New safety camera on trial in London A new type of safety camera that does not flash and requires no film is being tested in west London. The digital speed camera or "d-cam" photographs drivers faces and number plates and, if it wins Home Office approval, could be used nationwide. Transport for London has tested it on London's A4 Great West Road since April. It detected speeding drivers but no fines are being issued in the trial. Developed by west London firm Truvelo, the new digital speed and red light camera does not flash to alert drivers when it photographs speeding vehicles. A Transport for London spokesman said the number of people killed or seriously injured on London's roads has been reduced by 41% since the mid to late-1990s. "Safety cameras have played an important role, along with other road safety measures such as 20mph zones, advertising and educational initiatives," he added. I'm guessing the other road safety measures contributed slightly more. When on earth does anyone have the opportunity to speed on Londons roads even if they wanted to?
