摘　　要：在驾驶模拟器内植入高速公路超车静态和动态场景,招募30位驾驶人完成超车过程的驾驶模拟试验,并采集驾驶人扫视频率、时间、角度和角速度等参数。将驾驶人视觉区域划分为5个部分,统计计算各区域之间的扫视概率。研究结果表明:超车过程中,目标车辆的速度不影响驾驶人的扫视频率,但对扫视时间、扫视角度和扫视角速度产生正相关影响;与目标车辆为小型车相比,同一速度水平下,超越大型车时驾驶人的扫视时间较长、扫视角度较大、扫视频率较低、扫视角速度较小;驾驶人在原车道和超车道之间的视觉转移概率最高,原车道和超车道是超车过程中驾驶人最为关注的区域。Dynamic and static scenarios of overtaking on freeway were embedded into a driving simulator.Thirty drivers completed driving simulation and their saccade frequency,duration,angle and angular velocity were obtained.The driver＇s visual area was divided into five regions and the probability of viewpoint transition between any two regions was calculated.The results indicate that destination vehicle speed does not influence the saccade frequency,but shows positive correlation with saccade duration,saccade angle and saccade angular velocity.While the destination vehicle speed is the same,when overtaking a truck the driver＇s saccade duration is longer,saccade angle is bigger,saccade frequency and angular velocity are lower than that overtaking a small car.The driver＇s viewpoint transition frequency between initial lane and destination lane is the highest and the driver pays the most attention to these two lanes.
