A Variable Message Sign (VMS) is an electronic sign that is used to display dynamic, changeable messages to drivers or pedestrians. They are often used on highways, roads, and in other transportation-related settings to provide real-time information such as traffic conditions, construction updates, and weather warnings.
VMS boards can be controlled remotely and can display a variety of messages, including text, graphics, and images. They are highly customizable and can be programmed to display different messages based on the time of day, weather conditions, or other factors.
The VMS can be of different type like:
Full-Matrix VMS: These signs have a high resolution and can display text, graphics, and images. They are typically used for more complex messages and can display multiple lines of text at once.
Modular VMS: These signs are made up of individual LED modules and are often used for more basic messages. They are typically less expensive than full-matrix signs and are often used for displaying simple text or symbols.
Portable VMS: These signs are designed to be easily transported and are often used for temporary traffic control and construction projects.
VMS boards are increasingly being used in urban areas, such as on public transportation, in shopping centers, and in other public spaces to provide real-time information and advertising.
