Dynamic signs like driver feedback signs use LED lights to reflect drivers’ speeds back at them. These lights are easily seen in the daytime, and are clearly identifiable at night, although nighttime driving can frequently make road signs harder to see. Lit signs draw the eye right away in a fashion that a static sign frequently does not.
New suggestions for the retroreflectivity have been drawn up that make highway signs much simpler to see in dim and dark conditions. Reflectivity is the property that permits something to reflect a light back in the direction of the illumination source in order that it can easily be seen at night. Street signs have this property, and painted lines and markings on roads should, as well.
An indicator without this reflectiveness could be seen at night when the lights hit it right, but that is not guaranteed. Even something illuminated with a brilliant light at night can still be difficult to see well. It’s the retroreflectivity that makes the sign appear to glow, even when the light isn’t shone straight at it. That’s why we’re in a position to see signs at a distance that are on the side of the road, instead of straight in front of us.
New rules recently instituted for traffic signs asked agencies to think up a plan by January early this year for ensuring all signs were in compliance. Even highly reflective signs can become less so over the passage of time, making them harder to see at night.
Guaranteeing that all local signage are covered with the right sort of reflective sheeting, and making certain that these signs are checked to be sure they still reflect correctly over the course of time are part of the new guidelines. Even signs with lights should have this top quality reflective sheeting in place, and agencies should confirm it’s maintained to make it simpler for everyone to see safely at night.
The traffic calming signs from TraffiCalm have always been manufactured to a top quality that meets or exceeds the reflectivity requirements for speed display signs. Check out trafficalmsystems.com today for more information.
