To describe the methods that have been used to estimate the casualty reductions that might be expected to arise from a number of potential road safety intervention options raised for consideration as part of the work by the Department for Transport in preparation of a road safety strategy post 2010.


The options are presented in four groups defined by the level of detail of the estimation: options taken to full cost benefit analysis; options taken to partial cost benefit analysis; options with quantitative casualty benefit estimates and options with qualitative casualty benefit estimates. The report describes in detail the analytical methods used to estimate the costs and benefits associated with the list of potential options.

Key Findings:

  • The positive net present value effect of increasing the motorway speed limit to 80mph, due to a reduction in journey times, is off-set by an increase in casualties.




UK-based research, therefore of high significance.
