The traffic figures were the result of traffic counters laid on most of the roads in the 20mph zone some months ago. I remember seeing them at the time and wondered why they were doing such an intensive survey - now we know! Lewisham's (one) mobile camera unit was mentioned at the Lewisham Transport Operational meeting this week by Darien Goodwin. I'm fairly sure he said that it hadn't yet been used for real but I wouldn't swear to it.

I presume that the mobile camera unit is like those used by the Police and has to be manned - so there is an additional operational cost compared to a fixed camera[/b]. However, you don't have to raise many ?60 fines per hour to pay the wages of the operators!
