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.
这项研究调查了在真实道路和模拟器条件下，在弯道和直道上行驶时横向位移的差异。我们观察了100名在乡村道路上的持照驾驶员和100名在固定基座模拟器中的驾驶员。使用摄像机测量真实道路上的速度和横向位置。分析表明，真实道路上车辆横向位移的平均值总体上高于模拟器中的值。然而，在弯道处较高速度行驶以及直道处较低速度行驶时，这些差异会减小。还发现，无论是弯道还是直道，真实道路上车辆横向位移的标准差都显著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对驾驶行为场景进行更现实的评估有关。
