New measurement technologies to save lives on the roads – evertiq.se

Patrik Jonsson, who will defend at my University during the day, presents a completely new measurement technology that can determine whether a road is wet, dry, icy or snow-covered. This, he hopes, will help save lives.

The icy and snowy roads contribute to numerous traffic accidents in our cold country should not be a surprise. To combat slipping in use today a system that measures the road surface on individual points or over very small areas. You also get a large margin of error. Patrik Jonsson, industrial at Mid Sweden University research center STC, has developed a new measurement technique without contact can distinguish areas on the road as dry, wet, icy or snowy. The system is unique in that it also detects small differences in road conditions such as may occur in the wheel tracks and cause problems in overtaking.

– A commercial sensor has been developed based on the research results. It has received considerable attention at international conferences and from road authorities, especially in the Nordic countries. Norway, Denmark and the Czech Republic will test the system during the coming winter, says Patrik Jonsson.

The system consists of a camera based on spectral analysis of images taken in infrared range (NIR). That along with analysis models and measurement data from the Swedish Transport Administration’s weather stations gives a picture of the roadway where different parts of the road may be classified as icy, wet, dry or snowy.

Now, Patrik to return to his post at Combitech AB, where the currently is to define how the company can best benefit from Patrik’s skills.

– Although research has shown successful results, there are opportunities for improvement of the system. The plan is that I continue to be included in research groups between Sweden and Norway, as Combitech and Mittuniversitetet collaborating in new research concludes Patrik.

The research was funded by Combitech AB, Saab AB, Klimator AB and the Swedish Transport Administration in cooperation with the Mid Sweden University.
