An agent-based micro-simulation framework to assess the impact of river floods on transportation systems: implementation trajectory for an assessment in the Brussels metropolitan area

Several studies were made to assess the direct damage but few studies tackled the topic related to the assessment of indirect damage. This paper discusses the development of a large scale agent-based micro-simulation framework to assess the economic damage caused by river floods. The advantage of this approach is that the economic loss can be assessed at individual level. For that purpose, relationship is established between costs and trips cancelation/duration growth. As the numerical simulations depend largely on the initial demand, the accuracy of the data is fundamental. The model is based upon several disaggregated data related to mobility behaviour of the Belgian citizens. The study area covers the Brussels metropolitan area which was subjected to several floods in the past and may see the risk increasing in the coming decades.
