Abstract

Rain, even shortfall rain, can adversely influence road safety. Currently, most methods for the detection of slippery road conditions require considerable excitation - by braking or steering - of the tyre forces. Thus, the safety margin between detection and reaction is minimal and dangerous situations can occur, for example hydroplaning. In this study, we explore the detection of wet road conditions by utilising a relatively inexpensive technology, acoustic measurements. A vehicle instrumented with a microphone, GPS and CAN bus data logger was driven at a wide range of speeds and for different road wetness conditions. A wet road surface detector for high and low speeds was developed and evaluated. The detector included a ground-truth database that was constructed by combining speed, road surface condition and audio features. The classification results by testing the performances of different machine learning algorithms on the database are discussed. The best results were obtained with Support Vector Machines.
