A new proactive approach to speed limit setting in Queensland

The Speed Limit Review process in Queensland is conducted according to the Department of Transport and Main Roads’ Manual of Traffic Control Devices, Part 4: Speed Controls. The current process is mainly reactive and uses a complex methodology, comparing the crash rate of the road section to the ‘critical crash rate’. It is also heavily reliant on the experience of practitioners to judge the level of road risk. The new SLR process combines proactive road infrastructure risk assessments with refined crash risk assessments to provide more tangible guidance to practitioners and recommend safer speed limits on high risk road sections.
