Without radar? Perhaps spot number plates and measure their change in size over time. Or get a community of like-minded folks, all with home-brew ANPR on NTP-synced machines, and known lat/lons, then analyse afterwards to give average speed. For a rat-run you may only need one at each end to come up with data for the council. Cheers, Ralph. -- Next meeting: Bournemouth?
