Community Resilience Evaluation including interdependencies

Abstract

This paper presents a development of PEOPLES methodology to evaluate the functionality and the resilience of the transportation system, considering the interdependences between and among systems, categories, and dimensions, during extreme events. The proposed methodology considers the redundancies and the interdependencies during the entire process of damage and of recovery. The accessibility of a transportation network (and consequently to buildings units influencing their functionality) form the transportation sources is the main parameter that defines the functionality of the transportation system. This method was implemented in a software that is able to evaluate the damage state and the resilience of the road network and of the building system of a community. It provides to evaluate a recovery plan that maximizes the resilience index respecting the physical (accessibility), social, and economic limitations. Finally, the software has been tested using a case study of Treasure Island in San Francisco considering a probabilistic earthquake’ risk assessment.
