Equity Outcomes and Potential for Better Bike Share
John MacArthur
Nathan McNeil
In a mere ten years, public bike-sharing systems have exploded from operating in a few select European cities to expanding in North America at a pace of nearly two dozen cities per year in recent years. The majority of academic research to date has focused either on the complex logistics of designing and operating systems or else on broad comparisons across systems. Investigations of system users and local impacts have only just begun. As cities plan and launch their systems, a tension has ar...

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...
