Cal-ITP dataset ID crosswalk
Cal-ITP treats each realtime endpoint as its own dataset where Transitland holds vehicle positions, trip updates and alerts in one feed, so a feed often carries several ids.
Transitland Atlas tags feed records with Cal-ITP (Caltrans) identifiers as calitp_dataset_id, under CC-BY. Download the CSV or query through the GraphQL and REST APIs.
Showing the first 106 rows; the CSV has the complete crosswalk.
