According to the MPC-based upstream dynamic shunting method under the highway abnormal event, the model can better understand, capture and predict the traffic condition of the road section through ETC data, vehicle track data and road section attributes. The invention provides a method for establishing a high-speed METANET macroscopic traffic flow model and designing an MPC upstream shunt flow control scheme for solving the problems that the research on traffic guidance shunt under the highway abnormal event is less, the existing research does not consider the cooperative influence of the upstream multi-section flow on the abnormal accident road section, and the upstream multi-section coordinated dynamic shunt control scheme cannot be formed, and aims at solving the problems that the construction of the high-speed METANET macroscopic traffic flow model and the MPC upstream shunt flow control scheme are provided. The traffic state is monitored and predicted in real time and is fed back to the MPC controller as input, a dynamic upstream shunting scheme is formed, the shunting amount can be dynamically adjusted when necessary, and efficient operation of the whole traffic system is guaranteed. According to the invention, support can be provided for traffic management personnel to organize emergency traffic, and the traffic capacity and service level of the expressway are improved.
本发明提出了一种基于MPC的高速公路异常事件下的上游动态分流方法,通过ETC数据、车辆轨迹数据和路段属性,使模型能够更好地理解和捕获预测路段的交通状况。本发明针对高速公路异常事件下的交通诱导分流研究较少,已有研究没有考虑上游多路段流量对异常事故路段的协同影响,无法形成上游多路段协调动态分流控制方案,提出建立高速METANET宏观交通流模型,设计MPC控制上游分流量方案,对交通状态的实时监测与预测,同时作为输入反馈回MPC控制器,形成动态的上游分流方案,并能在必要时动态调整分流量,保障整体交通系统的高效运行。本发明可以为交通管理人员组织应急交通提供支撑,提高高速公路通行能力和服务水平。
