道路交叉口司机视觉行为习惯研究

A Study on Drivers' Visual Behavior Habits at Intersections

通过对一些交叉口事故数据的分析表明,交叉口的人车冲突事故,大多数发生在主路右转车辆和右方行人之间。有一种解释是右转的司机只注意左方的机动车辆的潜在威胁,不能及时的看到右方而发生冲撞事故。我们在两个T型交叉口处对司机的视觉特点进行研究,结果验证了假设。这说明司机在经过交叉口时,有一种视觉扫描定式:关注重大的危险而忽略小的危险。文章还根据司机的这种视觉特点提出了相应的对策和措施,结果表明减速措施明显改变了司机的视觉扫描定式,一定程度上有助于司机注意右方行人。

Through an analysis of some crossing accident data, it shows that most accidents at intersections involve vehicles turning right and their right- hand pedestrians. One explanation is that the drivers pay too much attention to the potential threat from their left- hand vehicles and ignore their right side, which was proved by the study in which the drivers＇ visual characteristics were examined at T - shaped junctions. This has proved the drivers＇ visual scanning habits of paying more attention to great dangers than minor ones, and based on this, this article has proposed some measures to change their habits to pay more attention to their right- hand pedestrians.
