Description of Paper:

We introduce an approach for real-time estimate of individual drivers’ steering avoidance timing while the subject vehicle is approaching the lead vehicle. We model the timing when a driver starts steering avoidance maneuver based on the hypothesis that a driver judges when to steer based on his/her longitudinal collision risk perception. The validity of the proposed model was tested with actual vehicles under various combinations of relative velocities and accelerations. Based on the model, we clarified the relation between the timings of steering and braking avoidance maneuvers of individual drivers.
