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。
In order to help drivers win more operating time and improve traffic safety , the legibility of traffic signs was researched. LED active luminous guide signs designed to be trialed on the middle ring road of Taiyuan city and reflective film signs of the same specification were taken as research objects. Legibility researches were made both on LED active luminous traffic signs and reflective film signs under different ex- periment conditions of the day and night. The results show that the legibility of traffic signs which recognized by drivers is related to their environment and condition, and that there is a little difference between the legibility of LED active luminous traffic signs in day and that at night , but it is much better than the legibility of reflective film signs at night, the former is greater than the latter by 1.3-1.9 times.
