Drive the closure. DTCD captures signs, lanes, and GPS photos as you go, then builds the state-compliant daily diary your DOT expects and generates your invoice from the same data. What took an hour at the kitchen table now takes the drive-through.

This is the actual PDF diary DTCD generates from a drive-through, and the invoice built from the same closure data. No mockups. Open them.
Road-snapped map, GPS-stamped photos, device log, daily entries. The document your DOT inspector expects.
Open the sample diary (PDF) →Line items generated from closure data. No spreadsheets, no double-entry, no reconstructing quantities from memory.
Open the sample invoice (PDF) →Every DTCD closure publishes to the same WZDx feed 511 systems and navigation apps consume. Listed in the USDOT federal registry.
View the live feed →Daily logs on paper. Photos scattered across three phones. Quantities reconstructed from memory at invoice time. When a pay item gets questioned eight months later, the argument isn't decided in the field. It's decided by whoever has the better paper. Right now, that's usually nobody.
AI-assisted MUTCD sign detection captures your setup as you drive the closure. Decision-support only; you verify the output.
GPS, lane configuration, and closure type auto-fill from what it saw. Add photos and notes if you want them.
State-compliant PDF diary with map, photos, hours, and entries. Invoice line items from the same data. Submit both before you are back at the yard.
Traffic-control quantities are hard to verify after the fact. Memory fades, photos get lost, spreadsheets disagree, and the contractor without records eats the difference. DTCD documents everything contemporaneously, automatically:
What was installed. Where it was placed. When it went up and came down. Whether it was inspected. Whether deficiencies were corrected. Who approved the setup.
Timestamped, GPS-anchored, photo-supported. When a quantity gets questioned, you answer in minutes with records, not in weeks with reconstructions.
How to keep a record that holds up in a dispute →This map is the live WZDx 4.2 / CWZ 1.0 feed DTCD publishes to the USDOT federal registry. Every marker is a real active closure entered by a real crew. No screenshots, no demo data. What you see is what 511 systems and connected vehicles consume.
MUTCD signs identified during the drive-through.
Every photo stamped, timestamped, and cloud-synced.
Road-snapped map, photos, logs, and entries in seconds.
Line items built straight from closure data.
The live feed moves with striping and mowing crews. Only on DTCD.
Two-way communication with DOT inspectors built into every closure.
Plus certification-expiry tracking, a lock-screen closure timer, and multi-format export (WZDx, KML, invoice-ready). See the data platform →
A 50-state review found nearly every state DOT requires some form of daily traffic-control record. The names differ: diary, daily inspection report, work-zone checklist, daily work report. DTCD generates the right output for your state automatically. Tap your state to see its spec.
DTCD is new, and we're saying so. The first ten traffic-control contractors get:
In exchange, you help shape the product and, if it earns it, tell us so publicly.
