An efficient and safe transportation system is essential to communities during the long-term recovery period after earthquakes. A disrupted transportation network due to infrastructure damage or failure affects the functionality of the traffic system and poses increased traffic safety risks. A rational...
The study aimed to understand the impacts of extreme climatic conditions such as prolonged droughts and intense precipitation due to climate change on the resilience of civil infrastructures like embankments. The knowledge of unsaturated soil mechanics and soil chemistry is integrated to determine the...
A new method for building seismically resilient bridges is proposed using accelerated bridge construction (ABC) methods. The hybrid two-column bridge bent consists of post-tensioned precast concrete columns with a buckling restrained brace (BRB) as an external energy dissipation device. The design of...
An efficient and timely rescue of injured people by emergency medical services (EMS) is essential to saving as many lives as possible following disasters. Disrupted traffic networks due to the failures of transportation infrastructure (e.g., bridges) following major disasters like earthquakes affect...
Redundancy is vital for transportation networks to provide utility to users during disastrous events. In this project, we develop two network-based measures for systematically characterizing the redundancy of transportation networks: travel alternative diversity and network spare capacity. The travel...
