15名参与者使用一个固定底座的驾驶模拟器，积极驾驶他们的车辆穿过一条乡村道路，驶向一个十字路口。他们的任务是安全地穿过十字路口，穿过来往车辆的间隙。时空任务的限制，操纵不同的初始条件（偏移）相对于交通间隙在交叉口的到达时间。纵向操纵的铅和尾随车辆形成的交通间隙的运动特性允许评估的影响，全球（间隙相关）和本地（铅/尾随车辆相关）方面的车辆间的间隔。结果表明，不同的初始偏移引起的功能，连续和渐进的调整，在接近速度，早在接近交叉口。在接近的最后阶段，驾驶员有系统地加速，平均来说，在交通间隙的中心稍微前面穿过差距。一个特殊目的的方差分析表明（全球）差距的影响，如差距的大小和速度的特点。进一步的分析表明，前车的运动特性比后车的运动特性对接近行为的影响更大。结果表明，在拦截交通间隙中心和避免与前车、尾随车碰撞的基础上，实现了接近速度的在线调节。(C)2012爱思唯尔有限公司版权所有。
Using a fixed-base driving simulator, 15 participants actively drove their vehicle across a rural road toward an intersection. Their task was to safely cross the intersection, passing through a gap in the train of incoming traffic. Spatiotemporal task constraints were manipulated by varying the initial conditions (offsets) with respect to the time of arrival of the traffic gap at the intersection. Orthogonally manipulating the motion characteristics of the lead and trail vehicles forming the traffic gap allowed evaluating the influences of the global (gap-related) and local (lead/trail-vehicle-related) aspects of the inter-vehicular interval. The results revealed that the different initial offsets gave rise to functional, continuous and gradual adjustments in approach speed, initiated early on during approach to the intersection. Drivers systematically accelerated during the final stages of approach, on average crossing the gap slightly ahead of the center of the traffic gap. A special-purpose ANOVA demonstrated an influence of (global) gap characteristics such as gap size and speed. Further analyses demonstrated that the motion characteristics of the lead vehicle exerted a stronger influence on approach behavior than the motion characteristics of the trail vehicle. The results are interpreted as signing the online regulation of approach speed, concurrently based on intercepting the (center of the) traffic gap and avoiding collision with the lead and trail vehicles.
