A variety of roadside technologies, such as dynamic messages signs and highway advisory radio, can be used to provide travelers with weather-related travel information. Weather specific internet sites and phone information lines may also be implemented. ITS operators may also send information to in-vehicle devices capable of displaying traveler information. Coordination with regional or multimodal traveler information efforts like 511, as well as arterial, freeway and incident management programs, can increase the availability of information on weather conditions along roadways.
