To describe the development of camera programmes in Victoria (Australia) and the UK in order to discuss the types of controversies that have arisen and how they could benefit the use of safety cameras in the US.


Reviews of international practice were undertaken via a literature search.

Key Findings:

  • Speeding increases the likelihood of RTIs and the severity of RTIs that do occur.

  • Speed limits, intended to control top speeds, often are ignored and vehicle speed capabilities far exceed posted speed limits, and thus enforcement is important.

  • Studies in North America, Australia and Europe have found sped cameras to be effective in reducing speeds and RTIs.

  • Public opinion surveys around the world have indicated that speed cameras are supported by the majority of drivers, but are not as popular as cameras that detect and photograph vehicles in breach of a red light.

  • Research from New Zealand suggests that the use of covert cameras can result in greater reductions in casualty RTIs than overt cameras.

  • Despite widely different styles in camera use, studies in Australia and the UK indicate that vehicle speeds and casualty RTI frequencies have been reduced. These reductions have occurred both at camera sites and across the road network.


Speed camera effectiveness


Provides some interesting international findings to give a broader picture of effectiveness.
