Speed perception tests are already used in several countries as part of the driver licensing curriculum; however, this test is not compulsively required in China. The purpose of this study was to investigate the relationship between speed perception and eye movement for different driver groups. Forty-eight drivers, including 28 crash-involved (CI), with rear-end or side collisions, and 20 crash-not-involved (CNI) drivers, were recruited for the speed perception experiments. Drivers' reaction characteristics as well as eye movement data were analyzed. The results showed that CI drivers were more likely to overestimate the speed of visual stimuli and react in advance. The speed perception of CI drivers was more accurate than that of CNI drivers for visual stimuli with middle to high moving speeds, indicating that CNI drivers are more cautious and conservative when driving. Regarding eye movement, significant differences in saccade speed were found between the CI and CNI drivers in the occlusion area under high speed and the occlusion ratio. The relationship between visual pattern and speed perception accuracy was found to some extent. Implications of the speed perception test for the driver aptitude test were discussed.
速度感知测试已在多个国家作为驾驶执照课程的一部分使用；然而，在中国，该测试并非强制性要求。本研究旨在探讨不同驾驶员群体的速度感知与眼动之间的关系。我们招募了 48 名驾驶员，包括 28 名碰撞事故组（CI），涉及追尾或侧面碰撞，以及 20 名未发生碰撞事故组（CNI）驾驶员，进行速度感知实验。分析了驾驶员的反应特征和眼动数据。结果表明，CI 驾驶员更有可能高估视觉刺激的速度并提前反应。对于中高速移动的视觉刺激，CI 驾驶员的速度感知比 CNI 驾驶员更准确，这表明 CNI 驾驶员在驾驶时更加谨慎和保守。关于眼动，在高速和遮挡比下的遮挡区域，CI 和 CNI 驾驶员的眼跳速度存在显著差异。在一定程度上发现了视觉模式与速度感知准确性之间的关系。讨论了速度感知测试对驾驶能力测试的影响。
