The transportation network faces the possibility of sudden events that disrupts its normal operation, particularly in earthquake prone areas. As the backbone of critical infrastructure lifelines, it is therefore essential that the transportation network retains its resilience after disastrous earthquakes to ensure efficient evacuation of at-risk population to safe zones and timely dispatch of emergency response resources to the impacted area. However, predicting transportation network resilience and planning for emergency situations is an extremely challenging problem, particularly under seismic risk and uncertainty. This paper aims to propose a general assessment framework to quantify the seismic resilience of transportation network, which focuses on generalizing quantitative resilience measures of the transportation network response to earthquake rather than specifying characteristics of the corridor selections that lead to patterns of the response of each specific road segment. In the model, traffic capacity is selected as the quantitative resilience measure and a Fuzzy Logic evaluation system is integrated to address seismic risk and uncertainty throughout the entire transportation network. Finally, an illustrative example was provided to present the potential of the proposed framework as an effective evaluation tool to gauge the resilience of transportation network and also highlight its weakness.
