This luminous floor marking, unique in France, helps to enhance the safety of cyclists.
First in France, a luminous bike path thanks to a painting that stores sunlight and restores it at night, was inaugurated last Monday in Pessac. This route connects the university campus to Avenue de Saige.
This photoluminescent road, which aims to enhance road safety, consists of a bright green floor marking, thanks to a road paint developed by OliKrom. The company from Gironde produces itself its magic inks and paintings. They change color depending on light, temperature and pressure. Smart pigments “guarantee a luminous intensity that lasts all night“, asserts Jean-François Létard, the boss of the start-up. It was the winner, along with Eiffage, of the Roads for the Future call for projects, launched by Ademe in 2017.
A failure in the Netherlands
“A first experience of luminescent painting was tried a few years ago in the Netherlands but it was a failure very quickly, our road marking is durable, it is resistant to UV, heavy goods traffic and humidity” says François Olard, research and innovation director of the Eiffage group, which has partnered with OliKrom to develop this patented technology.
Ultimately, this photoluminescent paint will enhance road safety by improving the visibility of horizontal and vertical road markings (emergency stop lanes, crosswalks, bike paths …) at night as well as with deteriorating weather conditions.
“The marking will improve the visibility at night from about 50 to 100 meters, it will trace the road off, beyond the headlights, and allow the user to anticipate his actions,” said François Olard.
The public works group Eiffage is preparing to commercialize this painting.
