摘要: 为评估色弱人群正确视认信号灯的影响因素,针对红色弱、绿色弱以及红绿色弱3种不同色弱类型的被试,开展红黄绿3色信号灯色觉静态视认性试验,确定光照强度、视认距离与视认错误率的关系,提出将错误视认结果中的危险导向占比作为信号灯误判严重程度的评价标准。结果表明:光照强度与视认距离对色弱人群视认的影响显著,通常中午12时信号灯视认错误率达到峰值,且上午的视认错误率高于下午;随视认距离的增加,视认错误率不断增加,红绿色弱90 m视认距离的视认错误率高达60%;绿色弱被试的视认最好,但其结果的危险导向占比最高,不容忽视潜在危险。色弱群体视认结果受环境光照强度、视认距离的影响显著,因此,应重视色弱群体驾驶机动车的安全问题。

Abstract: In order to assess influencing factors on people with color weakness to correctly recognize signal lights, static recognition tests of red, yellow and green semaphore color vision were conducted on patients with weakness on these three colors. Relationship between light intensity, visual recognition distance and recognition error rate was established. Then, proportion of hazard orientation in false recognition results was proposed as an evaluation criterion for severity of signal lamp misjudgment. The results show that illumination intensity and visual distance have a significant impact on visual recognition of color-impaired people whose recognition error rate reaches its maximum at 12 noon and is always higher in the morning than afternoon. And the rate increases continuously along with increase of visual recognition distance and that for people with red and green color weakness at 90-meter distance can reach as high as 60%. Visual results of green weak patients is the best but has highest proportion of hazard orientation with potential risks that can not be ignored. Visual correctness of color-weak group is very sensitive to influence of illumination intensity and visual distance, so attention should be paid to safety of color-weak group driving motor vehicles.

Key words: color weakness, static visual identification, illumination intensity, visual recognition distance, error rate of visual recognition
