摘要

过十字路口是一项复杂的驾驶任务,对老年司机来说尤其困难。这项任务需要多个驾驶子任务的精确协调,对感知、注意力和运动控制提出了很高的要求,这些要求会随着年龄的增长而下降。我们分析了一辆仪表车辆在十字路口的通行行为,发现不同年龄的驾驶员在右转时同步速度和航向控制的方式存在显著差异。年纪较大的司机大多是在静止不动时驾驶方向盘,而不是像年纪较小的司机那样在加速时驾驶。这种从平行控制到串行控制的转变是一种补偿解决方案,驾驶员采用这种解决方案来应对与年龄相关的感知、认知和运动控制能力的下降。交叉口转弯的系列化通过消除在不同驾驶子任务之间切换注意力的需要,在很大程度上减少了注意力需求。

SERIALIZATION OF VEHICLE CONTROL AT INTERSECTIONS IN OLDER DRIVERS.
Negotiating intersections is a complex driving task that is particularly difficult for older drivers. This task requires accurate coordination of multiple driving subtasks, placing high demands on perception, attention and motor control that are known to decline with age. We analyzed intersection negotiation behavior in an instrumented vehicle and found striking differences in how drivers of different ages synchronize speed and heading control when turning right. The older drivers performed most of their steering while standing still instead of while accelerating as younger drivers do. This shift from parallel to serial control is a compensatory solution that drivers employ in response to age related decline in perception, cognition, and motor control abilities. Serialization of turning at an intersection reduces attentional demands largely by eliminating the need to switch attention between different driving sub-tasks.
