Importance of freight transportation is recognized universally by all states and it is particularly an important component of Oregon’s economy. Many sources estimate that freight shipments will nearly double in 10 years. While other modes are clearly important for freight transportation, trucking is the dominant mode in terms of tons and value. Monitoring freight movement and freight transportation performance is essential in making effective policies and informed decisions to enhance and eff... Read More

Future Flooding Impacts on Transportation Infrastructure and Traffic Patterns Resulting from Climate Change

Climate change in the Pacific Northwest of America is likely to bring more frequent, heavier winter precipitation as temperature rises. These changes in precipitation patterns have significant implications in hydrology and socioeconomic sectors that could be affected by changes in hydrology. Transportation infrastructure and travel patterns are also vulnerable to potential changes in runoff regimes and stream geomorphology. The 2006 and 2007 winter storms resulted in massive flooding, caus... Read More
