This deliverable gives an outline of the process of prioritising road safety measures. It should be used by policy makers to understand what they can do to choose between different countermeasures. The deliverable is meant to give an overview, rather than technical details. For details the readers are referred to other deliverables. The prioritisation process starts with establishing the effectiveness of a measure. Different approaches to investigate the effectiveness are given with practical examples. For the economic efficiency evaluation, three methods are described (cost-effectiveness, cost-utility, and cost-benefit analysis). It is explained why the approach chosen for the SafetyCube Decision Support System is the cost-benefit analysis. It is acknowledged, however, that data to perform a full-scale cost-benefit analysis are not always available. Therefore, multicriteria analysis is discussed, a group of systematic tools for decision making that can also be based on categorical input values. The remainder of the deliverable is focused on how the economic efficiency evaluation is implemented in the SafetyCube DSS. It is explained which input SafetyCube provides and how users of the system can either adjust the SafetyCube analyses to their own situation or conduct new analyses. (Author/publisher)
