Abstract: The Default Urban Speed Limit (DUSL) in South Australia was reduced from 60 to 50 km/h from March 1, 2003. As a part of an evaluation of the effectiveness of the reduced DUSL, the South Australian Department of Transport and Urban Planning (DTUP) arranged for speeds to be measured at 52 randomly selected sites of the 50 km/h default urban speed limit. The overall reductions were calculated by taking the mean of all speeds measured on roads of the given road type before and after the change in DUSL. It was found that overall mean speeds on roads that changed from 60 to 50 km/h dropped by 2.2 km/h and mean speeds on major roads that retained their 60 km/h limit dropped by 0.7 km/h.
