Patrik Jonsson from Combitech held a lecture on a new measurement technique that can determine if a road is wet, dry , icy or covered with snow. The intention is to efficient ice control and avoids accidents.

This huge road accident at the bridge in Åstorp last year with many casualties and one death had probably been avoided if the bridge paving was monitored with Patrik’s technology. At the lecture Patrik will present more about the measuring technique that uses spectral analysis of infrared light reflected in the roadway. The result of this analysis is a picture of the roadway where the various parts of the roadway classified as icy, wet, dry or snowy.
