Design of collaborative multimodal strategies for disruption management in urban railway systems

In order to increase the attractiveness and the resilience of multimodal transport systems, each transport mode should be exploited according to its peculiar characteristics in an integrated way with the other modes. In this regard, it is possible to imagine a “synchromodal framework” relying on a “rail backbone”, where the synchronization of the different modes is driven by rail transport. On the other hand, the limited number of path alternatives that characterizes the rail network makes it vulnerable to service disruptions and may result in a significant Level of Service loss. In this context, this paper proposes a methodology for urban public service providers that allows to design a multimodal service able to react, in a quasi-real-time framework, to unexpected events by offering multimodal transport solution to users.
