Hi-tech crossing alerts drivers to pedestrians on mobiles

A hi-tech crossing alerts drivers when a pedestrian using a mobile phone steps in front of traffic.

The surface of the so-called smart crossing features LED lights which illuminate based on the movement of road users detected by cameras.

This means a thick red line lights up across the road when someone walks out unexpectedly.

Other features include the crossing becoming wider when there are lots of people waiting to use it, and extra warnings to cyclists when pedestrians are hidden by high-sided vehicles.
