Against the backdrop of the energy crisis and the resulting energy shortages, an increasing number of municipalities are considering turning off street lighting. With the development of a long-glowing road marking, road safety and accident prevention at night can be significantly improved.

Long-glowing road marking
Enhancement of traffic safety in the dark
Against the backdrop of the energy crisis and the resulting energy shortages, an increasing number of municipalities are considering turning off street lighting. To maintain traffic safety during darkness, there is now the possibility of equipping traffic surfaces with a long-glowing road marking system (Type I according to ZTV M 13 and DIN EN 1436). Improved visibility in the dark has been demonstrated throughout the entire night. During development, special attention was paid to achieving a standard-compliant white color tone in daylight. The newly developed marking material meets this requirement as well as all other normative standards.
Improved nighttime visibility through newly developed marking material
The improved nighttime visibility is based on the material’s ability to collect and store energy during light phases. This energy is then released as visible light during the darkness. Even on completely overcast days with a cloud-covered sky, the collected energy is sufficient to fully develop its effect during twilight and nighttime hours.
Functional samples of road markings
The long-glowing road marking samples have been subjected to a continuous functionality test at the IAB for years, enduring wind, weather, as well as light and heavy transport and forklift traffic. Since the marking was applied in 2019, no damage to the material has been observed. Additionally, the glowing effect remained constant throughout the long-term test. Comparative measurements of reference materials further confirmed their high effectiveness.
Measurements on sample surfaces
On a temporarily constructed bike path, improved nighttime visibility of 100% was measured under dry and clear conditions. Under wet conditions, an improvement in nighttime visibility of 60% was achieved. These advantages are also likely to positively influence the sensors of semi-automated and autonomous vehicles. Both surfaces experienced residual ambient light during the specified measurement period. In complete darkness, the measurement values and visibility improve significantly.
