A speed camera program was introduced in Queensland from 1 May 1997 utilising overt deployment of cameras in white commercial vans marked as a speed camera unit at sites chosen on the basis of crash history. Sites at which cameras operate on a particular day are chosen using randomised scheduling and have grown in number from 500 at program commencement to over 2,500 by June 2001. This study has investigated the crash effects of the speed camera program in Queens1and over the period from its introduction in May 1997 to the end of June 2001 in areas within 6 kilometres of speed camera sites that had been used up to the end of the study period. When operating at maximum coverage, the Queensland speed camera program was estimated to have produced a reduction in fatal crashes of around 45 per cent in areas within 2km of speed camera sites. The benefit cost ratio estimated for the program over the period from its introduction to June 2001 was 47. (Author/Publisher)
