Towards a new dedicated approach
A working group including the Foundation for Civil Engineering Development, the Universities of Gdańsk and Warsaw, and the Research Institute of Roads and Bridges came recently came up with guidelines for pedestrian crossing
positive contrast for pedestrian silhouettes observed from the driver’s perspective. This approach considers the luminance requirements of the road lighting class and the light reflected on pedestrians. These guidelines are not yet translated into regulations and standards, but might be soon, as normalisation bodies are currently busy revising their recommendations.

They propose introducing new lighting classes (PC) for dedicated pedestrian crossing lighting solutions. Their purpose is to create a highly
