常州市“日”字形快速路网中长虹路立交方案设计

On Changhong Rd.Interchange Plan Design of 日-type Expressway Network in Changzhou

常州市长虹路立交位于"日"字形快速路系统的西南角点。环线快速路系统中转角处立交形态主要由立交节点的射线方向与环线方向的交通地位来确定。通过对长虹路立交交通定位的分析,初步确定了环线方向采用主线标准、射线方向交通采用匝道标准的立交形态。最后,介绍了长虹路立交的完善方案。

Changhong interchange is located on the southwest corner of 日-type expressway system in Changzhou.And the shape of interchange on the corner of a loop line expressway system is determined by the node's ray line direction and the traffic position of the loop line direction.Through an analysis of Changhong Rd.interchange traffic position,the loop line traffic will adopt the main line standard initially and the ray line traffic will adopt ramp standard interchange shape.Finally,relevant improvement plan of Changhong Rd.interchange is introduced in this paper.
