Steering Behavior during Overtaking on Freeways

The steering behavior of lane change during overtaking on the freeway is experimentally investigated based on a six DOF moving-based driving simulator. 12 experienced participants are involved and instructed to overtake leading vehicles in specially designed scenarios, and their first lane changing of the overtaking is analyzed. The influence of type and speed of leading vehicle on steering behavior are explored by parametric tests. Results show that type of leading vehicle has no impact on steering behavior, including steering wheel amplitudes and duration of each phase. Speed of leading vehicle has significant influence on the first steering wheel amplitude, the second steering wheel amplitude and duration of first phase. This finding may help construct the lane change steering model on freeways with leading vehicle taken into consideration, and promote the freeway driving safety.
