AuthorsKloeden CN, Woolley JE, McLean AJ
Year2005
TypeJournal Article
AbstractFrom March 1,2003, the Default Urban Speed Limit (DUSL) in South Australia was reduced from 60 to 50 km/h, unless otherwise signed. As 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 across the State prior to the introduction of the 50 km/h default urban speed limit, and again approximately a year later. The sites consisted of the following: 10 main roads (arterials) which retained the 60 km/ h speed limit; 12 collector roads where the speed limit was changed to 50 km/h ; 18 local roads in the metropolitan area where the speed limit was changed to 50 km/h; 12 local roads in rural townships where the speed limit was changed to 50 km/h.
