The future Directive on Road Infrastructure Safety Management showcases the importance of readability and detectability of road markings and signs both by human drivers and automated driver assistance systems.

The European Union Road Federation (ERF) welcomes this development as signs and markings represent a cost-effective road element that can ensure safe driving conditions while also providing the best guidance. This is especially important under adverse weather and vision conditions.

Two dedicated ERF technical working groups, that gather main representatives of the sector, are constantly exchanging knowledge and investigating how markings and signs can optimise infrastructure performance under new mobility environments.

Since the publication of the 3rd Mobility Package by the European Commission in May 2018, experts from different organisations have worked on the analysis of current solutions to ensure safe driving conditions. As a result, the first set of technical recommendations to facilitate the recognition of road markings by human and vehicle vision is now published calling on the following performance requirements:

  • Road Markings in night visibility should never drop below 150 mcd/lx/m2 night visibility under dry conditions and never below 35 mcd/lx/m² under wet and rainy conditions
  • The width of Markings should never be less than 15 cm
  • Ensure a sufficiently high contrast ratio between marking and pavement (never below 3:1) to mitigate false readings caused by glare
  • Facilitate harmonisation of markings design and layout across various countries

“We are glad to share expertise and successful experiences with the European Commission and Member States on how markings can better perform towards human and vehicle vision. For that, we focus our work on co-funded EU projects and several technical publications, so as to ensure that the results reach as many stakeholders as possible including from other regions as the United States” commented Harald Mosböck, Chair of the Working Group on Road Markings.
