Dynamic Message Signs (DMS) use active, changeable displays to enhance roadway safety as part of an intelligent transportation system (ITS). An ITS does not always have to be a large, complex, and expensive system. Sometimes a single DMS with warning lights or a driver feedback display can make a positive difference when strategically applied. DMS are very conspicuous by their active and attention capturing nature and are best applied as a roadway safety enhancement at high-hazard locations or at high priority speed violation locations.
