The transportation of logs from the forest to the mill accounts for 25-50% of the delivered cost of wood, depending mostly on haul distance. Decision support systems (DSS) for log truck scheduling and dispatching have the potential to reduce transportation costs by optimally constructing routes, also known as schedules for...
The gasoline tax, the main source of highway revenue is no longer a viable source of
funding to maintain the existing highways. Many states in the United States are
already using revenues from other sources such as sales tax and income tax to fund
new highways. Oregon along with many...
This thesis explores the relationship between crime, transportation network connectivity, and engineered facilities built to increase walkability through a case study of twenty-five sites within the city of Spokane, Washington. Using data spanning between 2008 and 2010, the author developed a GIS model representing conditions of the built environment, social...
As the traffic demand increases at a faster rate than the upgrade and maintenance of
transportation facilities through the traditional public financing methods in the United
States, the Public-Private Partnership (PPP) is becoming an important supplement to
the public transportation infrastructure investment. There are already several existing
PPP toll road...
The present highway funding system, especially fuel taxes, may become less reliable revenue sources in the future, while the transportation public agencies do not have the sufficient financial resources needed to meet the increasing traffic demand. Regarding the socio-economic impact of road privatization, a wide range of approaches and models...
This dissertation explores algorithms for learning ranking functions to efficiently solve search problems, with application to automated planning. Specifically, we consider the frameworks of beam search, greedy search, and randomized search, which all aim to maintain tractability at the cost of not guaranteeing completeness nor optimality. Our learning objective for...
There are many different types of automatic data collection technologies that have been used in transportation system applications such as pneumatic tubes, radar, video cameras, inductive loops detectors, wireless toll tags, and global positioning systems (GPS). Nevertheless, there are still multiple examples of important and helpful transportation system data that...
Gap acceptance behavior is critical to the safety and operational performance of unsignalized intersections. The complex nature of the human behavior and its dependence on various socioeconomic and environmental parameters makes it challenging for transportation professionals to assess the performance of such intersections. To investigate the behavioral patterns of drivers...
The purpose of this dissertation was to explore the experiences of Asian group leaders who were leading groups in Asia. This research was developed to address a need for exploratory research in the area of Asian group leaders' perceptions and experiences during the process of leading groups in Asia. Grounded...
