TNO decision model for the transport or hazardous materials through road tunnels
conference paper
Although transport of hazardous materials is supposed to be safe [CTGG, 1992] it still is associated with risks. The transport of hazardous materials requires therefore specific attention in order to meet safety standards. One important aspect involves risks to the public. The application of tunnels for transport purposes is being considered in various cases. The risks for road users on the tunnel route, however, will increase and the possibility of irreparable damage to the tunnel exists. On the other hand transport of hazardous materials via diversions will increase the risks to the public, as diversions usually are closer to residential areas than are highways with tunnels. Here a decision problem arises. The key question is: which route is, for a specific location, preferable for transporting hazardous materials, or certain classes of them, and is the transport of these materials acceptable in terms of risk? In order to support policy and decision makers in finding the 'best' answer TNO has developed a deci-sion model. Quantitative risk analysis is used to calculate the risks involved. The out-come of these calculations define the category of the decision problem. The present TNO decision model has demonstrated to be a powerful tool for deci-sion-making processes on transport of hazardous materials through road tunnels. It already has been applied to several road tunnels in The Netherlands.
