Transport for London (TfL) has developed new camera technology that can automatically detect a build-up of vehicles and alert traffic operators to implement congestion-busting solutions. Working with a London-based developer of video analytics systems, TfL has developed image recognition technology to work alongside traffic monitoring CCTV cameras placed at known traffic hotspots to help keep traffic on London's roads flowing smoothly. TheImage Recognition and Incident Detection (IRID) system makes use of videoanalytics technology to analyse a video stream taken from TfL's existing CCTV traffic monitoring cameras and using pre-configured congestion definitions, it warns operators at TfL's London Traffic Control Centre (LTCC) about any build-up of vehicles or incidents, allowing them to take appropriate action very quickly. This technology adds another layer of intelligence, and the up-to-the-minute traffic information can be used to inform the media and other interested parties. The system removes background, irrelevant images, leaving only significant images which can then be analysed appropriately. It works quietly in the background until an incident is detected, which frees up traffic controllers from having to constantly monitor event-free footage. It is effective in all weathers, and benefits all road users in London.
