【摘要】：为研究车速和环境照度变化对目标物识认时间的影响,选取27名驾驶人,在实际道路和真实照度环境中,以不同车速驾驶车辆对黑白目标物进行识认试验。应用配对t检验法对数据进行差异性显著检验,并分析黑白颜色目标物受车速和照度共同影响时的识认时间规律。结果表明:除照度为500 lx以上且速度为30,40和80 km/h外,驾驶人对黑白目标物的识认有显著性差异;黑色目标物整体的识认时间比白色目标物长,黑色识认性在低照度环境中相对较差;黑色目标物受照度影响主要的波峰为200和400 lx时,白色目标物受照度影响较大的波峰为200和500 lx时;环境照度为101~200 lx,行车速度为40 km/h时,驾驶人基础视力中识认能力下降最快。
[Abstract]:In order to study the effect of vehicle speed and environmental illumination on target recognition time, 27 drivers were selected to carry out recognition experiments on black and white objects by driving vehicles at different speeds in actual road and real illumination environment. The paper applies the paired t test method to test the difference of the data, and analyzes the recognition time law when the black-and-white color object is affected by both the speed and the illuminance. The results showed that the recognition time of black and white object was longer than that of white object, except that the illuminance was more than 500 lx and the speed was 30 ~ 40 and 80 km/h, and the recognition time of black object was longer than that of white object, and the recognition time of black object was longer than that of white object. Black recognition is relatively poor in low illuminance environment, when the main wave peak of black object affected by illumination is 200 and 400 lx, the peak of white object affected by illumination is 200 and 500 lx, and the ambient illumination is 101 ~ 200 lx, driving speed of 40 km/h. The basic vision of the driver has the fastest decline in recognition.
