Variable Message Signs (VMS) are one of the key elements of dynamic traffic management systems. Depending on the traffic situation, VMS inform, warn, and guide the motorists on highways, expressways and arterial roads of cities by displaying route /rerouting information, warnings (accidents, congestions), toll rates and special information. VMS is a critical element of Intelligent Traffic Management Systems (ITMS)
- informing motorists about current traffic conditions warning about threats
- suggesting detours in the event of traffic problems
- directing to the right lane on the highway
- informing about road conditions
- informing about free parking spaces
Variable Message Signs (VMS) can cooperate with devices for measuring traffic and weighing vehicles in motion, with speed measurement radars and with weather stations, automatically displaying information. The signs can also be controlled from one central location – the main traffic management unit.
The device complies with European standards and guidelines for variable content signs EN 12966.
