摘　　要：为降低道路改造过程中对现状交通的影响,研究了基于仿真模型的交通疏解方案。以滨海大道为例,通过现状调查,获取交通数据以及道路情况,在VISSIM软件中建立既有疏解方案仿真模型,输出包括节点的延误、拥堵段排队长度、路段的通行时间与平均速度等交通参数,识别既有交通疏解方案存在的问题,通过对比分析,结合工程实施条件,对交通疏解方案4个阶段进行仿真优化。结果表明,优化方案在各项参数上优于既有疏解方案,同时在疏解路段中,对关键拥堵节点优化效果更加明显。In order to reduce the impact on the current traffic in the process of road reconstruction,a traffic relief scheme based on simulation model is studied.Taking Binhai Avenue as an example,the traffic data and road conditions are obtained through the current situation investigation,and the simulation model of the existing traffic relief scheme is established in VISSIM.The traffic parameters including node delay,queue length of congestion section,travel time and average speed of the road section are output to identify the problems,and in the existing traffic relief scheme simulation optimization is carried out in four stages.The results show that the optimization scheme is better than the existing scheme in terms of parameters,and the optimization effect of key congestion nodes is more obvious in the relief section.
