老年人路况凸凹识别能力的检测与分析

为探讨老年人视觉功能与老年人交通事故多发现象的关系、预防老年人交通事故的发生,提出了老年人视觉功能的检查与分析方法,并研究了老年人交通事故多发原因。通过对7名老年人及7名年轻人进行道路凸凹识别能力的测试和评估,分析了老年人在3种不同测试条件下年龄增长对视线控制能力及目标物识别能力产生的影响。结果表明,随着年龄的增长,眼球对视线控制能力明显减弱,导致注视点偏下而直接影响到对凸凹物的识别能力,并使老年人在交通环境下对行驶车辆的速度和车距的判断产生偏差,容易导致交通事故的发生。

Analysis of elderly people's discrimination capability on bumpy roads

This study seeks to prevent elderly people's traffic accidents by analyzing the relationship between vision and traffic accidents. A method was developed to analyze people's vision function. The discrimination capability of 7 elderly and 7 young volunteers on bumpy roads was examined. The results indicate that as elderly age, their vision declines which influences their vision control and target discrimination capability. These results suggest that eye control is distinctly reduced with age, which will strongly affect their discrimination capability on bumpy roads. This will cause elderly people to make mistakes in judging speeds of traffic vehicles and distances to traffic vehicles, which will cause traffic accidents.
