Article summary:
1. This article proposes a spatial interaction graph convolutional network model to predict missing spatial origin-destination flows.
2. The model utilizes geographical unit embedding in local spatial networks to improve prediction accuracy.
3. Experiments on Beijing taxi trip data verified the usefulness of the model in predicting flow data, and showed that more attributes of geographical units, a more proper negative sampling rate and a larger training set can increase the prediction accuracy of flow data.
