Although it is widely claimed that Oregon's economy is dependent on freight movement, economic activity in Oregon has decoupled from physical goods movement. Truck traffic per unit of gross state product has fallen, and even the loss of regular container service to Portland has had no measurable effect on the region's economy.
Oregon's economy has shifted away from freight intensive industries and now depends on knowledge...

As urban areas across the country are investing in bicycle and pedestrian infrastructure to promote environmentally sustainable transportation and to develop livable communities, many have pointed to improvements in environmental quality, economic development and public health as potential positive outcomes. While these outcomes of active transportation infrastructure are relatively well documented, it is also known that both transportation and environmental...

Abstract: The ability to fully understand and accurately characterize freight route choice is one that will support freight modeling frameworks, and regional and state transportation decisions. This ability, when combined with regional and state commodity flow data, can compose an effective statewide freight modeling framework. Typically, transportation network models take a shortest path assumption for truck routing both for strategic and operational routing decisions. The goal of this research was to determining how different subgroups of shippers, carriers, and receivers make route choices, and to understand how these approaches vary across types of routing decisions. We consider route changes of both a spatial and temporal manner. This talk presents the results of a survey of over 800 shippers, carriers, and receivers in Washington State, and recommends a framework for improving the modeling of routing decisions in existing network models.

Abstract: Coal-fired electricity plants account for over 50 percent of the nation’s electricity. These plants can purchase coal from a large number of different locations and, often, can have a number of different transportation options. Normally, however, from the array of different options, they use only a handful. We frame the model as that of a cost-minimization with a large number of input choices, characterized by standard Kuhn-Tucker conditions. Empirically, we estimate a system of input decisions that contain both zero and non-zero levels, using a Multiple Discrete/Continuous Extreme Value model. The payoffs from each choice are a function of costs, coal attributes, and unobserved modal attributes, as well as the increased regulation under the Clean Air Amendment Act of 1990.
