Uniform Risk Assessment in the Swiss Road Network

The aim of this research project is to develop a decision framework and a methodology to identify the appropriate and efficient use of limited resources in the society, in regard to the achievement of an acceptable level of safety for the highway network in Switzerland. In different application areas many different methodologies and approaches of risk assessment and risk management have been developed, each one adapted to the specific situation. Thus the assessed risks are not comparable amongst the different application areas.
For comparing and judging the risks in the different application areas, the development of a standardized methodology for risk assessment is of utmost importance. Such a methodology has to be applicable to all decision situations and to all application areas in the highway network. It has to facilitate the consistent assessment of risks and the establishment of acceptance criteria.
