The technology – said to be the first of its kind in the world – will go on trial from summer 2014 on crossings outside Balham and Tooting Bec Underground stations. The system can also adjust traffic signal timings automatically, giving people longer to cross the road if needed.

The news comes alongside the publication of ‘Safe London Streets – Our Six Road Safety Commitments’, a new document which makes clear how TfL, the boroughs and its partners will meet London’s target of reducing the number of people killed and seriously injured on London’s streets by 40% by 2020.

Mayor of London, Boris Johnson said: “I am delighted that London is the first city in the world to be trialling this cutting-edge equipment, which will benefit pedestrians across the city. This really is a fantastic example of how London is leading the way by using 21st century technology to help make it easier for people to get around our great city. Innovation like this is key to keeping London moving efficiently and making our roads safer for everyone to use.’
