Two datasets are available at Google Drive. If you use the data, please cite the following paper.

PeMS dataset (bay) is collected from PeMS and NYC dataset (nyc) is provided by Detecting Collective Anomalies from Multiple Spatio- Temporal Datasets across Different Domains. Each dataset consists of the following five datasets:
- data.npy
- node_subgraph.npy
- node_adjacent.txt
- time_features.txt
- node_dist.txt
where the data.npy is the traffic data in Bay area or New York City;
node_subgraph.npy represents the adjacency matrix of the subgraph of each node;
node_adjacent.txt represents all nodes in the subgraph of each node; time_features.txt represents the time feature of each time slots;
node_dist.txt represents the distance between nodes.
We also provide the information of the selected sensors in our paper, the file is vds_info.csv.
We have updated the ground truth of PeMS datasets. Note that we didn't delete the CHP incidents with duration<=0 since we extended the end time of each incident by 1 hour to include the impact of the traffic accidents. The ground truth of NYC dataset is provided by the authors of paper Detecting Collective Anomalies from Multiple Spatio-Temporal Datasets across Different Domains.
If you need anomaly labels for other times, please refer to CHP incident and LCS Report. I hope they will be helpful to you.
