Embodiment approach
[0033] Such as figure 2 As shown, the road flow prediction method based on graph convolution analysis provided by the embodiment of the present application, an implementation thereof, includes the following steps:
[0034] Step 202: Determine the node for predicting the traffic service, and collect the characteristic value of the node.
[0035] Step 204: preset a loss function, use the feature value as input data to train the model, and obtain model parameters.
[0036] Step 206: Predict the flow of the node according to the model parameters and the input data.
[0037] The road flow prediction method based on graph convolution analysis provided by the embodiment of the present application can accurately predict subsequent flow data according to the connection relationship between road nodes by inputting the known road network connection structure and short-term historical flow data. Effectively predict the impact of unexpected events on traffic, so as to take effective cou...
