The original dataset from Diffusion Convolutional Recurrent Neural Network: Data-Driven Traffic Forecasting contains 6 months of traffic readings from 01/01/2017 to 05/31/2017 collected every 5 minutes by 325 traffic sensors in San Francisco Bay Area. The measurements are provided by California Transportation Agencies (CalTrans) Performance Measurement System (PeMS).

The Point missing setting, introduced in Filling the G_ap_s: Multivariate Time Series Imputation by Graph Neural Networks, is a variant for imputation in which 25% of data are masked out uniformly at random. Results on this dataset are assumed to be obtained in-sample, meaning that the test interval is used also for training, excluding data used for evaluation.
