常州至溧阳高速公路前马枢纽复合式立交通行能力研究

Research on Capacity of Qianma Junction of Changzhou to Liyang Expressway

以前马枢纽的设计方案为研究对象,分析了前马枢纽周边交通状况,受前后建设条件限制,枢纽采用复合式单喇叭形方案,校验了复合式枢纽前后的基本道路通行能力、互通匝道与高速公路连接处的服务水平和交织区服务水平。研究表明:2033年前马枢纽的主流向为常州往广德方向,前马枢纽的设计方案,能满足道路需求,枢纽匝道与高速公路分合流点的服务水平为三级以上,基本道路的通行能力为二级。

This paper takes the design of the Qianma hub as the research object,analyses the traffic condition around the Qianma hub,restricted by the construction conditions before and after,the hub adopts the compound single trumpet type scheme,calibrates the basic road capacity before and after the compound hub,the service level of the interchange ramp and the highway connection and the service level of the interweaving area.The study shows that the mainstream direction of the Qianma hub in Changzhou to Guangde in 2033,and the design scheme of the Qianma hub can meet the road demand,the service level of the hub ramp and highway merging point is above level 3,and the capacity of the basic road is level 2.
