Results for tag: "Variable Message Sign"

Variable Message Signs (VMS) are electronic signs used to display text messages, images, and symbols to drivers and pedestrians. They are typically used to provide real-time information such as traffic conditions, road closures, and weather warnings. VMS are typically composed of a display panel, a controller, and a power supply. The display panel is typically composed of light-emitting diodes (LEDs) or liquid crystal displays (LCDs). The controller is responsible for controlling the display panel and can be either a dedicated computer or a programmable logic controller (PLC). The power supply is responsible for providing the necessary power to the display panel and controller. VMS are used in a variety of applications, including traffic management, public safety, and advertising. They are often used in conjunction with other traffic control systems, such as traffic cameras and traffic sensors. VMS are also used in public transportation systems, such as airports and train stations, to provide real-time information to passengers. Some companies in the VMS market include Daktronics, Transign, and Optec Displays. Show Less Read more
