Governments are taking diverse measures to achieve higher road safety and less traffic casualties. These initiatives need to be evaluated for their effectiveness and efficiency. Several methods may be used for this purpose, but the (Social) Cost-Benefit Analysis is mostly applied in the context of traffic safety. This method requires monetary inputs for its mathematical process. In the context of traffic safety, however, a number of non-monetary and strategic elements may also play an import role in the decision-making process. Therefore, we present another technique, which does not require money values but is able to work with all types of quantitative and even qualitative inputs, namely the Multi-Actor Multi-Criteria Analysis (MAMCA) (Macharis, 2000). Another characteristic of this method is that it allows for structured stakeholder participation during the entire process. This is an important advantage, since it can create a high surplus value in specific decision making situations. The MAMCA is a tool that enables policy makers to take into account simultaneously the different aspects of a problem. Alternative solutions to a problem are evaluated according to multiple criteria corresponding to stakeholder objectives. By doing so, it is possible to determine which one of these solutions is the most preferred one in terms of the community of stakeholders. The MAMCA is designed as a method for “decision aid”. It does not replace the decision makers, but helps them to come closer to a solution which is preferred by the majority of stakeholders. To illustrate the surplus value of the MAMCA in the context of traffic safety, a case study will be presented. In this study, a number of non-monetary and strategic issues play an import role in the evaluation process. The strategic issues will be studied using a multi-stakeholder perspective and it will be shown that, by doing so, more useful and reliable results may be obtained.
