Title:

Final Report on Signal and Image Processing for Road Condition Classification

Abstract:

This paper evaluates two systems for classifying road conditions by using cameras and microphones respectively. One determines the road condition from an image of the road. Another uses a similar method to classify the road condition by analyzing the characteristic sound signals from passing cars on different road conditions. The systems have been operational during the winter season 2000/2001 in addition to manual observations of the road. The results from the evaluation are very satisfying especially for icy and wet road conditions.
