統、串連捷運周邊景點；（2）豐富的資訊系統：提供完善資訊、提升服務人員專業性；（3）友善鮮明的空間與多元的使用：注入設計感、增添形象性、多元化土地使用、人性化步道設施等，以供提升大眾捷運系統使用率的參考。 / Taipei MRT has already operated more than ten years.
