Variable Signage Displays are used for displaying DYNAMIC content of TEXT and GRAPHICS to the public. They are widely, used for conveying current and advanced information of TRAFFIC to the road-users. Variable Signage Display systems can be installed at multiple locations of the same city or town and all these systems are supported with appropriate Data Communication Network (DCN). The content to all these displays can be sent from a central control room. At times, these displays are installed in specific routes of National or State level highways. They are also called as VMS displays (Variable Message Signage) displays.
