Road traffic control device

These devices are made with retroreflective materials that reflect light from headlights back towards the driver's eyes.

Permanent VMS displays are mounted on large sign structures overhead or alongside the road.

Channelizing devices are used to warn drivers and pedestrians and to guide them through a work zone.

They are used to guide and channel traffic by designating lanes and indicating stopping points at intersections.

They are used along the shoulders or centerlines of highways to alert drivers that they are leaving their traffic lane.
