摘要

隨著運輸科技之迅速發展與民眾運輸需求之日益擴張，運輸系統無論在系統設備、操作環境及組織架構上均較以往複雜許多。如何維持此一龐大系統正常運作並保有一定之安全水準，確實需要一套有效率之系統安全檢核制度，隨時掌握系統之潛在安全問題，並作好事前之防範措施。本研究透過系統安全管理相關文獻之回顧與整理，嘗試為運作中之運輸系統建立一套如何檢核系統安全問題之作業流程，以引導運輸專業人員如何在錯綜複雜之運輸系統中蒐尋潛在之安全問題、評估其風險、分析其發生原因與時機、並研提改善之措施與建議。本研究並且以台北捷運公司為例進行實證之研究，研究結果顯示該公司所面臨之「高風險」系統安全問題計有「民眾臥軌自殺事件被媒體報導出來後，造成其他民眾仿效臥軌自殺」、「月台上乘客過多，發生人潮推擠情形」、「設備採購時間過長，導致短時間內無法維修」、及「國內外材料短缺，導致無法進行維修」，值得台北捷運公司重視並加以注意改善。

With the rapid advances of transportation technology and rapid growth of demand in transportations, our transportation system has grown into a huge and complicated system. An efficient safety monitoring approach is then necessary to keep the transportation system operating with a high level of safety performance. This study aims to develop a systematic approach to explore the safety issues of transportation system and evaluate their corresponding risks individually. The focus group method was first used to collect the preliminary ideas about the safety issues of transportation system, and a questionnaire was then established based on those preliminary ideas to gather the opinions about the occurrence frequency and severity for each safety issue. The risk assessment was finally applied to determine the degree of danger for each safety issue. An empirical study of the Taipei Rapid Transit Corporation (TRTC) was conducted in this research. Some serious safety issues for TRTC are explored and several improvement suggestions are also raised in this study.
