• Abstract:
  The newsletter includes: ; 1) The recent 2008 Northwest Transportation Conference theme was “Making the Most of What We Have: Transportation Innovations for the 21st Century.” The conference was held at Oregon State University from February 5th to the 7th. Transportation professionals and researchers from around the northwest and the nation attended the conference. ; 2) In the fall of 2006 ODOT Research contracted with Oregon State University (OSU) for a study to investigate workable models to gauge the impacts of a VMT fee on different socioeconomic groups. The objective of the study is to develop models which will compare the impacts of a vehicle miles traveled (VMT) fee to the impacts of the current per-gallon gasoline tax. ; 3) ODOT is switching to pavement design based on the Mechanistic Empirical Pavement Design Guideline (MEPDG), developed by the American Association of State Highway and Transportation Officials (AASHTO). The approach described in the MEPDG is considered the state-of-the-art in pavement design. The MEPDG uses physical causes to account for the performance of the pavement. ; 4) Recent research has shown that even very small amounts of copper ions in water can significantly impair a salmon’s sensory systems. These sensory systems allow the salmon to detect and avoid predators, find food, and navigate the currents in complex stream environments. High enough levels are actually toxic to aquatic life; and ; 5) The process of some other research reports.
