Impact of Adaptive Front-lighting Systems (AFS) on road safety: Evidences and open points

Almost four years after the entry into force of Regulation ECE 123 on Adaptive Front-lighting Systems (AFS) for motor vehicles, and once the first cars bearing them start to circulate, a comparison between the original idea of AFS and their potential impact in safety and accident prevention is possible. In this work, we present the basic concepts of this new way to light roads and analyse some unforeseen consequences that might arise within the ECE regulatory framework once the presence of AFS becomes massive. This paper also pretends to be an useful guide for some countries like China, still considering the best way to definitively regulate these complex systems whose impact on road safety is expected to be huge.

► Rigorous reflections on AFS influence on road safety and their consequences are really necessary.
► The research on this field has been mainly focused in the bending lights, but not in the new classes.
► A relationship between what these systems are and how they should improve road safety is established.
