New Mobility For All: Can Targeted Information And Incentives Help Underserved Communities Realize The Potential Of Emerging Mobility Options?
Nathan McNeil
John MacArthur
Low-income residents, immigrants, seniors, and people with disabilities – these are people who stand to gain the most from new tools and services that reduce transportation costs and travel time. However, issues of affordability, technology adoption, banking access or other barriers can limit access to these new mobility opportunities.
In the latest report funded by the National Institute for Transportation and Communities (NITC), New Mobility For All: Evaluation of a Transportation Incent...

Bridge Pile Foundations Subjected to Liquefaction-Induced Lateral Spreading
Arash Khosravifar
The overall goal of this research is to improve the seismic safety and resiliency of highway bridges in the Pacific Northwest during earthquakes. Past earthquakes have shown that liquefaction-induced lateral spreading can be a major cause of collapse for pile foundations. Bridge engineers generally agree that pile foundations must be designed for: (a) lateral spreading loads caused by liquefaction of soils adjacent to piles, and (b) inertial loads during shaking resulting from the superstruct...
