Proactive Measuring of Road Safety - ProMeV : background, methods and substantiation of choices. Lack of reliable crash data was one of the reasons to explore with regional authorities the alternatives that can be used as a basis for road safety policy. In addition to crash data, intermediate road safety indicators — the so-called ' Safety Performance indicators (SPIs) or risk factors —appear to offer interesting starting points for policy makers. Policy makers can use these SPIs to identify problems, prioritize and to formulate policy in a more risk-based and proactive manner. Risk-based in this case means: focusing on situations, groups, or locations that are more hazardous than others. These developments and insights have been reason for the Association of the Provinces of the Netherlands (IPO) to commission SWOV to develop a proactive instrument to make policy choices for the layout of roads and the road network. It was also required to make use of the best possible scientific evidence-based methods. The project was called Proactive Measuring of Road Safety (ProMeV). The ProMeV instrument was initially developed based on existing proactive methods for policy prioritization. ProMeV not only contains methods for the analysis of infrastructural problems, but also of hazardous traffic behaviour that is evoked by the design of the road or road network. Furthermore, suggestions are made about how to implement citizen participation in ProMeV.
