Smart LEDs light the way to road safety

Light-emitting diodes (LEDs) powered by the sun could soon be guiding drivers. Together with sensors and wireless communication developed by an EU initiative, they will also help control centres to manage traffic patterns on a larger scale for enhanced safety.

Almost every driver at some point has come across the lines of small, reflective spheres marking lanes or shoulders when lit up by vehicle headlights. These road studs, also known as cat's eyes, have entered a new era. Incorporation of LEDs increases visibility as compared with reflection, provides lighting at angles not illuminated by headlights and enables use of colours to indicate different conditions.
