这项工作调查了在真实道路和模拟器条件下，在弯曲和直线路段行驶时横向位移的差异。我们观察了100名持牌司机在农村道路上和100名在固定基地模拟器上。使用摄像机测量真实道路上的速度和横向位置。分析表明，车辆在真实道路上的平均侧向位移总体上要高于模拟路面。然而，在高速度的弯曲路段和低速度的直线路段，这些差异减小。还发现，无论在弯曲路段还是直线路段，车辆横向位移在真实道路上的标准差都明显低于模拟器中的相应值。本研究的实际或潜在应用与基于模拟实验结果得出的更真实的驾驶行为情景评估有关。
This work investigates differences in lateral displacement when driving on curved and straight road sections in real-road and simulator conditions. We observed 100 licensed drivers on a rural road and 100 in a fixed-base simulator. Speed and lateral position on the real road were measured using videocameras. The analysis indicates that the mean vehicle lateral displacement is in general higher on the real road than in the simulator. However, these differences decrease for higher speeds at curved sections and for lower speeds at straight sections. It was also found that the standard deviation of the vehicle lateral displacement is significantly lower on the real road than the corresponding values in the simulator, at either curved or straight sections. Actual or potential applications of this research are related to a more realistic assessment of driving behavior scenarios derived on the basis of simulation experiment results.
