A traffic control plan details how vehicle and pedestrian traffic will be managed safely around a work zone.

A documented plan outlining signage, barriers, flaggers, detours, and other measures used to safely manage the flow of vehicles and pedestrians around a temporary work zone, protecting both workers and the public.
A road resurfacing crew implements a traffic control plan that includes lane closures, advance warning signs, and trained flaggers to safely direct traffic around the work area.
Traffic control plans are typically developed by a qualified traffic control supervisor or engineer, often in accordance with standards such as the Manual on Uniform Traffic Control Devices (MUTCD).
Common elements include signage placement, barrier and cone layouts, flagger positions, detour routes, and speed reduction zones tailored to the specific work being performed.
Requirements vary by jurisdiction and project scope, but most roadwork affecting public traffic — even short-duration work — requires some form of documented traffic control plan.
