REDARS
Since the mid-1990’s, MCEER’s investigators have collaborated on the development of a new methodology for the analysis of earthquake damage to highway systems. This research has led to the release of REDARS 2 (for Risks due to Earthquake DAmage to Roadway Systems), a public-domain software package that accounts for how earthquake damage affects post-event traffic flows and travel times, and estimates losses from these travel-time and traffic-flow impacts. This software can be used to guide pre-earthquake planning and assessment of seismic improvement options as well as post-earthquake response in real time after an actual earthquake. Features include
post-earthquake congestion-dependent trip demands analysis, an“import wizard” to ease input data preparation, and a “decision guidance”
model to to guide seismic risk
reduction decision making.
