On April 29, 2025, INRIX released their 25.1 map update. Based on the DEP team’s assessment, the update included roughly 4,226 new XD segments, and roughly 2,014 modified XD segments in Virginia. The DEP API real-time output using INRIX segments accounts for any newly added, removed, or modified segments. For users with access to the PDA API, data after April 29 will be reported using the new map. We expect to update the historical data to reflect the new map as much as possible by June.
