Research Highlights
Evaluation of Different Curb Extension Treatments for Pedestrian Comfort and Safety at Intersections
Nathan McNeil
Sirisha Kothuri
In a project funded by the The District Department of Transportation (DDOT), Portland State University is partnering with the University of North Carolina at Chapel Hill to document and identify factors associated with road user safety and comfort at intersections with permanent versus tactical (both with and without mural art) curb extensions, as well as a set of control locations with no curb extensions. DDOT has over the last few years installed several curb extension treatments on differe...

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...
