An Online Visualization Tool for Assessing the Robustness of Multimodal Transport Networks in Case of Extreme Weather Events and Natural Hazards

Abstract

The impacts of extreme weather events (EWE) and natural hazards (NH) on multimodal transport networks have lately gained increasing attention, due to the ongoing change of climatic conditions, to which such events are often attributed. Research efforts in this direction mostly address the cost quantification of these impacts. Yet, to the authors’ knowledge, little has been reported in the literature regarding the impacts of such events on flows for individual transport modes. In the framework of this paper, a recently developed methodology for analyzing the effects of EWE and NH on passenger flows and identifying cross-modal substitutability opportunities between transport modes at transnational level is briefly presented. An online visualization tool for the application of this methodology is presented. The tool is targeted towards all related entities and relevant stakeholders, as well as towards researchers and individual interested users. Its aim is to provide visual information on occurrence probabilities of EWE and NH, climate change related projections, information on transport networks and visual representations of substitutability opportunities between modes.
