Better road traffic management

Variable Massages Signs (VMS) by Microprocessador Sistemas Digitais, SA Portugal give travellers information about special events. Such signs warn of traffic congestion, accidents, incidents, weather and road conditions information, roadwork zones or speed limits on a specific highway segment. They may also ask vehicles to take alternative routes, limit travel speed, warn of duration and location of the incidents or just inform of the traffic conditions.
