我近几年数次到欧洲考查公路施工新技术,诸如:SMA、改性沥青稀浆封层等。在其大地上乘车的途中,对其交通工程设施留下深刻印象！对比国内现状,颇多感慨,本人对此虽无特别研究,却仍如鲠在喉,不吐不快！ 一、护栏上的反光标志全是白色。欧洲对防撞护栏上的反光标志所用颜色有严格规定,除了匝道入口可以使用一个黄色标志和一盏黄色路灯,以提醒司机此处可能有车驶入,要注意观查外,全部使用白色标志,绝对不许使用红色或黄色标志。而我国规范却只规定允许使用白、红、黄三种颜色,并无说明允许使用范围,实际结果是导致了许多起夜间行驶
In recent years, I went to Europe several times to test new technology in highway construction, such as: SMA, modified asphalt slurry seal and so on. On the way of riding on the land, impressed on the traffic engineering facilities! Contrast the status quo in the Mainland, a lot of emotion, although I have no special study on this, but still like a throat in the throat, do not vomit! A, fence reflective signs are all white. Europe has strict rules on the color used for reflective signs on crash barriers, except that a yellow sign and a yellow road lamp can be used at the ramp entrance to remind drivers that there may be a car entering here. , Absolutely not allowed to use red or yellow logo. However, our national standard only stipulates that the use of white, red and yellow colors is allowed. There is no indication of the permitted scope of use, and the actual result has resulted in many night-time driving
