Infrastructure and Safety in a collaborative world. Road Traffic Safety pages:23-42
This chapter briefly describes the basic principles of multi-criteria analysis (MCA) and cost-benefit analysis (CBA), in view of their application to the socio-economic evaluation of different scenarios for improving road safety. The specific scenarios for improving road safety by creating a more forgiving road (FOR) and self-explanatory road (SER) environment are, however, identified in subsequent chapters of this book. As regards MCA, the multi-actor MCA (or MAMCA), as well as the analytic hierarchy process (AHP), are discussed in more detail. As re-gards CBA, special attention is given to the definition of specific decision criteria. Special attention is also given to possible approaches to cope with lacking data on safety impacts. By the end of this chapter it should be very clear which are the dif-ferent interpretations to be placed on the results of CBA and MCA, even in cases when these results are conflicting.
