Does Hawaii require a daily traffic control diary?

Hawaii DOT requires traffic-control documentation on work zones, and many projects call for a daily traffic-control diary or inspection report. The Digital Traffic Control Diary (DTCD) produces a GPS-tagged, photo-backed daily record aligned to the Hawaii DOT documentation workflow.

What should a Hawaii traffic control diary include?

Typically the date, the devices placed and removed with their locations and times, inspections, any deficiencies and corrections, and the personnel on site. DTCD captures all of this automatically with GPS, photos, and timestamps, and exports it as a PDF or WZDx/CWZ feed.

Is there an app for Hawaii traffic control documentation?

Yes. DTCD (Digital Traffic Control Diary) creates Hawaii-ready daily diaries, inspection reports, GPS-tagged photos, and live WZDx / CWZ feeds — replacing paper diaries and clipboards for contractors and DOT inspectors.

Hawaii DOT — Section 645 Work Zone Traffic Control

The Hawaii DOT Requirement

Hawaii Department of Transportation contract specifications and construction-manual guidance require traffic-control documentation as a standard contractor deliverable. The naming and form vary by state; the underlying requirement — a date-stamped, contemporaneous record of traffic-control activity — is the same nationwide.

HDOT's Standard Specifications Section 645 (Work Zone Traffic Control, as amended by current special provisions) governs temporary traffic control — traffic control plans due 15 working days in advance, strict lane-closure hour limits, and police officers at closure locations; documentation requirements are set per contract special provision.

How DTCD applies to this: Countable as project-specific daily traffic-control documentation; pair with HDOT Section 645 Work Zone Traffic Control as statewide TTC framework.

How DTCD Satisfies Hawaii's Requirement

Daily Diary Output

One-tap PDF generation produces a date-stamped, GPS-tagged traffic-control diary suitable for submission to Hawaii DOT inspectors. Output cites the controlling spec by name on every page.

MUTCD Sign Recognition

AI-assisted MUTCD code identification on every captured photo. Begin-zone, end-zone, taper, and device placement automatically catalogued. Decision-support only — verify all output.

Personnel and Device Logging

Flagger hours, pilot-car hours, connected-device status (arrowboards, PCMS), and per-day deficiency notes — captured in the field, summarized automatically.

WZDx Feed Generation

Real-time WZDx v4.2 / CWZ v1.0 feed publication for any closure. Connected-vehicle platforms, navigation apps, and Hawaii's 511 system can ingest the same data your diary cites.

The PDF below is a sample DTCD-generated traffic-control diary — the same format your inspector receives, customized to cite the controlling spec for the project's state. Every entry is GPS-tagged, timestamped, and photo-supported.

Why Hawaii Contractors Use DTCD

Hawaii contractors face the same documentation burden every day: capture photos, log devices, track personnel hours, generate the diary, file with the inspector. DTCD compresses that burden into a single mobile workflow. The output PDF cites Hawaii's Section 645 Work Zone Traffic Control requirement by name — so the inspector sees exactly the format they expect, the contractor keeps a complete record, and nothing falls through the cracks.
