Descripton

Highway advisory radios (HAR) are licensed low-power AM radio stations set up by the Ohio DOT to provide information regarding traffic conditions, travel times, construction, road incidents, missing persons, and other information deemed relevant to motorists. Roadside signs for HAR and the correct AM frequency include flashing beacon lights that provide for traffic alerts when the beacons are activated. HAR sites are designed to be automated so that when travel times increase by a pre-determined amount for a particular section of roadway, the HAR will provide travel-time information for that particular section of roadway only.
