Non-invasive measuring principle

The optical (spectroscopic) measuring principle delivers the important road surface condition parameter without the need of construction works on the road itself.

Representitive measurement of the road condition

Road condition is evaluated over a representive spot area of the road surface of >2 sqm.

High-quality road condition parameters for comprehensive description

Sensor measures on multiple wavelengths in the infrared optical range and delivers important road information: surface temperature, water film height, ice layer thickness, ice percentage, freezing temperature, road condition index, friction and snow height.
