Traffic Dataset

PEMS03, PEMS04, and PEMS08: These datasets are collected from the California freeway performance measurement system (PEMS), with a sampling interval of 5 minutes. Their time spans are 3 months, 2 months, and 2 months, respectively. PEMS03 contains only the traffic flow feature, while PEMS04 and PEMS08 include three features: traffic flow, speed, and occupancy. Seattle: This dataset is collected from the Seattle traffic system, covering a period of one year. The data are processed into an hourly (1-hour) interval, and include traffic flow, speed, and occupancy. These datasets are widely used in traffic forecasting tasks, including spatiotemporal modeling of node-level traffic flow, speed, and occupancy.
