  • Direct Shear Interface Friction and Linear Motion Shaking Response of Ecoroofs

    Creator:
    Kilroy, Kimberly A.
    Abstract:
    Ecoroofs have become more prominent in recent years. However, there is currently no enforceable standard or building code for the design and construction of ecoroofs across the United States (Kraupa, 2014). Further research is needed to determine how ecoroofs respond to roof motion and to develop an appropriate design standard.The...

  • Examining the Impacts of the COVID-19 Pandemic on Driver Behavior and Injury Severity: Econometric Methods and Applications

    Creator:
    Ghosh, Sukallyan
    Abstract:
    The onset of the COVID-19 pandemic led to significant transformations in global mobility patterns, primarily driven by stay-at-home orders and economic shutdowns. These measures resulted in a substantial decline in travel activities worldwide. In the United States, there was a notable reduction in travel demand, with a corresponding decrease in...

  • Durability and Performance of High Early Strength Concrete for Structural Bridge Deck Overlays

    Creator:
    Smith, Jeremy A.
    Abstract:
    High early strength concrete (HESC) allows for faster construction with less impact on traffic, thus reducing the indirect costs associated with a project. There are multiple methods for achieving early strength, such as alternative cements like calcium sulfoaluminate (CSA) or chemically accelerated portland cements. The standard criteria for an HESC...

    Creator:
    Claveria, Joseph B.
    Abstract:
    Distracted driving is an adverse driving behavior that is widely known to impair the safety of all roadway users and traffic flow. Despite the extensive research efforts on the prevalence and effects of distracted driving on roadway safety and performance, the number of vehicular crashes and fatalities resulting from distracted...

  • The Statistical and Econometric Analyses of the Impacts of Covid-19 on Truck Driver Behavior

    Creator:
    Velasquez, Brianna N.
    Abstract:
    The outbreak of the Coronavirus Disease 2019 (COVID-19) and the restrictions implemented in response to it (e.g., stay-at-home orders, social distancing mandates, business closures) had unprecedented effects on the trucking industry. The pandemic prompted the first significant overhaul of federal hours-of-service (HOS) regulations in over 15 years. Prior to the...

  • Modeling Unobserved Heterogeneity and the Injury Severities of Truck Drivers in Run-Off-Road (ROR) Crashes: Econometric Methods and Applications

    Creator:
    Al-Bdairi, Nabeel Saleem Saad
    Abstract:
    Recent statistics regarding large truck crashes reveal that fatality rates of large trucks per 100 million vehicle miles traveled (VMT) and fatality rates per 1,000 registered vehicles are higher than those for passenger vehicles. These statistics underscore the need for greater efforts by safety professionals to help mitigate the impacts...

  • Mitigating Wildfire Impacts on Mobility Using GIS, Fire Modeling, and Operations Simulation

    Creator:
    Al-Hamadani, Saifaldawlah
    Abstract:
    Wildfires are a recurring disaster that threatens communities living close to forests and result in significant financial losses along with negative environmental effects, especially with the increase of wildfire season length and intensity due to climate change and increasing urbanization. Wildfire events can also have a significant impact on the...

  • Automated Monitoring of Modular Construction Factories using Computer Vision

    Creator:
    Panahi, Roshan
    Abstract:
    Modular construction is increasingly seen as an efficient construction method in terms of time, cost, and energy. The full realization of these advantages partly relies on the efficiency of the production process inside the modular factories, which currently rely on tedious manual monitoring methods or expensive automated techniques. As a...

  • Removing Residual Lane Markings to Reduce Driver Confusion

    Creator:
    Weber, Jane B.
    Abstract:
    When pavement markings on roadways are removed, scarring can occur leaving behind traces of where the marking used to be called ghost lines. These ghost lines can confuse drivers on the roadway and divert their attention from the correct lane markings leading them into the false lane. Previous research has...

  • The Number of Lanes and Crash Injury Severities of Commercial Motor Vehicle Drivers: Advanced Econometric Models and Applications

    Creator:
    Kim, Jaekook
    Abstract:
    Considering the deadly impacts of commercial motor vehicle (CMV) crashes on road safety, many previous studies have put in efforts to find the determinants of CMV crash injury severities. However, studies examining the impact of the different number of lanes on CMV crash injury severities are lacking. Besides, the importance...
