| dc.description.abstract | 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.
