The invention provides a data processing method and device for driving time prediction, equipment and a medium. The method comprises the following steps: acquiring a traffic characteristic graph and a road network data graph corresponding to a driving area; dividing and clustering the traffic feature map and the road network data map to obtain multiple types of traffic feature target maps and road network data target maps; determining a source domain and a target domain from the traffic characteristic target map and the road network data target map; training the graph convolutional network according to the data of the source domain to obtain an initial training model; and training the initial training model according to the data of the target domain to obtain a target training model.According to the method and the device, convolutional network training is performed on the historical driving trajectory and the road network data, so that accurate prediction of the mine car formation time is realized; therefore, a technical problem that tramcar travel time prediction cannot be carried out in an open-pit mine area in which driving characteristics and road network data are not obtained in the prior art is solved.

    本发明提供一种用于行车时间预测的数据处理方法、装置、设备和介质,通过获取行车区域对应的交通特征图和路网数据图;分别对所述交通特征图和所述路网数据图进行划分和聚类,以得到多类交通特征目标图和路网数据目标图;从所述交通特征目标图中和所述路网数据目标图中确定源域和目标域;根据源域的数据对图卷积网络进行训练,以得到初始训练模型;根据所述目标域的数据对所述初始训练模型进行训练,以得到目标训练模型,本发明通过对历史行车轨迹和路网数据进行卷积网络训练,实现了对矿车形成时间的准确预测,进而解决了现有技术无法对尚未获取行车特征和路网数据的露天矿地区进行矿车行程时间预测的技术问题。
