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. Numerous methods can be used to accomplish this, but the (Social) Cost-Benefit Analysis is mostly applied in the context of traffic safety. However, this method requires monetary inputs for its mathematical process. Unfortunately, in the context of traffic safety, non-monetary elements are also very important. 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: the Multi Actor Multi Criteria Analysis (MAMCA) developed by Macharis (2004). This technique possesses an additional characteristic which can also create a surplus value in certain evaluation situations: it allows for structured stakeholder participation during the entire process. The MAMCA is a decision tool that enables the policy makers to take into account all the different aspects of a problem at the same time. Different alternative solutions to a problem get evaluated according to multiple criteria, eventually determining which one of them is the preferred option. The method does not replace the policy maker, but allows him to come to a judgment in an underpinned manner. To indicate the surplus value of the MAMCA in the traffic safety context, a case study will be presented. In this study, the proposed alternatives contain numerous non-monetary elements and the inclusion of different stakeholder groups is preferable to achieve reliable and useful results. Based on the characteristics of this case study, the advantage of using the MAMCA for specific traffic safety problems becomes very clear.
