The Netherlands is test-driving a pavement traffic light system for obsessive smartphone users.
The system, called +Lichtlijn, is designed to aid mobile phone users to cross the road safely.
The system makes use of light-emitting diode (LED) strips embedded into the ground at pedestrian crossings in Bodegraven, close to three schools.
It is hoped the +Lichtlijn will catch the eye of smartphone users who are too distracted to look at the road.
The LED lights will either glow red, orange or green, in combination with the traffic lights at the crossing, to communicate whether it is safe to cross the road.
The system was developed by Dutch firm HIG Traffic Systems.
The company says the increased use of smartphones can be linked to an increase in the number of accidents at pedestrian crossings in recent years.
The system has, however, attracted criticism from the Dutch Traffic Safety Association.
The association believes the system encourages phone users to study their phones while walking, rather than pay attention to their immediate surroundings.
HIG Traffic Systems plans to roll out +Lichtlijn more widely if the trial proves successful.
