浅谈互通式立交变速车道在设计中应注意的问题

Talk about rhe Notes of Interchange Speed Change Lane in the Design Phase

互通式立交是高速公路车辆的集散口 ,而车辆在集散过程中的分流、合流与加减速又必须通过变速车道来完成。为使互通立交发挥其应有的作用 ,在设计中应对变速车道形式的选择、长度的确定。

Interchange is distributinb center of vehicles on Expressway,but diffluence,confluence and speedup of vehicles syould be completed on speed change lane.For making the interchange to play its tole,the type and length selection of speed change lane,and coordination between its profile design and main lane shluld be concerned in design. 〔
