  • 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...

  • 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...

  • 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...

  • 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...

  • Perceived Effectiveness of Highway Work Zone Intrusion Mitigation Technologies: A State DOT Perspective

    Creator:
    Kadalli, Manjunath Veeresh
    Abstract:
    Highway work zones are extremely dangerous environments due to the presence of workers near high-speed traveling vehicles. This dynamic environment results in a disproportionate number of accidents that cause injury and casualty to both drivers and workers due primarily to vehicular intrusions into work zones. Several emerging work zone intrusion...

  • 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...

  • 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...

    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...

  • Multi-hazard framework and analysis of soil-bridge systems : long duration earthquake and tsunami loading

    Creator:
    Carey, Trevor J.
    Abstract:
    During the 2011 Great East Japan Earthquake and Tsunami, numerous bridge structures were damage or destroyed. The damage to bridge systems was caused by long duration strong ground shaking, tsunami inundation forces, or both. Long duration strong ground shaking from subduction zone earthquakes and the multi-hazard scenario of combined earthquake...
