Speed cameras in an urban setting: a costebenefit analysis
Background To perform a costebenefit analysis of the installation of speed cameras on the beltways of Barcelona. Methods The analysis was performed from the society perspective over a 2-year period using a controlled before-and-after study design. The net benefit was calculated using, as benefits, the willingness to pay for the estimated number of people who avoided injury as a consequence of the intervention, subtracting costs and savings. Sensitivity analyses were performed using the maximum and minimum estimated number of people who avoided injury, assuming that there was a minimum of one death avoided, using the maximum value of a statistical life, assigning all implementation costs to the first year and assuming there was no time lost due to speed reduction. Results Base case results showed a net benefit of €6.8 million. Sensitivity analyses suggested that net benefits could range from €5.6 to €23.1 million over 2 years. Conclusions The use of speed cameras in urban areas has a favourable economic impact even when assessed using conservative assumptions.
