  • Opportunities and challenges for decision support systems in log truck scheduling and dispatching

    Creator:
    Kokenge, Kyler S.
    Abstract:
    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...

  • Transportation network connectivity, facilities encouraging walkability, and crime

    Creator:
    Bornasal, Floraliza B.
    Abstract:
    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...

  • Estimating the impacts of a vehicle mileage fee using a discrete continuous choice modeling approach

    Creator:
    Valluri, Divya
    Abstract:
    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...

  • The review of PPP toll roads in the US and the simulation of the Chicago Skyway

    Creator:
    Xu, Wei
    Abstract:
    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...

  • Utilizing wireless-based data collection units for automated vehicle movement data collection

    Creator:
    Saeedi, Amirali
    Abstract:
    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...

  • Fuzzy logic for improved dilemma zone identification : a simulator study

    Creator:
    Moore, Derek
    Abstract:
    The Type-II dilemma zone refers to the segment of roadway approaching an intersection where drivers have difficulty deciding to stop or proceed through at the onset of the circular yellow (CY) indication. Signalized intersection safety can be improved when the dilemma zone is correctly identified and steps are taken to...

  • An evaluation of gap acceptance behavior at unsignalized intersections

    Creator:
    Nabaee, Sahar
    Abstract:
    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...

  • Learning ranking functions for efficient search

    Creator:
    Xu, Yuehua
    Abstract:
    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...

  • Optimal mixture of road network ownership

    Creator:
    Li, Mingxin
    Abstract:
    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...
