System dynamics is a computational modelling method that is used to understand the dynamic interactions influencing behaviour in complex systems. In this article we argue that the method provides a useful tool for ergonomists wishing to model the behaviour of complex systems. We present a system dynamics model that simulates the behaviour of a drink driving-related trauma system and explore the potential impact of different road safety policy interventions. The model was simulated over thirty-year periods with different policy interventions. The findings suggest that the greatest reduction in drink driving-related trauma can be achieved by policies that integrate standard road safety interve..
