Road safety management? Operations research approach

This paper proposes that an operations research approach to road safety management can improve the efficiency of the road safety system. A road safety management model is presented in this paper, which incorporates the findings of documented research, published primarily in the areas of engineering and enforcement. The model specifically uses linear programming as an operations research tool to assess the effectiveness of different road safety measures, while taking account of the constraints imposed by limited human / financial resources. The advantage of using an operations research approach is that it provides a scientific basis for establishing and monitoring quantitative road safety targets. A further advantage of the proposed model is that it can be applied at national, regional or local levels. The model in this paper describes a method for combining the effects of different road safety measures and provides an optimal solution to the linear programming task. As an example, the model is applied to the inter-urban road network in Cork, Ireland. The optimal solution is presented in terms of the number / severity of accidents prevented over a specific timeframe and the resultant monetary benefits associated with the prevention of these accidents. The effects of implementing further road safety resources are also examined in the context of the model, which provides road safety managers, and ultimately policy makers, with a means to investigate the effectiveness of different road safety strategies.
