Ceinwen,It is a fair question to ask.I did look around for other council area wide traffic management schemes using APNR and I couldn't find anything as large as the S Chiswick proposal, let alone anything larger.ANPR has been used for bus gates and emergency services access, so a limited type of vehicles. It has also been used for school streets schemes, which typically cover a limited area around a school.The only other example I could find of a council using ANPR for an area wide scheme was around the East Ham area of London Borough of Newham. This went inservice towards the end of last year. The area doesn't appear to be as large as proposed for Grove Park.If anyone can find other council schemes using ANPR for managing traffic over a wide area, then please post!The Hounslow scheme as proposed may very well be the largest one run by a council in London so far, maybe the UK.If you think about it, they need to store car registrations (which they have for cars in a CPZ zone but not for off-street parking) Check captured registrations against the list, issue charges for non-registered number plates, have a process for residents to update car registrations, have a process for residents to complain if they believe the charge isn't valid etc. etc. I suspect none of the systems involved with this talk to each other so a lot of manual workarounds. It's a lot of work.From a project management point of view, I could understand why they want to limit the numbers, understand the issues, walk before running etc.Low traffic neighbourhoods are common in the Netherlands, Belgium and other countries. They don't use ANPR. They would just stick in planters or bollards and if that means residents driving have a detour of 1km, 2km, or more, then so be it. The priority is walking and cycling, not making it easy to drive.
