  • Evaluation Tools for LowSpeed Automated Vehicle LSAV Transit Readiness of the Area
    Evaluation Tools for Low-Speed Automated Vehicle (LSAV) Transit Readiness of the Area
    Hong, Yubin ;
    Klauer, Sheila G
    2022-11-22 | PDF
    Automated shuttles are small, low-speed (generally less than 25 mph) vehicles that do not require a human operator, though to date all have included an onboard human attendant. This project aims to assess the limitations that the EasyMile EZ10 Gen 3 low-speed automated vehicle (LSAV) encountered while operating on public roadways. The primary inter ...
  • Unmanned Aerial Vehicles for Inspection of Tack Coats and Ancillary Highway Structures
    Unmanned Aerial Vehicles for Inspection of Tack Coats and Ancillary Highway Structures
    Dai, Fei ;
    da Silva, Aida
    2022-11-20 | PDF
    Unmanned aerial vehicles (UAVs), also known as drones, have emerged as a non-destructive sensing technology in the construction industry for many inspection practices. Compared to other non-destructive inspection technologies, using UAVs offers benefits ranging from accelerating data collection to accessing hard-to-read surfaces and locations. With ...
  • Monitoring of Illegal Removal of Road Barricades Using Intelligent Transportation Systems in Connected and NonConnected Environments
    Monitoring of Illegal Removal of Road Barricades Using Intelligent Transportation Systems in Connected and Non-Connected Environments
    Ngeni, Frank C ;
    Mwakalonge, Judith L
    2022-11-18 | PDF
    Illegal removal of road barricades without notice of road emergency officials and road users has resulted in fatalities, injuries, and property damages. It is only after an incident has occurred or someone noticed the removal and alerted the authorities for the barricade to be placed back at its intended location. Due to this event, traditional bar ...

    Developing a Safety Management System Including Hazardous Materials for Highway-Rail Grade Crossings in Region VII
    Zhao, Li ;
    Khattak, Aemal
    2022-11-15 | PDF
    Highway-rail grade crossings (HRGCs) rank among the leading locations for fatal crashes on the railroad network in the United States, and safety at HRGCs is a top priority for the railroads and the Federal Railroad Administration (FRA). This project studied HRGC safety needs by investigating crash data and HRGC inventory characteristics, and then d ...
  • Future of Work Scenario Planning for COVID19 Recovery
    Future of Work: Scenario Planning for COVID-19 Recovery
    Pan, Alexandra ;
    Shaheen, Susan
    2022-11-15 | PDF
    The COVID-19 pandemic caused widespread lockdowns across the world in early 2020, with major implications to spatial and temporal commuting patterns as a result of increased work from home (also known as telework) activities. There has been a high degree of uncertainty on what work from home impacts will persist in the future. In this report, we fi ...
  • Pilot Study: Machine Learning and Deep Learning Study for Fluid Structure Interaction Problems [Supporting Dataset]
    Simpson, Barbara G ;
    Scott, Michael H.
    2022-11-10 | ZIP
    Coastal bridges are critical to emergency response after extreme events and are vulnerable to cascading seismic-tsunami events. After the 2011 earthquake and subsequent tsunami in Japan, instances of damage and collapse were observed in Japanese bridges that survived the earthquake but failed under the hydrodynamic loads induced by the tsunami. The ...

    Steiner, Ruth
    2022-11-08 | PDF
    This project gains on-the-ground insight into competition for curb space, what issues drivers face, and the circumstances that inform their parking choices and related behaviors. To do so, it uses data from Reddit to examine US parcel delivery driver perceptions and behavior. The study uses “flexible” coding to analyze the collected comments, provi ...
  • Predicting Wildfire Impacts on Mobility Using GIS and Fire Simulation
    Predicting Wildfire Impacts on Mobility Using GIS and Fire Simulation
