How can community members become more engaged in transportation decision making?
Individuals and groups can learn to effect powerful change, but success requires some familiarity with how civic processes work. Community Transportation Academies, or CTAs, provide a basic technical understanding of how a city or region’s transportation system operates, along with the decision makers and decision-making processes that determine how the system is shaped.

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...
