Traffic-control equipment marks boundaries, creates barriers, and provides direction for managing traffic on roads and inside facilities. These traffic safety products help prevent collisions and traffic backups. Barrier tapes and pavement markers identify closed off areas, traffic lanes, survey sites, and more. Traffic barrels, drums, barricades, cones, and delineator posts form temporary lanes and block sections of road during road construction. Parking curbs, speed bumps, and stop/slow paddles help control traffic speed and flow. Traffic warning flags alert people to truck traffic hazards such as wide loads and nearby vehicles. Windsocks alert pilots and air traffic controllers to wind direction and speed and are used in industrial setting to indicate wind direction in the event of a gas or chemical leak.
