This paper describes an object-oriented software tool for performing safety assessments of roadway designs. Safety assessments are used to estimate the effect of changes in roadway characteristics like horizontal curvature, travel speed, and the position of fixed objects on the safeness of the roadway. The Safety Advisor provides a structure for representing probabilistic models of accident risk. These models are parsed as input allowing the user to modify the fundamental basis of the software tool without changing the source code. These models are represented as objects that can be easily changed by the user to reflect local needs, user preferences or new policy. A brief description of the software, its design and its use are presented.
