Abstract	A systematic and ongoing method of measuring vehicle speeds was introduced in South Australia in 2007 to assess the effects of speed reduction countermeasures and to monitor the speed behaviour of South Australian motorists over time. More than 100 sites around South Australia have speed measurements taken for a one-week period at the same time each survey year. This Report summarises the data collected in 2022 and makes comparisons with previous surveys dating back to 2007. The following general observations are apparent when considering all the surveys and all the speed measurements: vehicle speeds have been trending down on all road types over the course of the surveys; the percentage of vehicles obeying the speed limit has been increasing; reductions in high level speeding are more pronounced than those for low level speeding; speed limit compliance is lowest on Adelaide 50 km/h collector roads and rural 100 km/h arterial roads; and vehicle speeds in 2022 appeared to generally decrease compared to 2020.
