摘要

The paper presents a concept for the integration of resilience assessment aspects into a life cycle management for transport infrastructure. A subsequent assessment of the resilience of the road infrastructure allows appropriate measures to be applied at the critical locations, thereby ensuring the availability and safety of the transport infrastructure. To promote the practical application of the assessment procedures, the development of a web based geographic information system (GIS) tool is proposed to enable the linking of all relevant data at network and object level. In this way, available information on potential hazards (e.g. through flood hazard maps) in combination with a criticality assessment of the road network and the associated function of the bridge and engineering structure can support the prioritization of resilience measures. For owners and operators of road infrastructures, such a GIS tool would offer the possibility to combine all relevant information for the assessment of the considered road infrastructure - on object and network level. Starting on network level with a criticality analysis in order to identify the critical infrastructure objects which can be better protected according to the result of a resilience assessment on object level. As a result, appropriate measures are proposed in order to increase the resilience of the road infrastructure. All the available data can be quickly analysed and visualized as well as redundant data storage can be avoided or at least reduced.
