Objectives:

To investigate what happens when it is announced to the public that speed cameras are no longer in operation.

Methodology:

This report looks at the evidence retrieved from four sites (six ‘locations’) in Oxfordshire in the 32 days following the well publicised speed camera switch-off.

Key Findings:

  • The results, although only at a limited number of locations for a short period of time, indicate that motorists do alter their speed choices when they know a fixed speed camera is not loaded.

  • Even the most conservative analysis shows a 2.9 to 4 times increase in offending at sites only one month after the switch-off.

  • If seasonal variations and more recent offence rates are taken into account then the increases are significantly higher.

  • Local authorities around the country should bear these results in mind if they are considering a similar approach to Oxfordshire as the deterrent effect of the housing alone is diminished by public announcements regarding their operational capacity.

Themes:

Speed camera effectiveness

Comments:

A small scale piece of research in terms of time, but already shows a change in behaviour following camera switch off.
