article imageGlow in the dark road project continues

Glow in the dark road markings pilot in the Netherlands is in progress. The initial findings found the markings were sensitive to large amounts of moisture, rendering them "too dark." However, engineers will continue testing and produce a new version.
The project, dubbed Smart Highway, is designed as an alternative to street lighting (and with it, cheaper because lamps would not need to be switched on at night). The pilot project was announced month on the N329 in Oss, approximately 100km south east of Amsterdam, according to the Daily Mirror.
The paint used for the markings contained a "photo-luminising" powder. This additive charges up in the daytime and slowly releases a green glow at night. Once charged, the lines can glow for around eight hours. The idea was put together by engineering firm Heijmans and artist Daan Roosegaarde.
Roosegaarde told Business Insider at the time of the launch: "I forced them to look at movies of jellyfish. How does a jellyfish give light? It has no solar panel, it has no energy bill. And then we went back to the drawing board and came up with these paints which charge up in the daytime and give light at night."
However, the BBC has reported that the road markings were sensitive to large amounts of moisture due to rainfall. This has led to the road markings were not giving out a consistent level of light. However, the engineering team behind the study have indicated that they will continue with testing and they aim to produce a new version of the 'road paint' ( Glowing Lines 2.0 version).
