ABSTRACT

We characterized the control mechanisms underlying crossing an intersection with vehicular traffic. Specifically, we identified potential markers of the coupling between information and movement through a kinematic analysis of the approach. We exposed participants in a driving simulator experiment to several scenarios. We manipulated task constraints by varying the acceleration capabilities of the vehicle and the time available to make speed adjustments. The results highlighted gradual, systematic adjustments, which make it possible to cross the intersection in a zone that is close to the center of the intervehicular gap. The functional nature of these adjustments was highlighted by concomitant and opposite variation in the variability of current speed and current deviation. In all cases, an increase in the standard deviation of speed was accompanied by a reduction in the standard deviation of current deviation. Neither time to make adjustments nor acceleration capabilities modified the observed kinematic patterns, but they did modulate the adjustments that were produced. Overall, these results were consistent with a control mechanism based on the implementation of an information–movement cycle.

摘要

我们表征了与车辆交通交叉路口的控制机制。具体来说，我们通过对该方法进行运动学分析，确定了信息与运动之间耦合的潜在标记。我们向驾驶模拟器实验的参与者介绍了几种情况。我们通过改变车辆的加速能力和可用于调整速度的时间来操纵任务约束。结果强调了逐步的，系统的调整，这使得可以在接近车辆间隙中心的区域内交叉路口。这些调整的功能性质通过电流速度和电流偏差的变化的同时而相反的变化来突出显示。在所有情况下，速度标准偏差的增加伴随着电流偏差标准偏差的减小。既没有进行调整的时间，也没有加速能力来修改观察到的运动学模式，但是它们确实调制了所产生的调整。总体而言，这些结果与基于信息移动周期实施的控制机制相一致。
