Trials of new technology that would give cyclists more time to get through traffic lights at busy junctions are being tested in London.
The technology detects the numbers of cyclists travelling along a route, and enables traffic signal timimgs to be adjusted to give more green time when there are high numbers of cyclists at key junctions during peak hours.
The trials come as the latest road death statistics fro London revealed that six cyclists have been killed this year - all in collisions involving lorries.
Lucrezia Millarini reports from east London.
Last year 432 people died on London's roads, a drop of 12% from 2013 but still vastly more than in other comparative European cities.
The trials involve two types of technology - one radar-based and one thermal based, which measures the heat of riders as they enter the detection zone - to measure their effectiveness in detecting cyclists.
Transport for London (TfL) will carry out three more trials along the cycle superhighway to test both, with the possibility of introducing them across the capital.
