Что такое светящаяся в темноте дорожная разметка?

Тhe concept of Glow in the dark Road Markings gained heightened attention following an article from BBC News, catching public interest in this innovative safety feature. Glow in the dark road markings come in various forms, primarily сolvent-based paint, water-based paints, and thermoplastic paint. Solvent-based paints are chosen for outdoor road due to their durability and strong adhension. Water-based paints, known for their экологически чистые преимущества, are equally popular in some countries. Thermoplastic paints represent another excellent choice with its weather and ware resistant , allowing for the fusion of glow in the dark pigments with thermoplastic materials.

Ночью видимость ухудшается, и некоторые участки, например крутые повороты и пешеходные переходы, становятся особенно опасными местами аварий. Многие города пытались сделать ночи безопаснее, устанавливая больше уличных фонарей, улучшая дорожную разметку и модернизируя светофоры, но эти улучшения не всегда распространяются на все районы. Там, где недостаточно освещения, несчастные случаи происходят гораздо чаще. более 40% аварий происходит в местах с плохим освещением.

Светящаяся дорожная разметка в первую очередь служит визуальным предупреждением, а не освещает пути, как традиционное освещение. В данной маркировке используются фотолюминесцентные материалы, поглощающие свет в дневное время и emit a pale yellow-green phosphorescence at night. Это мягкое свечение особенно useful in darkness for sidewalks, sharp curves, and other high-accident areas, enhancing safety by providing visual signals.

Charged by natural light during the day, these photoluminescent materials ensure that even in dark areas , they обеспечить значительную выгоду в безопасности с вечера до полуночи. The phosphorescence light is a little weak, but still workable. This makes them an ideal solution for enhancing road safety in different settings, particularly where electrical solutions are impractical.

There are various glow paints available on the market. When selecting one, there are three key indicators to consider, which include color, glow powder brightness level, and powder dosage. For road markings, yellow-green color is the best choice because its unique chemical properties provide the highest brightness and the longest afterglow time, which are closely related to the safety attributes of road markings. Higher brightness powder is suggested since in the evening the outdoor is not extremely dark due to moon light. Higher one can present better glow performance. The dosage of glow powder is also important. Road markings usually require a 20%-40% ratio. Lower dosage will result in lower brightness and shorter afterglow. Conversely, paints with a higher dosage have better glow performance.

You might have seen some pictures on the Internet that the glow in the dark lines seem to light up faces just like regular electric lights. It’s got a lot of folks excited about using that glow in the dark paint on roads. But here’s the thing – in real life it’s not quite like that. The glow in the dark paint actually gives off this yellow-green glow very softly, kind of like phosphorescence. You can see it outdoors from evening till midnight, but it’s pretty subtle. When you snap a pic with your phone or camera, though, the auto exposure makes it look way brighter than it actually is. That can throw off folks who aren’t familiar with how it works.
Our field tests have found that the glow in the dark marker line remains visible until midnight only in complete darkness without any electric light around. It can only provide guidance to pedestrians when there is no influence from headlights, street lights and other light sources. Therefore, glow road marking is more suitable for roads in rural areas, suburbs, or areas without electricity facilities, or in places where public lighting is turned off at night. In such situations, glow road marking will have the greatest impact in rural areas and suburbs, providing a glowing guide for cyclists and walking people.
