Identification and implementation of performance indicators can improve existing assessment methods within the transport infrastructure management system.

In this contribution it could be shown how to characterise and systematise performance indicators for bridge structures and tunnel systems. Systematised performance indicators for bridge and tunnel systems were presented and a case study was used to show how performance indicators can be coupled with risk-based performance requirements, data-informed performance assessment methods and inspection and monitoring concepts.
