Or even simpler low cost radar devices that sense a vehicle stopped in a live lane, they have one rather major advantage over CCTV in that they work even in zero visibilty due to fog or spray. Such small radar transponders are cheap enough and use so little power that they are being fitted to mass market cars. Front facing systems are used in adaptive cruise control and collision avoidance systems while rear facing radars are used by blind spot warning systems.jusme wrote: ↑Sun Dec 27, 2020 20:17On the subject of SVD, that seems to me like an ideal application for that over-hyped pattern recognition technology, laughingly called "AI". It could be used to watch all CCTV images simultaneously and in real-time, and track the progress of every vehicle. If any unusual pattern developed a human operator could be alerted to review the incident and take action as appropriate. With this "AI" assistance a small number of operators could cover the entire network 24x7.
Of course it would require > 100% CCTV coverage (which should be a requirement anyway, IMO), and good enough CCTV images, so maybe we'd need to put in (or put back) lighting. That might also help drivers see what's happening better, given that "drive at a speed such that you can stop in the distance you can see" is never going to be a reality, especially on a motorway at night.
This is a typical module
