In snowy and cold regions, piled snow on road shoulders may cause traffic congestion and even traffic accidents, and can be a serious problem in maintaining the functionality of urban transportation. In order to maintain the effective width of roads during the winter, piled snow on the road shoulders is removed and cleared, but getting road information requires great deal of time and manpower. In this paper, we propose a method for classifying the effective road width, which is narrowed by piled snow on road shoulders, based on videos captured from an in-vehicle cameras using features focused on piled snow. Estimating road narrowing conditions from in-vehicle cameras will enable ordinary vehicles to collect road information and create an environment that does not require a great deal time or manpower to gather road information.
