    The newsletter includes:

    1) The 2010 Northwest Transportation Conference will be held at Oregon State University on February 9th, 10th, and 11th. The theme for the Conference is The Future of Transportation is Here, which speaks to the major shift nationally and within Oregon, with regard to energy, climate change and transportation technology.

    2) ODOT has used three methods for increasing the shear capacity of girders and cross-beams: carbon fiber reinforced polymer composites (CFRP) applied to the surface, steel bars fitted to the surface, and steel bars installed internally. However, there was no comparison of these techniques that could help engineers decide which method was most appropriate for a particular situation. Consequently, ODOT contracted with Oregon State University to compare the various repair methods, analyze the expected life, and make recommendations for repair approaches.

    3) Greenroads (www.greenroads.us/) is a sustainability performance measure under development by the University of Washington (UW) and CH2M Hill. Sustainability is assessed on new and reconstructed or rehabilitated roadways through a credit-based system.

    4) The movement of freight by truck contributes significantly to regional air pollution, and greenhouse gas emissions. According to the U.S. Department of Energy, light trucks contribute 27% of the national transportation greenhouse gas emissions and heavy trucks contribute 19% (2003). In addition, these activities have a notable impact on energy consumption and transportation network congestion; and

    5) The process of other research reports.
