Driving is directly controlled by the driver's movement. This study tried to compare differences in gender and headway distances between the DRIVING phase and the SUDDEN STOP phase by using subjects' movement during driving in the simulator. To quantify subjects' movement, the jerk cost function (JC) was used, and conventional vehicle control parameters such as the coefficient of variation of the mediolateral trajectory (MLCV) for lane keeping and the brake time (BT) were also used. As the headway distance increased, MLCV and JC decreased significantly in the DRIVING phase. In the SUDDEN STOP phase, BT was increased and, MLCV and JC were decreased. Differences between genders were detected for both MLCV (males < females) and JC (males > females). The results of this study demonstrate that JC may be used as a variable in evaluating driving performance as influenced by driving conditions and gender.
驾驶直接由驾驶员的动作控制。本研究试图通过使用受试者在模拟器中驾驶时的动作，比较驾驶阶段和突然停车阶段之间的性别差异和车头间距差异。为了量化受试者的动作，使用了急动成本函数（JC），还使用了传统的车辆控制参数，如用于车道保持的横向轨迹变异系数（MLCV）和制动时间（BT）。随着车头间距增加，驾驶阶段的MLCV和JC显著降低。在突然停车阶段，BT增加，MLCV和JC降低。在MLCV（男性<女性）和JC（男性>女性）方面均检测到性别差异。本研究结果表明，JC可作为评估受驾驶条件和性别影响的驾驶性能的一个变量。
