摘　　要：交通诱导是交通需求调控的重要手段,对于缓解道路交通拥堵、提高交通系统运行效率具有重要意义。本研究针对区域路网的交通诱导屏的诱导问题,给出诱导启动判断、动态交通分配、诱导信息发布等诱导全套方法,在动态交通分配过程中,采用相继平均法作为统一迭代框架,兼顾系统最优和用户均衡两类目标,且迭代过程考虑诱导屏的实际可显示信息约束,确保诱导方案能够通过诱导屏有效传达。最后,以福州市的区域路网作为案例对方法进行说明,行程时间可节省12.7%。Traffic guidance is an important means of traffic demand management,which is of great significance for alleviating road traffic congestion and improving the operational efficiency of the traffic system.In this study,aiming at the guidance problem of traffic guidance screens in regional road networks,a complete set of guidance methods such as guidance start judgment,dynamic traffic assignment,and guidance information release are given.There are two types of objectives,system optimal and user equilibrium,and the iterative process considers the actual displayable information constraints of the variable message screen to ensure that the guidance plan can be effectively conveyed through the variable message screen.Finally,taking the regional road network of Fuzhou as an example to illustrate the method,the travel time can be saved by 12.7%.
