Transportation network resilience: Evaluation of performance measures

Jessica L Miramontes, University of Texas at El Paso

Abstract

The resilience of an urban transportation network is its ability to adapt, absorb, anticipate, and rapidly recover from a disruptive event causing link closures, node closures, and reduced capacity, while providing an acceptable level of service. Several researchers, have performed studies of Transportation Network Resilience (TNR). However, there has not been a clear definition of how to measure or quantify TNR. The objective of this research is to define, quantify and compare the consistency of different measures of TNR and make recommendations to engineers and decision makers. In this research seven proposed parameters have been defined as candidate measures of TNR. A simulation-based transportation network modeling software has been used to model the El Paso’s highway network. Different links in the network were closed for a certain period in 20 simulation scenarios. For each of the defined TNR measures, the calculated TNR values from the 20 simulated scenarios were ranked in order of their negative impacts. Based on the analysis performed, the TNR measures that are consistent in their ordered lists are queue length and frontage road delay and are therefore recommended as the preferred TNR measures. Total network delay, one of the candidate measures, has been recommended for further studies. ^
