PTV is concentrating on the development of a procedure to determine the operational vulnerability of underground public transport stops, including their significance for the overall network. The method is based on macroscopic transport demand models. It is also embedded in an overall process that includes vulnerability assessment from the building and user's point of view. The overall procedure forms the basis for increasing the resilience of public transport systems. PTV is also working on the question of whether and to what extent new forms of mobility can be used in the event of a damage to the public transport system, in order to prepare modal shifts and to mitigate the effects of the breakdown.
