The invention provides a method for predicting a main traffic flow path and a model training method, and relates to the technical field of artificial intelligence, in particular to the technical field of intelligent traffic, road traffic management and navigation. According to the implementation scheme, a plurality of traffic flow paths in a preset area in a historical time period are acquired; splitting each route in the plurality of routes into at least one sub-road section; for each sub-road section, based on the sub-road section, obtaining at least one sub-traffic flow path corresponding to the sub-road section and first traffic data of each sub-traffic flow path; based on the first flow data of each sub-traffic-flow path, predicting a flow prediction value of each sub-traffic-flow path in a future time period; determining a first prediction sub-path corresponding to the sub-road section based on the flow prediction value of each sub-traffic flow path; and executing sub-path splicing based on the plurality of first prediction sub-paths corresponding to the plurality of sub-road sections in the plurality of routes so as to obtain a main traffic flow path prediction result.

    本公开提供了一种用于预测主要车流路径的方法及模型训练方法,涉及人工智能技术领域,尤其涉及智慧交通、道路交通管理及导航技术领域。实现方案为:获取历史时段内的预设区域内的多个车流路径;将多个路线中的每个路线拆分为至少一个子路段;针对每个子路段:基于该子路段,获取与该子路段相应的至少一个子车流路径以及每个子车流路径的第一流量数据;基于每个子车流路径的第一流量数据,预测得到未来时段内每个子车流路径的流量预测值;以及基于每个子车流路径的流量预测值,确定该子路段对应的第一预测子路径;以及基于多个路线中的多个子路段相应的多个第一预测子路径,执行子路径拼接,以获得主要车流路径预测结果。
