臺北市長期以來欲推廣大眾運輸使用率，且不斷建設捷運系統之路網，希冀降低民眾使用私人運具之頻率，然而擴大捷運服務範圍之作法對於大眾運輸市占率的提升成效有限。造成使用率無法提升的原因眾多，從大眾運輸導向發展模式可知步行環境亦為其中一項因素，惟過去研究中多僅針對單一項目進行探討，諸如步行距離、可及性等，而未整體性就步行環境，以及從民眾需求與感知予以探討。因此，本文以捷運周邊整體步行環境營造之角度切入，利用結構方程模式驗證整體步行環境五面向（安全性、舒適性、便利性、可及性、通用性）對於民眾搭乘捷運意願之影響，藉以提出符合民眾實際需求的步行環境改善策略，以期提升民眾搭乘捷運之意願，進而提升大眾運輸使用率。

Taipei City Government has been expanding the City’s Mass Rapid Transit network to increase public transportation utilization and reduce the frequency of people using private vehicles. However, public transportation utilization has not increased significantly. Utilization is affected by many factors, such as the walking environment from the transit-oriented development (TOD). However, most studies only focus on a single item, such as walking distance and accessibility of MRT, rather than discussing the whole walking environment based on user needs and feelings. Therefore, this study employs structural equation model to analyze the impact of the five aspects of the whole walking environment around the MRT on people's willingness to take the MRT, namely safety, comfort, convenience, accessibility and universality. Finally, we propose a walking environment improvement strategy that meets the actual needs of the people based on the results, and thus help increase public transportation utilization.
