As of December 10, 2024, the DEP API now includes two new endpoints (/rm3p/dep_inrix_tmc and /rm3p/dep_inrix_xd) that provide a full complement of INRIX data available to DEP. These new endpoints, defined and described in the API Reference Documentation, provide a superset of data currently available in the old INRIX API endpoints. The old endpoints (/rm3p/dep_speed_tt_tmc and /rm3p/dep_speed_tt_xd) will be deprecated and decommissioned on March 1, 2025. If you are currently using these old endpoints, please plan to switch to the new endpoints before March 1, 2025.

On November 1, 2024, the DEP API output includes the Fredericksburg Regional Transit (FXBGO) alerts.

On October 24, 2024, the DEP API output includes a new set of CCTV stream agency filters to enable more precise filtering capabilities. The new filters are as follows:

• [vdot] = VDOT cameras from ATMS – Arlington CCTV – Alexandria CCTV
• [arlingtonva] = Arlington CCTV
• [alexandriava] = Alexandria CCTV
• [vdot_rm3p] = [vdot] + [arlingtonva] + [alexandriava] with duplicates removed.

On August 15, 2024, AMTRAK GTFS feed was added to the DEP API output as well as the specification-confirming GTFS feed.
