The Highway Advisory Radio with Road Weather Information System (HARWIS) from MH Corbin adds a new level of flexibility to Highway Advisory Radio Systems. Available as a complete system or as an upgrade to existing systems, the HARWIS can detect weather conditions using pavement, atmospheric, and visibility sensors.

HARWIS can provide the motorist with alerts for low visibility conditions, high winds, sleet, snow, slippery ice and heavy rain via HAR, VMS, flashing beacons, or text messaging.

Data is collected from in-ground pavement analyzers and smart weather sensors by Lufft®. Data is reported using the MH Corbin Digital Communications Controller.
