This paper relates to the study of the road surface condition detection technique based on the image taken by TV camera attached to the rearview mirror of a vehicle. We examine a technique to detect features related to water and snow on the road surface, in which the detection was stably possible throughout day and night. The extraction of the water on the road is made with the technique which gets the property of the polarization from the image. And the extraction of the snow on the road is made with the texture analysis. We conducted field tests to verify the detection ability of the road surface condition while running on the expressway at 100km/h on the average and obtained a favorable result.
