The urbanization process growing rapidly during the latest several dozens of years leads to proliferation of infrastructurally complex territories. At the same time, growing interaction of critical infrastructures in combination with the increased frequency and scales of anomalous natural processes result in the growth of the intersystem failures. Preliminary studies demonstrated possibility of intersystem accident classification based on topology of cascade process. The same classification should be constructed for infrastructurally complex territories, because a type of territory (quality and quantity of critical infrastructures, square of territory and etc.) strongly impacts on occurrence and development intersystem failures. Flow-based approaches used for modeling of intersystem accident. The main problem of quantitative risk assessment of intersystem accidents is connected with transfer function of network interconnection node description. Each node of network interconnection can possess own transfer function (stepped, continuous, mix behavior). The given paper is devoted to the problems of infrastructurally complex territories classification and some proposals for quantitative risk assessment of intersystem accident for different types of territory and set of impact transfer function
