Supporting data for the manuscript "Dynamic Graph-Attention Traffic Network for Enhanced Urban Traffic Flow Prediction".

Taking center stage in current traffic flow forecasting research are the PEMS04 and PEMS08 datasets (planet.osm.org), which are derived from the California Transportation Management System's (Caltrans) extensive collection efforts of freeway induction coil detectors. These datasets not only provide traffic speed data updated every 5 minutes, but also meticulously record multi-dimensional information such as traffic flow and vehicle occupancy, reflecting real-time traffic conditions on some of California's key freeways.

This rich collection of data, which covers a diverse range of traffic flow patterns across seasons, weekdays, and holidays, provides researchers with valuable experimental materials to explore the complex dynamics of traffic flow.
