公路隧道屬一大型密閉空間，發生火災時會造成隧道內高溫及熱氣濃煙，逃生及減火行動均會受到阻隔。火災搶救首重於初期應變，因此高速公路管理單位(高公局行控中心、公警單位及工務段)是否能夠及早偵知火警、確認皮通報，並通報消防救援單位儘速抵達擔負初期滅火的工作等，都是災情是否擴大的重大影響因素。本文針對臺灣北宜高速公路雪山隧道，藉由訪談管理單位、所轄地方消防單位及實地調查等方式，對初期應變及支援單位之地理位置、救援能力（人力、機具設備）等進行調查分析，並根據救災單立與交流道之相關位置、距離等資料，做為後續估算救援反應所需時間，以提供國內其他隧道管理及救災單位參考，亦可提供建置救援標準作業程序之基礎資訊。

Road tunnel is a kind of large enclosed spaces. Evacuation and fire suppression will be obstructed if fire occurs inside a tunnel with high temperature, heat and intensive smoke. It is very important to make initial emergent response during fire incidents. As a result, whether the highway management units (traffic control center of Taiwan Area National Freeway Bureau (TANFB), traffic police unit and public work section) can detect the fire alarm, confirm and transfer earlier, and fire station as well as rescue units can arrive speedily are all the critical factors to cause the disaster getting worse or under control. This research examines the geographic location and rescue capacity (human resources, mechanical equipments, etc.) of the units which are responsible for initial emergency response in Taipei_Ilan highway Shiue Shan Tunnel by interviewing the highway management units and local fire stations and investigating the post. This research also estimates the distance and the reaction time require according to the characteristics of related road management nits, fire stations and intersections. These required data could be provided to develop standard operation procedure.
