Driving maneuver prediction using car sensor and driver physiological signals

Driving maneuver prediction using car sensor and driver physiological signals

Conference

Abstract

​This study presents the preliminary attempt to investigate the usage of driver physiology signals, including electrocardiography (ECG) and respiration wave signals, to predict driving maneuvers. While most studies on driving maneuver prediction uses direct measurements from vehicle or road scene, we believe the mental state changes from the driver when making plans for maneuver can be reflected from the physiological signals. We extract both time and frequency domain features from the physiological signals, and use them as the features to predict the drivers' future maneuver. We formulate the prediction of driver maneuver as a multi-class classification problem by using the features extracted from signal before the driving maneuvers. The multi classes correspond to various types of driving maneuvers including Start, Stop, Lane Switch and Turn. We use the support vector machine (SVM) as the classifier, and compare the performance of using both physiological and car signals (CAN bus) with the baseline classifier that is trained with only car signal. An improved performance is observed when using the physiological features with 0.04 in F-score on average. This improvement is more obvious as the prediction is made earlier.​
