In order to use the cost-optimization procedure of dynamic programming to rank safety improvements, improvement costs and benefits must be input. The benefits are in terms of accident reductions resulting from specific safety improvements. In this study a comprehensive list of accident reduction factors were developed to use in the cost-optimization program. The development of the list of reduction factors was based mainly on a review of literature and survey of states, with limited input from a before-and-after accident analysis.
