For Platforms, Maps & OEMs
Work-Zone Data, From the Source
DTCD data is generated by the crews who set the devices — not inferred from traffic, not keyed in the next day. Consume it free in every major standard, or take the premium low-latency V2X API.
Free Public Feeds
WZDx v4.2
GeoJSON, USDOT-registry listed.
CWZ 1.0

Stable endpoints at feeds.purposebuilt.systems — no API key required for testing and low-volume use.
Premium V2X API
10-second latency · API-key access
$99.99 per month
Built for connected-vehicle platforms, OEMs, and navigation providers: 10-second refresh, authenticated access, and enriched geometry including nested route polylines and sign-level detail. Live today — not a roadmap item.
Connected work-zone devices — arrow boards, portable message signs, smart signage — are linked to their parent work-zone events in a companion device feed, so equipment telemetry lands with documented context.
Upstream by design: maps, 511 systems, and connected-vehicle platforms are DTCD's downstream partners, not competitors. Our job is to make your work-zone layer true.
