Moving Operations, Published Live

Striping, sweeping, mowing, crack-sealing — work zones that travel down the road at walking speed, invisible to every planning-based system and crowdsourced map. DTCD is built to publish them.

The Most Dangerous Work Zone Is the One That Moves

A static lane closure appears on 511 because someone planned it. A striping crew doesn't — it appears around a curve at 8 mph with a truck-mounted attenuator between the crew and traffic. No planning system can publish what changes minute by minute. A crew-carried app can.

How It Works

Current position
The operation's live location updates as field GPS positions advance — published into the CWZ mobile-operations feed.
Projected route
Downstream consumers see where the operation is headed — the roadway ahead of the crew, where warnings matter most.
Workers present
Opt-in worker-presence signals populate the feed's workers-present field, giving connected vehicles and navigation the strongest reason to slow traffic down.

Standards-Native

Mobile operations publish through the same CWZ 1.0 / WZDx feeds as static closures — typed, machine-readable, and listed in the USDOT Work Zone Data Feed Registry. If your platform consumes work-zone data, moving operations arrive in the schema you already parse.

How DTCD Maps to 23 CFR 630 — Subparts J & K

DTCD's role across the rule is to document, monitor, and publish — it produces the evidentiary record each provision leans on. It doesn't place devices, supply barriers or attenuators, train workers, or make the compliance determination; those stay with the contractor and agency.

What the rule calls forCiteHow DTCD supports it
Subpart J — Work Zone Safety & Mobility
Work-zone impact monitoring§630.1008, .1014Produces the contemporaneous, GPS- and time-stamped daily diary and day/night inspection log that is the monitoring record.
Trained personnel, on record§630.1008Captures each crew member's traffic-control certification (TCS / flagger), tracks renewal dates, and ties the certified worker to the closure they worked — the trained-personnel record the rule asks for, and the roster that stands behind the workers-present signal DTCD publishes to its CWZ feed.
Biennial process review§630.1008Every closure is retrievable on demand behind a tamper-evident audit trail, so a reviewer can pull a project's full history without a paper chase.
TMP — Temporary Traffic Control§630.1012Documents the devices actually deployed against the plan and MUTCD typical application.
TMP — Public InformationOnly DTCD§630.1012Turns the same field capture into a live, published WZDx / CWZ feed on the USDOT registry that 511 systems, mapping partners, and navigation apps source from — the work zone reaches the map in real time, automatically.
Subpart K — Temporary Traffic Control Devices
Device condition & placement§630.1108, .1110Per-device photo capture; on-device AI flags missing, damaged, or misplaced signs and channelizing devices.
Positive protection deployed§630.1108Documents that barrier, crash cushion, or attenuator was in place, and flags when positive protection appears absent for exposed workers. DTCD records and monitors; it does not supply the hardware.
Mobile operations & the shadow vehicleOnly DTCD§630.1108Moving Operations captures the traveling work zone live — position, projected route, workers present — that no planning-based system can see, and produces the record that the shadow vehicle / TMA was trailing the crew. This is how you document the mobile-operation protection Subpart K calls for.
Worker exposure control§630.1108Opt-in worker-presence pings record who was on foot inside the zone, and when.
Flagging & law-enforcement measures§630.1108Documents flagger stations and checks for the STOP/SLOW paddle and advance flagger warning (W20-7).
Device maintenance§630.1110The inspect-and-correct trail records each deficiency found and the re-check that closed it out.

DTCD supports compliance with these provisions by producing and maintaining the required records and the standards-based data feed; it does not replace trained personnel, temporary-traffic-control device placement, or positive protection.
