Detection of driver's anomaly behavior using wireless 3D-accelerometers

In this paper, we propose a method for directly measuring and analyzing driving behavior using wireless SD-accelerometers. Whereas existing systems installed many sensors into a specially equipped test vehicle, to indirectly measure driving behaviors, our method uses wireless 3D-accelerometers attached to a driver for directly measuring his/her behaviors in a vehicle. After applying independent component analysis (ICA) to reduce car-caused noise, our method detects anomalies in driving behaviors using one-class SVM. By directly measuring driving behavior, our method allows to point out anomalies in driving behaviors characteristics to novice drivers with precision of 71.1% and recall of 73.9%.
