The surface freezing and snowfall on the highway and bridge deck will be a cause of major accident in winter. The accident can be effectively reduced by preventing the road surface freezing and snowfall. For these, it is needed that the evaluation method for perception of the road surface condition. In this study, the detection system was investigated using the contact and contactless sensors. From the results, it is seemed that the organized system could well predict the road surface condition and so on.
