VMS Mast
A Variable Message Sign (VMS) is a traffic control device that allows its message to be changed manually, electrically, mechanically, or electromechanically. It is used to display information about traffic congestion, traffic accidents, construction and maintenance work, adverse weather conditions, road conditions, planned events and occasions, and other possible situations or road facilities, such as movable bridges, toll booths, weigh stations, and more.
Variable Message Signs, commonly referred to as VMS, are traffic control devices used for real-time driver information. They are installed in various configurations, including gateway-style, on VMS masts along road shoulders, or as cantilevered structures over roadways. The messages on these signs are generally displayed in real-time, with information controlled and transmitted from a central system or locally. VMS systems are designed to influence driving behavior and improve traffic flow and operations.
