Abstract
All the models that I have described and defined originate from the classical definition of technological risk, specifically of accidental risk, that is related to human activities. The risk I have dealt with is so related to the failure – or accident – either of a vehicle on road or a pipeline, transporting dangerous goods (DG). Although different means of transportation do not deeply influence the basic definition of risk (which is more affected by the quantity, the type and the nature of the transported dangerous good), different methodological approaches may be used to evaluate the risk in transportation. In Chapter 1, some preliminary basic concepts on industrial risk, its assessment and its characterisation in the transportation and logistic domain are introduced. On the ground of the basic assumption that “an accident may happen” both in road and in pipeline transportation, in Chapter 2 I have defined what a DG is, which type of DG I have considered in this study, which transportation modalities are generally used, and which of them I have chosen for my research activity, and finally, what the main relative regulations are present in France, Italy and in general in Europe. Chapter 3 deals with the risk definition in the transportation of DG, respectively, in pipeline and on road, starting from one risk definition, univocally based on the risks related to human activities. Similarities and differences between pipeline and road transportation risk definition are also discussed. Then, in Chapter 4, an original methodology used to describe pipeline risk assessment has been defined and validated on a case study. In Chapter 5, an innovative and technological real-time approach which can be used to describe the effects of a DG accident scenario on road, and the population involved, has been described. Finally, I tackle specific models and methods of risk assessment and control in DGT on road, considering two different approaches: a risk adverse decision maker approach (Chapter 6); and an optimal real-time control of DGT flow towards a critical infrastructure, such as a tunnel (Chapter 7). Conclusions and future developments are reported in Chapter 8.
