In recent years, benefit-cost (B-C) analysis procedures have been widely accepted as a rational method for evaluating safety treatment alternatives. Most methods of analysis employed to date have significant limitations, overstate the severity of accidents, and are cumbersome to use. An advanced B-C analysis model that incorporates numerous modifications to enhance versatility and improve determination of accident severity is described. Basic encroachment data on which the model is based are presented, and the applications and limitations of the model are discussed. An example of the use of the model to develop general barrier use guidelines is also included.
