摘　　要：水果湖隧道是城市二环线的重要组成部分,是衔接城市南北向交通出行的重要快速通道,自2014年开始长期处于严重拥堵状态,直接影响二环线整体通行效率的发挥。为缓解水果湖隧道拥堵状况,采取现状航拍调查的方式,运用VISSIM仿真软件,分析挖掘隧道的车流来源和时空分布特征,从初始拥堵的内在机理分析隧道拥堵的真正原因,提出改善水果湖隧道拥堵的建议,并对隧道实际运行状况和改善方案进行仿真模拟和对比分析。结果表明,改善措施对缓解水果湖拥堵有较好的作用。The Shuiguohu Tunnel is an important part of the city's second ring road and an important fast track connecting the city's north-south traffic.It has been in a state of serious congestion for a long time since 2014,which directly affects the overall efficiency of the second ring road.In order to relieve the congestion of the Shuiguohu tunnele,the present situation of aerial survey is adopted and the VISSIM simulation software is used to analyze the real cause of the tunnel congestion from the internal mechanism of the initial congestion,and suggestions to solve the congestion of the Shuiguohu tunnel are put forward the actual running condition and improvement scheme of the tunnel are simulated and compared.The results show that it has a better effect on alleviating congestion.
