【摘要】：雾通过本身的光学现象影响驾驶员视觉和心理,从而导致事故的发生。雾对驾驶员视觉的影响主要表现在雾对驾驶员车距估计及目标识别距离影响两方面。通过分析雾对驾驶员视觉影响机理,提出雾滴粒子对光的衰减以及对相对亮度的影响。以现场试验方式对雾天与驾驶员车距估计及对驾驶员目标识别距离关系进行分析,实验结果表明,雾环境下驾驶员对车距的估计会偏大,且能见度越低驾驶员对车距估计偏差越大;随能见度降低驾驶员对目标识别距离降低,且能见度低于150m时,目标识别距离降低速率急剧增大。
[Abstract]:Fog affects the driver's vision and psychology through its own optical phenomena, which leads to accidents. The influence of fog on driver's vision is mainly reflected in the influence of fog on distance estimation and target recognition distance. Based on the analysis of the influence mechanism of fog on the driver's vision, the influence of droplet particles on light attenuation and relative brightness is put forward. The relationship between the distance between fog and driver and the distance between the driver and the driver is analyzed by field test. The experimental results show that the estimation of the distance between the driver and the driver is on the high side under the fog environment. And the lower the visibility, the greater the deviation of the driver's estimation of the vehicle distance; With the reduction of visibility, the recognition distance of the driver to the target decreases, and when the visibility is less than 150 m, the reduction rate of the target recognition distance increases sharply.
