New digital cameras will be installed around London to better monitor speeding than outdated wet film technology.
The new cameras enable controlling speed compliance along longer road stretches than the wet film cameras, which only provide information about the speed at the exact location of the device.
Transport for London (TfL) has already launched trials of the digital technology along a stretch of A13 east of London and said four more locations will be equipped with the technology as part of the test.
"Ensuring that all road users are acting responsibly is vitally important to ensure that the capital's roads are kept safe for all,” said TfL's strategy and planning director Ben Plowden.
"We are committed to delivering a 40 per cent reduction in the number of people killed or seriously injured on the capital's roads by 2020."
AA president Edmund King said: "Modern, well-signed cameras targeted at accident hotspots are an important road safety tool aimed at helping make roads safer."
Several hundred wet film cameras will be replaced as part of an extensive upgrade of the speed camera network to be completed by October 2016.
The devices will also be installed at traffic lights at busy junctions where motorists can be caught jumping the lights.
