A VMS board, or a Variable Message Sign, is a type of electronic sign that is used to display messages or other information to drivers or pedestrians. VMS boards are commonly used in transportation settings, such as on highways, roads, and at intersections, to provide real-time information about traffic conditions, construction, and other events that may affect travel.
VMS boards typically consist of a display panel with a matrix of LED lights or other display technology, along with a control system that allows the operator to change the message or display content remotely. VMS boards may be static, displaying a single message or image, or they may be dynamic, displaying different messages or images at different times.
VMS boards are often used in conjunction with other traffic control devices, such as traffic lights and barriers, to help manage and direct traffic flow. They are also used in emergency situations to provide important information or alerts to the public.
The cost of a VMS board depends on the size of the display, the quality of the display technology, and the features and capabilities of the control system
