Research Highlights

Developing Data, Models, and Tools to Enhance Transportation Equity

Amy Lubitow
Julius McGee , Raoul Liévanos
Data from travel surveys are used to forecast demand, inform transportation investments, and craft urban policies. Because these data are so essential to shaping our transportation system, it is critical that hard-to-reach populations—such as low-income, minority, and transit-dependent people—have their travel behavior accurately reflected. The limited survey coverage may lead to inaccurate estimation of their transportation access and behavior, impede policy changes related to transportation... Read More

Examining the Geotechnical Earthquake Hazard to Transportation Assets in Oregon and Washington: Characterizing Earthquake-Induced Deformations of Silt Soils

Diane Moug
Critical transportation infrastructure in Washington and Oregon is vulnerable to damage during strong earthquake shaking, including the anticipated magnitude 9 Cascadia Subduction Zone event. A major hazard to transportation infrastructure is the failure and deformation of the underlying soil. Soils can undergo large deformations and strength loss when subjected to strong earthquake shaking. Current engineering practice has established guidance for estimating earthquake hazards for clay and s... Read More
