Priorities highway accident sites: A data envelopment analysis model

This paper presents an optimisation procedure for prioritising highway accident sites. The methodology (data envelopment analysis) takes into account the multidimensional nature of the problem. Specifically, it recognises that different accident types on a road section should be credited with different weights, but permits such weights to vary (within reasonable limits) from section to section. The methodology also permits the inclusion of multiple inputs on the resource side, including not only the cost of repair, but factors such as driver inconvenience.
