Performance measures calculated by REDARS include congestion and delay times.
Refining the REDARS program's current loss estimation methodologies is included, along with providing a comprehensive assessment tool to measure highway resilience.

Therefore, beginning in the late 1990s, FHWA sponsored multiyear seismic research projects for developing and programming REDARS (Risks from Earthquake DAmage to Roadway Systems) software, released for public use in 2006.
REDARS is a multidisciplinary tool for seismic risk analysis of highway systems nationwide.
REDARS incorporates these traffic states into a highway network link-node model to form a set of system-states that reflect the extent and spatial distribution of roadway closures at various times after the earthquake.
