摘　　要：在高速公路的大交通量、小间距超多车道复合式互通立交中,当最小辅助车道长度不满足的情况下需设置保障行车安全的集散道。综合考虑集散道交织区的几何构型、车道数、通行能力需求与车辆换道驾驶行为,构建集散道交织区的最小长度理论计算模型,提出最小长度推荐值;利用SUMO微观交通仿真软件,验证集散道交织区最小长度推荐值的合理性。研究表明:模型计算结果具有较好的合理性和工程适用性,能满足集散道交通安全和通行效率的需求,可为高速公路超多车道复合式互通立交集散道交织区设计以及完善相关规范与设计准则提供理论依据。In the super multi lane expressway composite interchange with large traffic volume and small spacing,the collector distributor lane is set up when the minimum auxiliary lane length is not met.Considering the geometric configuration,number of lanes,traffic capacity requirements and vehicle lane changing behavior of the weaving area of the collector distributor,the theoretical calculation model of the minimum length of the weaving area of the collector distributor is constructed,and the recommended minimum length is proposed;Using sumo microscopic traffic simulation software,the rationality of the recommended minimum length of the weaving area of the collector distributor lane is verified.The research shows that the calculation results of the model have certain rationality and engineering applicability,and can meet the requirements of the traffic safety and traffic efficiency of the collector distributor,which can provide a theoretical basis for the design of the weaving area of the collector distributor of the super multi lane expressway composite interchange and improve the relevant specifications and design rules.
