Abstract
The future autonomous driving vehicles strongly require to understand road surface weather condition to realize their robust operation in cold weather districts. There is a technology to obtain the qualitative road condition, the vehicles would also require quantitative elements of road condition such as amount of accumulated snow. This paper introduces a method to measure amount of accumulated snow on the road by moving vehicles. The proposed method measures the distance between the placed height of an onboard laser distance sensor on a vehicle and road surface. While the sensor vehicle is travelling, the system obtains distance of cross section of roads in non-snow accumulated season in order to build criteria distance data. In the snowy season, sensor vehicle also measures the distance, the difference between current distance data and the criteria will be amount of accumulated snow.
