ROAD TRANSPORTATION OF DANGEROUS GOODS - QUANTITATIVE RISK ASSESSMENTAND ROUTE COMPARISON

Transportation of dangerous goods (TDG) by road creates risk for the p eople present on and along the routes (road users and surrounding popu lation). To minimise them, is it better to have TDG going through a ci ty or on the contrary by a longer detour through less populated areas? The choice is not always easy. It may become very difficult when the detour goes through tunnels. There, accidents may have developments an d consequences very different from what might happen on an open air ro ute. To make the right choice it becomes necessary to use a QRA (quant itative risk assessment) approach dealing with the accident scenarios likely to occur, their probability and possible consequences. It may b e useful to identify the DG (dangerous goods) classes which contribute most to the risk and examine the interest of nonuniform strategies, i .e., different routing for certain DG.
