To investigate the effect of visual field defects on driving performance, and to predict practical fitness to drive.
The driving performance of 87 subjects with visual field defects due to ocular abnormalities was assessed on a driving simulator and during an on-road driving test.
The final score on the on-road driving test and simulator indexes, such as driving speed, viewing behavior, lateral position, time-headway, and time to collision.
Subjects with visual field defects showed differential performance on measures of driving speed, steering stability, lateral position, time to collision, and time-headway. Effective compensation consisted of reduced driving speed in cases of central visual field defects and increased scanning in cases of peripheral visual field defects. The sensitivity and specificity of models based on vision, visual attention, and compensatory viewing efficiency were increased when the distance at which the subject started to scan was taken into account.
Subjects with visual field defects demonstrated differential performance on several driving simulator indexes. Driving examiners considered reduced speed and increased scanning to be valid compensation for central and peripheral visual field defects, respectively. Predicting practical fitness to drive was improved by taking driving simulator indexes into account.
研究视野缺损对驾驶性能的影响，并预测实际驾驶适宜性。
在驾驶模拟器上以及实际道路驾驶测试中，对87名因眼部异常导致视野缺损的受试者的驾驶性能进行评估。
实际道路驾驶测试的最终得分以及模拟器指标，如驾驶速度、观察行为、横向位置、车头时距和碰撞时间。
视野缺损的受试者在驾驶速度、转向稳定性、横向位置、碰撞时间和车头时距等指标上表现各异。有效的补偿措施包括：中央视野缺损时降低驾驶速度，周边视野缺损时增加扫视。当考虑受试者开始扫视的距离时，基于视力、视觉注意力和代偿性观察效率的模型的敏感性和特异性会提高。
视野缺损的受试者在多个驾驶模拟器指标上表现各异。驾驶考官认为降低速度和增加扫视分别是对中央和周边视野缺损的有效补偿。考虑驾驶模拟器指标可改善对实际驾驶适宜性的预测。
