This ETSC review on transport safety organisation differs from many of its predecessors. Although it is dedicated to the same kind of policy-oriented reviewing process that has framed all former reviews, this review seeks to be more explanatory by opening up the "black box" of the organisation of safety as well as safety in organisations. It invites safety experts and policy-makers alike to think beyond the boundaries of their disciplines and policy areas. With a cross-modal, inter-disciplinary perspective on transport safety organisation this review should provide a sound initial reference point for future actions in this area. It is grounded in the conception that safety policies will deliver higher scores if they are able to mobilise their inherent synergies and thus lead to even better safety practice.
