The invention provides an urban road traffic flow prediction method and device, equipment and a storage medium. The method comprises: for each road in the city, obtaining road characteristics of the road in a to-be-predicted time period, the road characteristics including the number of routes passing through the road in the city, the total length of the routes passing through the road in the city and the target initialization traffic flow transfer amount; the target initialized traffic flow transfer amount is a traffic flow transfer amount initial value determined for the road in advance; respectively inputting the road features of each road into a trained traffic flow prediction model to obtain each traffic flow prediction value of each road in the to-be-predicted time period; the traffic flow prediction model is a linear regression model. According to the method provided by the invention, the prediction efficiency of the urban road traffic flow is improved, and the computing resources of the server are saved.

    本申请提供一种城市道路车流量预测方法、装置、设备及存储介质。该方法包括:针对所述城市中的各道路,获取待预测时间段内所述道路的道路特征,所述道路特征包括所述城市中经过所述道路的路线数量、所述城市中经过所述道路的路线总长度和目标初始化车流转移量;所述目标初始化车流转移量为预先为所述道路确定的车流转移量初始值;分别将各道路的所述道路特征输入已训练好的车流量预测模型,得到所述各道路在所述待预测时间段内的各车流量预测值;所述车流量预测模型为线性回归模型。本申请的方法,提高了城市道路车流量的预测效率,且节省了服务器的计算资源。
