An application of the likelihood/Bayes approach to the estimation of safety countermeasure effectiveness. For presentation at the Annual Meeting of the Transportation Research Board, Washington, D.C., January 1983.

In another paper (Hauer, 1983) preference has been stated for the use of the likelihood function as a device for the accumulation of empirical evidence about the effect of safety countermeasures and for the Bayesian approach as a tool for presenting information to support rational decision making. The purpose of this paper is to illustrate the use of the aforementioned approaches in a concrete case.
