LED交通标志的视认性试验研究与分析
发布时间:2018-09-12 09:51
【摘要】:为帮助驾驶员赢得更多反应操作时间从而提高行车安全性,研究分析交通标志的视认性,尤其是夜间视认性。以太原市中环路试设的LED主动发光指路标志及同规格的反光膜标志为研究对象,分别在昼夜条件下对其视认特性开展试验研究。研究表明,驾驶员对标志的视认性与其环境及自身条件有关;LED主动发光交通标志在白天与夜间的视认性相差甚微,但其在夜间的视认距离明显优于反光膜标志,是反光膜标志的1.3~1.9倍。
[Abstract]:In order to help the driver gain more reaction time and improve the traffic safety, traffic sign recognition, especially at night, was studied and analyzed. Taking the LED active luminescence guide mark and the reflective film mark of the same specification as the research objects, the visual recognition characteristics of the LED were studied under the condition of day and night respectively. The results show that the drivers' visual recognition of the signs is related to their environment and their own conditions. There is little difference in the visual recognition of LED traffic signs during the day and at night, but the visual recognition distance at night is obviously better than that of the reflective film signs. It is 1.3C 1.9 times of the mark of reflective film.
