Seems speed cameras are not the only answer. No government revenue though, so there's no chance of this here in Vic. Something for MUARC to study? http://www.dailymail.co.uk/news/article-1364782/Trees--imaginative-alternative-speed-cameras.html Trees instead of speed cameras? Study finds they are just as effective in slowing down traffic Trees could soon be used instead of speed cameras after a Government study found they were just as effective in slowing down traffic. Creating an avenue of trees and hedges had a dramatic impact on motorists’ behaviour, a trial in Norfolk has found. Ministers welcomed the 'imaginative alternative' to speed cameras. The experiment at four villages showed that drivers lowered their speed because of the reduction in their peripheral vision. Overall there was a 20 per cent drop in the number of motorists driving at between 40mph and 60mph and average speeds fell by 1.5 per cent across the villages of Overstrand, Martham, Coltishall and Mundesley.
