Some travel information dissemination strategies include: variable message signs (VMS), highways advisory radio (HAR), radio broadcast, cable television (CATV), personal computers/modems, interactive information kiosks, and real-time-dial-in telephone systems. Information is disseminated on traffic conditions, alternative routes, adverse weather and driving conditions, construction zones, and special lane use.
