Abstract
The invention relates to the field of spatio-temporal data mining or intelligent traffic, in particular to a traffic flow prediction method and device based on deep learning. The traffic flow prediction method comprises the following steps: receiving a flow prediction request sent by a user terminal; then, responding to the flow prediction request, and obtaining traffic flow information of a target road network corresponding to the target node identifier; acquiring spatiotemporal feature information based on the traffic flow information; and inputting the space-time feature information into aspace-time diagram convolution model to perform model prediction operation, and obtaining a flow prediction result, so that the influence of the spatial-temporal characteristics of the traffic flow ofthe whole road network on the traffic flow of the target node can be more comprehensively considered from the perspective of spatial-temporal correlation. The traffic flow prediction method and device based on deep learning can improve the accuracy of predicting the traffic flow of the road network.
Description
technical field [0001] The present invention relates to the field of spatio-temporal data mining or intelligent transportation, in particular, to a traffic flow prediction method and device based on deep learning. Background technique [0002] The interconnection in the field of transportation is the basis for realizing the interconnection of people flow, logistics, information flow and capital flow in urban agglomerations. A smooth road network in the metropolitan area is the most important thing in the infrastructure construction of the metropolitan area. The problem of traffic flow forecasting is crucial to constructing an intelligent highway network. In order to improve the operational capacity of the road network, improve people's travel efficiency, and reduce road traffic accidents, it is necessary to accurately predict the road traffic flow in advance and guide the traffic flow accordingly. [0003] On the other hand, with the construction and use of a large number ...
