Vehicle speeds in South Australia

摘要

The latest report from CASR on vehicle speeds in South Australia notes changes since 2002 and relates them to countermeasures over that time. Low speed roads showed a marked reduction in mean speed following the introduction of the default 50 km/h speed limit in 2003 and for some years after. After a general increase on these roads from 2005 to 2007, speeds were found to decline in 2008 and again in 2010. Speeds on high speed rural roads have remained relatively unchanged between 2006 and 2010 except on 100 km/h roads between 2007 and 2008 where there was a significant drop in speeds. The report conjectures that lower enforcement tolerance and a large advertising campaign may have had an influence.
