Pilot project is being expanded – new technologies are being used
The science city of Darmstadt is expanding its pilot project to protect traffic signs from vandalism. Following initial tests in autumn 2025, further technical solutions will now be tested.
Positive experiences with special coating
In the previous trial, traffic signs were coated with a special anti-sticker coating. According to the city, the results were positive: stickers adhered significantly less or not at all.
Although graffiti can be applied, it can be removed with suitable means without damaging the reflective surface of the signs.
New test phase with protective film
In the next step, the city is relying on an alternative technology. Traffic signs will be additionally equipped with a special protective film that is intended to offer similar properties to the coating tested so far.
The new signs are to be installed throughout the city within the next six to eight weeks.
Goal: less effort and longer lifespan
Head of Transport Paul Georg Wandrey considers the initial results promising. The extended testing phase will allow for the evaluation of further solutions in order to develop a long-term, cost-effective strategy for dealing with vandalism.
The testing phase is planned to last until late summer, with an evaluation scheduled for the third quarter of 2026.
Thousands of signs in the city affected
Darmstadt has approximately 30,000 traffic signs and about 2,000 directional signs. Damage from stickers and graffiti is a recurring problem.
The online reporting system receives several reports daily of dirty or damaged signs. Cleaning and replacing these signs is a considerable undertaking.
Should the technology prove successful, the city plans to equip all new traffic signs with appropriate protection systems as standard in the future.
