AJEEVI VARIABLE  MESSAGE DISPLAY

VMDs are typically used to display information such as traffic conditions, travel times, weather conditions, and advertising messages. These displays are made up of an array of LEDs or other types of lighting elements that can be controlled individually, allowing for the display of dynamic content.

Typical messages provide the following information:

• Promotional messages about services provided by a road authority during non-critical hours, such as carpooling efforts, travelers’ information stations and 5-1-1 lines
• Crashes, including vehicle spin-out or rollover
• Road Works
• Incidents affecting normal traffic flow in a lane or on shoulders
• Non-recurring congestion, often a residual effect of cleared crash
• Closures of an entire road, e.g. over a mountain pass in winter.
• Exit ramp closures
• Debris on roadway
• Vehicle fires
• Wildfires
• Short-term maintenance or construction lasting less than three days
• Pavement failure alerts
• AMBER, Silver, and Blue Alerts, as well as weather warnings via the warning infrastructure of NOAA Weather Radio’s SAME system
• Travel times
• Variable speed limits
• Car park occupancy levels
• speed sign, for recommending a speed to approach the next traffic light in its green phase.
