摘　　要：为保证渝长扩能项目实施后龙盛主线收费站的服务水平与运行安全性,对互通式立交与主线收费站的净距进行研究,通过建立数学预测模型,模拟车辆进入收费站前后的行驶轨迹,对标志反应、寻找间隙、变换车道、确认出口这4个驾驶阶段进行距离分析,计算最小净距值,并提出相应的交通优化措施,使改建后的互通式立交与主线收费站的最小距离满足车辆运行安全的要求。该研究对类似工程设计中互通式立交与收费站的最小间距的设计提供一定的指导。In order to ensure the service level and operation safety of Longsheng main line toll station after the implementation of Yuchang capacity expansion project,the net distance between the interchange and the main line toll station is studied by establishing a mathematical prediction model and simulating vehicles before and after entering the toll trajectory to analyze the distance of the four driving stages of sign reaction,search for gaps,change lanes and confirm exits,calculate the minimum clearance value,and propose corresponding traffic optimization measures to enable intercommunication after reconstruction.The minimum distance between the type interchange and the main line toll station meets the requirements of vehicle operation safety.The research results are of great significance to the interchange in similar engineering design.
