Objectives

In order to reduce speed related crashes, Australian police services commissioned an increase in the use of speed and red light cameras. The study aimed to measure the changes in driver speed behaviour across the road network over time.

Methodology

The study used ten annual speed surveys, conducted in rural areas between 2000 and 2013. The year 2000 was used as a baseline In the nine surveys conducted between 2003-2013 attempts were made to survey all sites chosen from the random sample of 95 sites chosen for the baseline surveys. Seven day speed data was collected at each site. Each survey resulted in over 1 million vehicles travelling in a free flowing traffic environment.

Key Findings:

  • At baseline the levels of compliance with the speed limits was 60.6%.

  • By 2013 this had reached 70.8%. In addition, the number of drivers travelling at more than 10km/h above the speed limit decreased from 8.6% in 2000 to 5% in 2013.

  • The number of speeding drivers in 2013 was 42% less than in 2000.
