The invention provides a vehicle driving track deduction method for a large-area monitoring blind area, and belongs to the technical field of intelligent traffic, and the method comprises the steps: firstly positioning a starting point road section and a terminal point road section of a target vehicle, and then determining a structure of a Bayesian network by referring to a traffic road network topological relation; in combination with real-time traffic data such as vehicle speed, traffic flow and road width, influence factors are quantified, probability values of each father node and each child node are calculated, and then Bayesian network parameters are obtained. Then, effective connection of road sections in the road network structure is achieved by selecting the road sections corresponding to the nodes with the high probability values, and finally target vehicle driving track deduction from the starting point to the ending point is completed. According to the method, the real driving track of the vehicle in the large-area monitoring blind area is highly restored, and the collaboration degree of various traffic data is improved.
本发明提供了一种面向大面积监控盲区的车辆行驶轨迹推演方法,属于智慧交通技术领域,本发明首先定位出目标车辆的起点与终点路段,再参考交通路网拓扑关系确立贝叶斯网络的结构。结合实时的车辆速度、车流量、道路宽度等交通数据,并量化影响因子,计算每个父节点与子节点的概率值,进而得到贝叶斯网络参数。随后,通过选择概率值较高的节点所对应的路段,实现路网结构中路段的有效连接,最终完成从起点至终点的目标车辆驾驶轨迹推演。本发明高度还原了大面积监控盲区中车辆真实行驶轨迹,提高了各类交通数据的协同程度。
