摘　　要：服务型互通立交作为高速公路的重要节点,若既有收费设施不匹配,会严重影响路段的通行效率,而收费站的改扩建设计对提升既有高速公路整体服务水平而言至关重要。文章以济南东互通立交改扩建工程为研究案例,针对常规收费站改扩建设计中存在的车道过多、交通流交织降低通行能力问题,提出采用同向分离式收费站和设置无岛式收费车道的设计方案,解决出口收费站前交通流交织问题。研究可为高速公路改扩建项目设计提供借鉴参考。As the important node of expressway,the service-oriented interchange will seriously affect the traffic efficiency of the section if the existing toll facility is not matched.The reconstruction and expansion design of the toll station is crucial to improve the overall service level of the existing expressway.Taking the reconstruction and expansion project of Jinan east interchange as the research case,aiming at the problems of excessive lanes and reduced traffic capacity caused by traffic flow interweaving in the reconstruction and expansion design of conventional toll stations,the design schemes that adopt the syntropic separated toll station and set up the island free toll lane are put forward to solve the problem of traffic flow interweaving in front of the exit toll station.The research can provide reference for the design of expressway reconstruction and expansion project.
