| Popis: |
Transports of substances to or from Seveso classified facilities are always a dangerous link in today’s industrial societies. Despite the risk of serious accidents, it is common that these transports use routes that pass through densely populated urban areas. We present a computational concept employing a multi-model simulation platform that allows for simulation of diverse scenarios. This platform allows us to simulate severe incidents in a city including leakage from either a stationary or moving transport vehicle, dispersion of the released substance, and finally the injury panorama of the affected population. Different scenarios of leakage are studied in combination with various environmental conditions regarding parameters such as wind strength and direction. The dispersion model utilizes a synthetic 3D model of the city in which the wind driven convective fields spread the released substance. In this model, a large number of virtual habitants are allowed to walk on the streets following individual paths while obeying a set of predetermined rules of behaviour. Each individual accumulates an individual dose of the agent by inhaling the harmful substance and is subject to injury scaling from no harm at all to lethal injury. The total expected injury panorama of the population in the city, for the current scenario, is finally obtained from the statistics of the synthetic actors that represent the real population. |
