Title: New Measures for Quantifying Importance of Links in a Transportation Network
Accession Number: 01631458
Record Type: Component
Abstract: Transportation networks are vulnerable to natural disasters such as floods, tsunamis, earthquakes, etc. Interdependencies between the transportation system and other critical infrastructures necessitate the need to protect it to achieve system resiliency. In order to increase a network’s resiliency, the important links need to be identified. This study proposes two new measures to quantify link importance. It extends previous work by considering the extra distance traveled by road users when a link is disrupted, the traffic volume (AADT) on the disrupted link, and the economic losses due to loss of the link. To assess the effectiveness of the proposed measures, they are applied to a transportation network in South Carolina using data from a recent 1000-year rainfall event.
Supplemental Notes: This paper was sponsored by TRB committee ABR10 Standing Committee on Critical Transportation Infrastructure Protection.
