Measuring aggressive driving behavior using signals from drive recorders

In this paper, we propose a method of measuring aggressive driving behavior using driving signals from drive recorders. Drivers are assigned aggressiveness scores for four vehicle operation behaviors, i.e., steering, acceleration, deceleration, and alternation between acceleration and deceleration. A driver´s overall aggressiveness score is then estimated by integrating these behaviors using multiple linear regression. We assess the driving behavior of 78 drivers and compare our assessments to the aggressiveness scores assigned by a risk consulting expert. The proposed method achieves a rank correlation coefficient of 0.74 with the evaluations of the risk consulting expert.
