The starting point for a program of local safety improvements is the preparation of a list of sites with promise at which to conduct a detailed engineering study, by which cost-effective projects can be identified. Inclusion on the list depends on the criteria used for ranking sites. Five alternative ranking criteria were compared by the cost-effectiveness of the projects to which they lead. It was found that sites at which most accidents or most severity-weighed accidents are expected lead to most cost-effective projects.
