This paper describes a management tool for identifying the optimal mix of road safety interventions to achieve a given target at minimum cost, or alternatively to maximise safety for a given budget. The tool embodies a computable simulation model to predict the road safety outcomes of a user-specified set of interventions.Though not an optimising model (it does not formally identify the optimal mix of interventions), it can be used in an exploratory mode to seek the optimum.It differs from most other predictive models in two main ways. First, it explicitly represents road safety interventions in considerable detail. This means that agencies can use it to explore whether particular interventions are justified, where and to what intensity. Second, it uses standard datasets and software, which makes it readily adoptable by most road safety agencies in developed countries.(a) For the covering entry of this conference, please see ITRD abstract no.
