This report was commissioned by the Thames Valley Safer Roads Partnership in 2004 with data supplied by them to the University of Reading for analysis.
The report asks key questions about the impacts of various measures on vehicle speeds including fixed cameras, mobile cameras, and roadside feedback (SIDs). Results include an assessment of both spatial and temporal effectiveness and suggest that short-term measures do not have long-lasting impacts on vehicle speeds.
The evidence also shows that for spot speed cameras (both mobile and fixed) there is only a limited impact in terms of speed reduction once vehicles have passed 300m beyond the location.
The report also includes results of public surveys to determine the level of understanding of specific technologies and their attitudes towards speed enforcement.
