摘　　要：为进一步优化城市快速路的出入口匝道设计,分析了布置在高架快速路出入口匝道的交叉口交通特性,研究了合理化交织区设计、立体分离横向道路直行交通、均衡路网流量和分担疏解功能等空间布置策略,并提出了各种优化方案的适用条件。In order to optimize the design of on-ramp and off-ramp of urban expressways,the traffic characteristics of intersection at the on-ramp and off-ramp of elevated expressway are analyzed.The spatial layout strategies of rationalizing the design of interleaving area,three-dimensionally separating the direct traffic of the transverse road,balancing the road network traffic flow and sharing the dispersal function are studied.The applicable conditions of various optimizing schemes are put forward.
