Research Highlights

FHWA Strategic Agenda for Pedestrian and Bicycle Transportation

Jennifer Dill
Nathan McNeil
In 2016, TREC was part of a team, in partnership with ICF and Alta Planning, that developed the Strategic Agenda for Pedestrian and Bicycle Transportation, a framework to inform future investments, policies, and partnerships and serves as the update to U.S. DOT’s 1994 National Bicycling and Walking Study. The agenda establishes a strategic, collaborative approach for making walking and rolling viable transportation options for people of all ages and abilities in communities throughout the U.S...

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
