The embodiment of the invention provides a traffic distribution method and system based on multi-source data. The method comprises: acquiring part of road section multi-source traffic data collected by a multi-class detector in a to-be-distributed area; inputting the multi-source traffic data of the part of road sections into a dynamic O-D backstepping and traffic distribution combined model, andobtaining full-road-section target flow data and full-path target flow data in a to-be-distributed region, so as to realize traffic distribution; the dynamic O-D backstepping and traffic distributioncombined model being a single-layer combined model formed by dynamic network loading and traffic flow mathematical description based on the dynamic O-D backstepping model and the dynamic traffic distribution combined model. According to the embodiment of the invention, the multi-source data and the dynamic OD backstepping and traffic distribution combination model are effectively fused, the dynamic traffic volume of the whole road section can be solved based on the obtained multi-source data of part of the road sections, efficient and deep utilization of traffic big data is realized, and the efficiency of traffic planning and management control work is improved.

    本发明实施例提供一种基于多源数据的交通分配方法及系统,该方法包括:获取待分配区域内的多类别检测器采集的部分路段多源交通数据;将该部分路段多源交通数据输入至动态O‑D反推与交通分配组合模型中,获取到待分配区域内全路段目标流量数据和全路径目标流量数据,以实现交通分配;动态O‑D反推与交通分配组合模型是基于动态O‑D反推模型和动态交通分配组合模型通过动态网络加载以及交通流的数学描述而成的单层组合模型。本发明实施例通过将多源数据与动态OD反推以及交通分配组合模型进行有效融合,可以基于获取的部分路段多源数据求解得全路段的动态交通量,实现了对交通大数据的高效深度利用,提高了交通规划和管理控制工作的效率。
