Abstract:	近年來政府大力推動公路路網建設以平衡城鄉間的發展，如已完工通車的國道5號(蔣渭水高速公路)與北二高均有不少的隧道工程，其中雪山隧道就屬國內最著名的長隧道工程。雪山隧道平常日皆能紓解現有車流，但每適逢春節連續假期、國定假日、例假日往往出現塞車情形。當交通需求持續增加至超過隧道容量時，隧道發生交通壅塞因半封閉特性易造成交通疏散與廢氣排除不易，而引發相當嚴重的交通惡化結果，甚至釀成嚴重事故。本研究對雪山隧道進行車流特性分析，並以旅行時間為控制依據，研擬不同路徑導引策略，透過策略中各個方案績效值之評定，以提供管理者作為決策參考。本研究以旅行時間最短為控制目標，研擬旅行時間、延遲導引與持續導引策略，並以導引時間、平均旅行時間、等候持續時間與平均延滯作為績效評估項目，評估其策略之效益。研究結果顯示，延遲導引時間越長，開始導引的時間越晚，總導引次數隨之減少，而平均旅行時間與平均延滯隨之增加。 In recent years the government vigorously impelled the road road network construction by to balance the development between the city and countryside. The tunnel projects can be found in National Expressway No.5, Jiang Weishui Highway and Northern National Highway No.2. In all of the tunnel projects, Hsuehshan Tunnel is the most famous long tunnel. The Hsuehshan Tunnel ordinary day all can relieve the existing traffic, but just happens to meet the Spring Festival, the nationally established holiday, the legal holiday date often has the traffic congestion. When the traffic demand increases continually to surpasses capacity of the tunnel, because the tunnel has the transportation clogged up half seal characteristic easy to create the transportation to disperse with the waste gas removes not easily, but initiates the quite serious transportation worsening result, even breeds the serious accident. This research mainly focuses on the traffic flow in Hsuehshan Tunnel and has an analysis on it. Travel time is controlling criteria, and to discuss different route guidance strategies. The thesis is expected to provide the managers suggestions through various performance evaluations. The shortest travel time is controlling target and to design the strategies including travel time, delayed guidance and continued guidance. The strategies are evaluated by duration of route-guidance, average travel time, time in queue and average delay. The research shows that time of delayed guidance increasing, beginning time of guidance is more later, times of total guidance decreasing, thus average travel time and average delay all increasing.
