Abstract: Climate change may be the most serious and urgent issue facing the transportation sector. Transportation is both a major producer of greenhouse gas (GHG) emissions and is also vulnerable to the consequences of climate change. Major reductions in GHG emissions from the transportation sector will be needed in order to avoid the most serious effects of climate change. Travel models can play an important role in evaluating strategies for reducing transportation sector GHG emissions, but prevailing travel models do not address a number of factors that significantly affect GHG emissions. The GreenSTEP model was developed to fill this gap. The model estimates household level vehicle travel, energy consumption, and GHG emissions. GreenSTEP is currently being used to assist the development of ODOT's Statewide Transportation Strategy for reducing GHG emissions and Metro's Climate Smart Communities scenario planning process.

Speaker Bio: Brian Gregor is a senior transportation analyst for the Oregon Department of Transportation (ODOT) where for the past 15 years he has worked on a variety of transportation and land use modeling and analysis projects. He is the principal developer of the GreenSTEP and Land Use Scenario DevelopeR (LUSDR) models. He has also worked on the development and application of Oregon's Statewide Integrated Model (SWIM), lead the automation of ODOT's modeling processes using the R programming language, and authored several reports on congestion and commuting in Oregon. Previously, Brian worked as a local land use planner and as an environmental analyst, region planner, and transportation and land use policy specialist at ODOT. In the latter role, he developed ODOT's State Agency Coordination Program and worked with the Department of Land Conservation and Development (DLCD) on writing the original Transportation Planning Rules. Brian is a registered professional traffic engineer and has a master's degree in urban and regional planning from the University of Oregon.
