Abstract

The influence of road surface conditions on traffic accidents is remarkable, especially in snowy countries. And accidents caused by polished ice on the surface of roads are still serious problem in winter. A remote sensing method for road surface conditions will be effective for the reduction of accidents. In this paper an NIR spectroscopic method was applied for the various roads whose surfaces were covered in ice. And the possibility to detect a road friction coefficient precisely by using around 1500 nm wavelength incident light at 60 degree reflection angle was obtained.
