Practical Infrastructure Intelligence

Traffic-control documentation, digitized. Simple in the field. Powerful for safety.

Drive the closure. DTCD captures signs, lanes, GPS photos, and the route as you go — then builds the state-compliant daily diary your DOT expects and publishes your work zone to live federal-standard feeds.

The Problem

Critical infrastructure data is still trapped on paper.

Daily logs in clipboards. As-builts in screenshots. Permits in PDFs. Sign placements in someone’s memory. Every disconnected workflow means lost visibility, delayed decisions, and weak documentation when it matters most.

  • ✕Paper forms that never make it into the system of record
  • ✕Disconnected apps that don’t share data with each other
  • ✕Inconsistent records across crews, projects, and agencies
  • ✕Hours of office work to assemble what the field already knew
  • ✕No defensible record when a dispute or audit hits
The Solution

Capture once in the field. Use everywhere it matters.

Our software turns daily field activity into structured infrastructure data the moment it happens — ready for the dashboard, the public feed, the audit trail, and the next downstream system.

📱

Field-first capture

Native iOS & Android apps designed for the cab of a truck, not a desk.

🗂️

Structured data

Photos, MUTCD signs, GPS, certifications — all typed, validated, and queryable.

🌐

Open standards

WZDx, CWZ, CIFS, Datex II — native feeds, not proprietary lock-in.

🛡️

Defensible records

Time-stamped, GPS-anchored documentation built for audit, dispute, and discovery.

From Field to Feed

From Daily Diary to Real-Time Work Zone Data

Real-time work zone data starts with what happens in the field. DTCD captures closure type, location, lane impacts, start and end times, photos, inspections, deficiencies, and corrections in one structured workflow. The diary becomes the data source.

That same record can support WZDx-style feeds, 511 systems, work zone dashboards, traffic management centers, navigation providers, connected vehicle applications, corridor-level coordination, and AI-assisted safety review.

Reduce Traffic-Control Quantity Disputes

Traffic-control pay items are difficult to verify after the fact. Memory fades. Photos get lost. Spreadsheets disagree. DTCD documents — automatically, contemporaneously, with GPS and timestamps:

✓ What devices were installed
✓ Where they were placed
✓ When they were installed
✓ How long they were deployed
✓ Whether they were inspected
✓ Whether deficiencies were corrected
✓ Which records support payment
✓ Who approved the setup

Timestamped, GPS-tagged, photo-supported records help contractors and owners resolve questions in minutes — not weeks.

Field to Plan, Plan to Field

Improve Closure Setup Quality

DTCD helps document whether the traffic-control setup in the field matches the plan. Capture and review:

• Advance warning signs
• PCMS boards
• Arrow boards
• Drums and channelizers
• Tapers
• Buffer spaces
• Attenuators
• Temporary barrier
• Flagging stations
• Lane closure limits

Optional AI-assisted review can flag potential setup issues from field photos — decision-support only, not a compliance determination. Users must independently verify all AI-assisted output.

The Requirement Already Exists

Nearly Every State DOT Already Requires Daily Traffic-Control Records

A 50-state review found that nearly every state DOT requires some form of daily traffic-control record. The names — and how strongly each is spec-bound — differ: diary, daily inspection report, work-zone checklist, device record, project diary, logbook, daily work report. The underlying need is the same.

DTCD generates the right output for your state automatically. Tap any state below to see its specific form.
