From Coarse to Fine: Managing Temporal Granularity in Spatio-Temporal Data for Fine-Grained Traffic Prediction

Researchers propose STRP, a machine learning framework that predicts fine-grained traffic patterns from coarse-grained historical data, addressing a critical mismatch between how traffic data is stored and how it needs to be used. The solution combines tree convolution and inverse dilated convolution to efficiently model spatial and temporal dependencies, outperforming existing approaches while reducing computational overhead.
