Abstract

A computerized benefit-cost model, developed for the Federal Highway Administration, can be used to evaluate alternative accident reduction countermeasures. The model was designed for use by state highway departments and is capable of evaluating both countermeasures that increase frictional supply and countermeasures that reduce frictional demand. Emphasis was placed on compatibility with typical highway department practices and the capability to provide fair comparisons, in an economic sense, between alternative countermeasures. The model incorporates relationships between skid number and accident rate obtained from an extensive data collection and analysis phase. The effects on accident rate of factors other than skid number are based on the literature. A tested version of the computer program should be available from the Federal Highway Administration in the near future.
