District Department of Transportation (DDOT) — Public Space Permit Traffic Control

District of Columbia Traffic-Control Documentation

DTCD generates daily traffic-control documentation aligned with the District of Columbia's DDOT Public Space Permit and Traffic Control Plan requirements. iOS, Android, and web — built for contractors and utility operators working in DC's public right-of-way under District Department of Transportation regulatory authority.

The DDOT Requirement

Work performed in the District of Columbia's public right-of-way — utility installations, roadway construction, sidewalk repair, scaffolding, lane closures — requires a DDOT Public Space Permit. The permit conditions include an approved Traffic Control Plan (TCP) and field maintenance of traffic (MOT) consistent with the national MUTCD as adopted and supplemented by DDOT.

DDOT's Design and Engineering Manual sets traffic-control requirements for work in DC's public space; permit holders must implement the approved Traffic Control Plan and maintain it for inspection during the duration of work.

How DTCD applies to this: DTCD produces the contemporaneous, photo-supported, GPS-tagged daily record that backs your DDOT Public Space Permit — TCP setup, MOT changes, sign placement, flagger activity, and end-of-day clearance — in the format inspectors expect to review.

How DTCD Supports DC's Requirement

Daily Diary Output

One-tap PDF generation produces a date-stamped, GPS-tagged traffic-control diary. Every page cites the controlling agency (DDOT) and the underlying federal MUTCD reference, so DDOT inspectors and project owners see exactly the format they expect.

MUTCD Sign Recognition

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

Personnel and Device Logging

Flagger hours, pilot-car hours, connected-device status (arrow boards, PCMS), and per-day deficiency notes — captured in the field, summarized automatically for permit close-out.

WZDx Feed Generation

Real-time WZDx v4.2 / CWZ v1.0 feed publication for any closure. The District of Columbia 511 system, connected-vehicle platforms, and navigation apps can ingest the same data your diary cites — DTCD is listed on the USDOT Work Zone Data Exchange registry.

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 DC Contractors Use DTCD

Work in the District's public right-of-way carries an unusually high documentation burden: DDOT permit conditions, federal agency tenants, historic-district overlays, and federal monument-area restrictions can each generate their own inspection touchpoints. DTCD compresses that burden into a single mobile workflow — capture once, generate the daily diary, publish the federal feed, and keep the contemporaneous record DDOT inspectors expect.
