Traffic Control and Transportation Management Plans

The traffic control plan is the approved blueprint for how road users move through each phase of the work. Larger projects add a transportation management plan. This is where planning becomes an enforceable, field-ready document.

Last reviewed: June 24, 2026

Why It Matters

  • The approved plan is the standard the field setup is measured against — inspectors check the work zone against it, and deviations must be authorized.
  • A clear, complete plan is what turns a good intention into a compliant, buildable work zone.

When It Applies

  • For any work in the public right-of-way that affects traffic, pedestrians, or bicycles; the plan's complexity scales with the work.

Planning Considerations

  • A traffic control plan (also called a temporary traffic control plan) shows advance warning, transitions, the activity area, buffers, and how each road user is guided through each phase.
  • Larger or higher-impact projects may require a transportation management plan or maintenance-of-traffic plan, plus pedestrian routing, detour, and phasing plans and, for worker movement, an internal traffic control plan.

Field Considerations

  • The field setup must match the approved plan. Where conditions differ, a revision or authorized deviation is required rather than an informal change.
  • Plan revisions are documented and re-approved so the field and the record stay in sync.

Inspection Considerations

  • Inspectors compare the installed setup against the approved plan and note any deviation for correction.
  • The current approved plan (and any revisions) should be available on site.

Common Compliance Failures

  • Field setup that does not match the approved plan.
  • Using an outdated plan revision after conditions or phasing changed.

Upstream Prevention

  • Design the plan around verified existing conditions and buildable phasing so the field can follow it.
  • Route changes through formal revision and re-approval, and keep the current plan on site.

Frequently Asked Questions

What is a traffic control plan?

It's the approved blueprint for guiding vehicles, pedestrians, and bikes safely through or around a work zone in each phase — advance warning, transitions, the activity area, and buffers. The field setup is expected to match it.

What is the difference between a TCP and a TMP?

A TCP (or TTCP) details the traffic control setup for the work. A TMP is a broader plan for larger or higher-impact projects, also covering mobility, public information, and incident management. Requirements for each come from the governing agency.
