基于背景环境和驾驶人年龄的交通标志理解性研究

采用E-Prime2.0软件,对30个常见的交通标志进行了室内模拟实验,测量了不同年龄段的被试人员在有无标志背景环境条件下,对交通标志的理解准确性和视认反应时间.进而,采用卡方检验和t检验方法,检验了不同年龄段的驾驶人员在有、无标志真实背景下对标志的认知准确率和反应时间的差异显著性.最后通过构建年龄、背景和反应时间的回归模型,以揭示标志理解性水平与标志真实背景环境和驾驶人年龄的关系.实验结果表明:青年驾驶人的理解水平和反应时间表现均要优于老年驾驶人,标志的背景环境不会影响标志的理解水平,但是增加了视认标志的反应时间;驾驶人对交通标志的正确理解对于交通安全至关重要.

Research on Comprehensiveness of Traffic Signs Based on Background Environment and Driver's Age

By using the E-Prime2.0 software, 30 common traffic signs were simulated indoors to measure the understanding accuracy and visual recognition reaction time of traffic signs for the recruited subjects of different ages in the environment with or without the background of traffic signs. Then Chi-square test and T-test data analysis were carried out, to test the significant difference of recognition accuracy and response time of signs for the drivers of different ages under the background with or without signs. Finally, by taking the driver age and traffic sign background as independent variables, and the reaction time as the dependent variable, a multiple linear regression model was constructed to reveal the relationship between the sign comprehension level and the real background environment of the sign and driver age. The experimental results show that the driver age and the background environment of traffic signs have a significant impact on the test response time, and the young drivers'' understanding level and response time performance are better than the old drivers; The background environment of signs does not affect the understanding level of signs, but increases the response time of visual recognition signs; Correct understanding of traffic signs is very important for traffic safety.
