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… Read More

Human Wayfinding

Amy Parker
The Tri-County Metropolitan Transportation District Of Oregon (TriMet) is in need of specialized support to improve and promote effective resources in human wayfinding and navigation at its transit centers. Areas of need include, but are not limited to: 1. Tactile Maps: Providing tactile spatial information accessible to people who are blind or low vision. 2. Written descriptions of stations and routes: information needed by people who are blind or low vision, to allow independent… Read More
