Development of a best practice methodology for risk assessment in roadway tunnels (ASTRA2009/001)
Overview
Background & policy context:
According to the directive 2004/54/EC of the European Parliament, all member states should have detailed and clearly defined methods for risk analysis in road tunnels at the national level.
Objectives:
The main objective of this research project is the development of a best practice method for road tunnel risk assessment under normal traffic situations. The method represents the current state of the art in the field of risk based decision making and in the field of traffic engineering, especially in the field of modelling of traffic accident frequencies and the consequences of accidents in road tunnels. The method is generally applicable to all road tunnels but it specifically takes into account the needs, regulatory requirements and tunnel layouts, which have been identified to be relevant for Switzerland and Norway. The method is easy to apply and supports typical life safety-related decisions during the planning, operation and maintenance of road tunnels.
Methodology:
Basics for the project provide the studies provided in last time period and the expertise of the research team in the field of probabilistic modelling and tunnels risk analysis. In addition, data from the Norwegian and Swiss road administrations are available that are considered in the development of the risk model.
