Evaluation Index of Lane Change Behavior for Driver Support to Improve Unsafe Behavior

Using a driving simulator, we conducted an experiment in which skilled drivers comprehensively evaluated a danger/disturbance level of various lane change behaviors from the view point of the following vehicle driving in the passing lane. Using multiple regression an alysis, we specified danger/disturbance factors, quantitatively identified the condition of each factor occurrence, and found some physical quantities that strongly in fluence the danger/disturbance level. Finally, we obtained an overall index for evaluating danger/disturbance level of lane change behavior
