This webinar explores a new method to assess trip resilience of the road network following a major incident/disaster, integrating all dimensions of resilience, namely Trip Robustness, Trip Redundancy, and Recovery. The proposed measure provides an opportunity for decision-makers to estimate and rank the trip resilience between each (group of) Origin-Destination pair(s) using pre- and post-incident flow and travel time. This new method can be applied to support the increase of trip resilience in transport infrastructure, to assist with the prioritisation of proposed resilience mitigation measures in a constrained financial environment, typical of most road agencies, and to determine the relative criticality of particular road links.
Two case studies, one in the South Island of New Zealand (national level) following hypothetical earthquake and one in Auckland Harbour Bridge (AHB) following the major incident, would be presented to verify the practicality of the method.
