聯絡通道減作會使隧道內管線佈設及旅客逃生狀況改變，本文以蒙地卡羅法進行 數值模擬，藉由評估台北捷運系統聯絡通道減作前後風險機率之變化，瞭解減作案對旅客逃 生之影響程度，其分析程序並可於相關工程規劃時應用參考。

　　　　　The layout of service utilities and passenger evacuation will be affected by the criteria of crosspassage set up. Based on the Taipei MRT original planning, this paper utilizes the Monte Carlo simulation to assess the risk of the passenger evacuation with the number of crosspassages reduction in tunnels. The procedure of the analysis for the number of crosspassages reduction can also be used for the planing of related engineering fields.
