摘　　要：针对城市路网交通流分布不均引起的交通拥堵问题,提出了在预约出行交通背景下基于预知OD的交通流路径优化方法。首先,分析了预约出行交通背景下预知OD的数据环境;其次,根据动态用户均衡准则,对预知的OD进行流量分配,给出预约出行车辆的路径;接着,使用预测控制的方法,结合路网上预约车辆的状态,以路网上路段的饱和度和未预约车辆的行程时间最小化为目标,从系统和用户两个角度对未预约车辆的路径进行实时的诱导,通过连续时域的滚动优化控制,优化交通流的路径;最后,对本方法的实现和应用做了思考和探索,对本研究做了总结。Aiming at the problem of traffic congestion caused by uneven distribution of urban road network traffic flow, a traffic flow path optimization method based on predictive OD under the background of travel reservation is proposed. First, analyze the data environment of predicted OD under the background of travel reservation;secondly, according to the dynamic user-equilibrium criterion, the predicted OD is distributed to give the route of the reserved vehicles;then, the method of predictive control is used in conjunction with the state of reserved vehicles, with the goal of minimizing the saturation of the road and the travel time of unreserved vehicles, real-time guidance of the path of unreserved vehicles from both the system and the user perspective, through continuous time domain rolling optimization control and optimize the path of traffic flow;finally, thought and explored the realization and application of this method, and summarized this research.
