Traffic Incident Management > Information Dissemination > Dynamic Message Signs
Organizations operating ITS can share information concerning ongoing incidents with road users through technologies deployed as part of incident management programs, such as dynamic messages signs or highway advisory radio. ITS operators may also send information to in-vehicle devices capable of displaying traveler information. Coordination with regional or multimodal traveler information efforts, as well as arterial and freeway management programs, can also increase the availability of incident-related information.
