When construction, maintenance and special events suspend or interrupt the normal function of the roadway, a traffic control plan is developed to ensure the safety of all road users, and the protection of workers. The plan shows how traffic is to be safely separated from workers at the worksite or work route. It is an instruction for the site/road crews and is usually in the form of a diagram showing the road conditions (lanes, signs etc.) and how the traffic is to be managed around the site / activities (temporary signs, posting of traffic control staff, etc.).
Traffic control plans (TCP’s) are detailed drawings that show the layout of temporary road signs and devices to warn and guide traffic past, around and through the work site safely. A TCP adheres to the principles outlined in the Manual for Uniform Traffic Control (MUTCD) & guidelines which have been outlined by the State.
