The Victorian studies also show that the number of fines from a specific speed camera typically goes down over time, presumably because repeat offenders get fines/lose their licences http://www.camerassavelives.vic.gov.au/home/statistics/trends+in+fines+interactive+chart http://www.camerassavelives.vic.gov.au/home/statistics/trend... In many Australian states (including South Australia) the payments from fines goes to a Community Road Safety Fund which is then given mostly (except for funding for holiday double demerit campaigns) to community and motorist groups to run their road safety activities, not the road authorities or police who would advise on where to put the cameras. So hopefully there is no incentive for "revenue raising" cameras - wouldn't the potential and actual crashes in the underpass have caused the camera to be installed?
