40 km/h local area speed limit trial, Unley - South Australia: final report and recommendations

The Unley 40 km/h local area speed limit trial extended over a total period of 15 months. Its objective was to assess the reductions in traffic speeds following the imposition of the lower limit accompanied by systematic police enforcement using radar speed cameras at low and high levels of intensity. In particular, it was desired to establish whether such enforced lower speed limits could serve as an alternative to the installation of physical speed controls within local area traffic management schemes. The Working Party concluded that speed reductions achieved were lower than would be achieved using physical devices and that low level enforcement is viable. The Working Party recommends that sign-only 40 km/h local area speed limits should not be used as an alternative to physical speed controls, but a reduction in the general built up area speed limit should be the subject of widespread community debate; local area speed limits should be used only in conjunction with physical devices in the meantime and sustained low level enforcement programs should be used in such areas.
