大眾運輸系統無法提供點對點(door to door)的交通,使用步行轉乘大眾運輸工具限制了民眾的搭乘意願。降低大眾運輸系統使用者的旅行時間並達到轉乘之順暢性成為都會交通改善的重點。本研究首先蒐集國內外大眾運輸延伸旅程及個人電動載具相關文獻,同時實施田野調查,探討臺北市交通特性與其他國家綠色運輸執行成效。其次,以人機環架構理論分析個人載具使用狀況及其適用性。隨後,以使用者需求為基礎,針對現有個人電動載具,分析其功能特性與人機介面,包括騎乘距離、時間、姿態、載具速度與重量。最後提出延伸臺北捷運系統之可攜式個人電動載具規劃。 研究結論:(一)捷運延伸旅程屬於短程移動:約0.4~3km,宜以低速模式提高安全性。個人電動載具最適合之速度為5~15km/hr,大約花費 4.8~12分鐘完成延伸旅程。(二)電動載具理想重量為10~40kg,輕量且可摺疊設計會增加使用者便攜性。(三)低速騎乘狀態下,適合之騎乘姿態為站姿或高坐姿。騎乘姿態影響車體設計,站姿或高坐姿有利於載具車身小型化與輕量化,並且方便上下載具。其中,高坐姿具短暫歇息特性,可快速起身坐下,較站姿適用於更廣泛之族群。 以捷運系統延伸旅程為目標,理想之個人電動載具應定位為短程移動(低續航力10-20km)、低速(5~15km/h)及自由度高之騎乘姿態。個人電動載具輕量化,可降低成本,尚可提昇載具的易攜性,有效改善民眾使用大眾運輸系統的意願。
Walking access to transit drops dramatically with distance from transit stations, In order to increase access to locations that are not accessible by mass transportation, this study attempts to enhance the future role of personal electric vehicle (PEV). Firstly, literature research was undertaken on daily journey patterns of Taipei metropolitan population and study of existing personal electric vehicles was carried out, in which existing PEVs were categorized. Secondly, analysis to PEVs cruising speed, riding posture, and vehicle weight was undertaken, according to the investigating scenarios and usability requirement. The results:Distance to get to MRT stations is between 0.4-3km for Taipei commuters. Thus, the advised speed of PEVs is 5-15km/hr, with an average riding time of 4.8-12 minutes. Proper vehicle weight is suggested between 10-40kg. A light-weighted and easy-carry PEVs is proposed to fulfill residents’ needs of short-distance transport for access to public transport. As for riding postures, for faster rides, it is suggested to apply standing or semi-seated riding postures. Users of semi-seated PEVs can change their riding postures at will. An ideal PEV for accessing to transit is characterized by less cruising range, low speed and flexible riding posture. A light-weighted PEV provides commuters with lower cost and, most importantly, portability in the MRT environment.
