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

Heejun Chang
Martin Lafrenz , Miguel Figliozzi
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

Distribution Logistics Course

Miguel Figliozzi
Commercial vehicle movements associated with the delivery of goods and services are currently experiencing a number of challenging problems. Carriers and fleet operations face congestion, a growing number of tolls, increasing service level demands, and in some cases opposition due to the externalities caused by freight traffic in urban areas. This course will provide a greater understanding of the complex issues surrounding urban freight and logistics and it will be relevant to graduate stude... Read More
