A methodology for road traffic resilience analysis and review of related concepts
article
Major and minor disturbances can have a considerable impact on the performance of road networks. In this respect, resilience is con-sidered as the ability of a road section to resist and to recover from disturbances in traffic flow. In this contribution, an indicator is pre-sented, the Link Performance Index for Resilience (LPIR), which eval-uates the resilience level of individual road sections in relation to a wider road network. The indicator can be used to detect poorly resilient road sections and to analyse which underlying road and traffic characteristics cause this non-resilience. The method adds to related concepts such as robustness and vulnerability by also con-sidering recovery from congestion events explicitly and by focussing on everyday operational traffic situations rather than just on disas-ters or major events. The LPIR is demonstrated in an experimental case on a real network in which the effectiveness of the method is demonstrated.
