A paper titled ‘Is road safety management linked to road safety performance?‘ co-authored by Eleonora Papadimitriou and George Yannis is now published in the Journal of Accident Analysis and Prevention. Quasi-Poisson models and Beta regression models are developed for linking road safety management indicators (estimated on the basis of Categorical Principal Component Analysis ) and other indicators (i.e. background characteristics, etc.) with road safety performance (mortality and fatality rates, SPIs, composite indicators, etc.).

The results of the analyses suggest that road safety management can be described on the basis of three composite indicators: “vision and strategy”, “budget, evaluation and reporting”, and “measurement of road user attitudes and behaviours”. More-over, no direct statistical relationship could be established between road safety management indicators and final outcomes. However, a statistical relationship was found between road safety management and SPIs, which were in turn found to affect ‘final’ outcomes, confirming the SUNflower approach on the consecutive effect of each layer.
