Risk analysis for hazardous material transport by road: case study on Tangier-Tetouan region, Morocco

— From a System of System (SoS) perspective, quantitative risk assessment in hazardous material transportation presents several specific criticism. The Quantitative Risk Analysis (QRA) methodology requires elaborating large amount of data to estimate the frequency and the consequences of each accidental scenario which involves hazardous material. In this paper, a Quantitative Risk Analysis methodology dedicated to hazmat road transport based on simplified approach is presented. The frequency analysis is realized by considering preselected event tree schemes for hazmat product. The consequences analysis is based on the innovative Speditive method to compute impact areas. Societal risk measures have been performed to compare the risk to transport gasoline by tank trucks covering two alternative paths from the Med Tangier Port to Tangier in the Tangier-Tetouan region, in Morocco.
