Abstract
Priorities for remedial treatments are traditionally determined on the basis of accidents and accident savings. However, low or non-existent accident numbers make accident savings and treatment priorities difficult to quantify. This report describes initial research aimed to assess the potential for the application of the methods of modelling risk scenarios that have been developed and used by risk engineers in other fields such as chemical, aerospace and industrial engineering. One primary purpose was to establish a firm theoretical foundation for such models by defining the necessary terms and model structures appropriate to the physics of road crashes. The core of the general form of a risk model for road safety is presented. (A)
