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