  • Energy and Air Quality Impacts of Truck Only Lanes A Case Study of Interstate 75 Between Macon and McDonough Georgia
    Energy and Air Quality Impacts of Truck Only Lanes: A Case Study of Interstate 75 Between Macon and McDonough, Georgia
    Kim, Daejin ;
    Guin, Angshuman
    2018-11-01 | PDF
    Because heavy-duty truck operations can significantly affect traffic congestion, especially on road grade, the creation of exclusive lanes for trucks has been viewed as a potential alternative to reduce congestion delay, fuel consumption, and emissions. However, few studies have rigorously evaluated the effectiveness of truck-only lanes in achievin ...
  • Scale in Housing Policy A Case Study of the Potential of Small Area Fair Market Rents
    Scale in Housing Policy: A Case Study of the Potential of Small Area Fair Market Rents
    Palm, Matthew
    2018-11-01 | PDF
    The U.S. Department of Housing and Urban Development (HUD) caps subsidies for Section 8 housing vouchers using limits known as the Fair Market Rents (FMRs). HUD recently implemented Small Area Fair Market Rents (SAFMRs), based on ZIP Codelevel rents, to improve options for voucher recipients in high-opportunity areas. I use a proprietary dataset of ...
  • Use of Biocementation for Slope Stabilization of Levees
    Use of Biocementation for Slope Stabilization of Levees
    Jiang, Xinyi ;
    Rutherford, Cassandra
    2018-11-01 | PDF
    While levee embankments are the first line of defense for urban flooding, recent flooding events have revealed widespread slope instability of embankments around the country that can lead to levee failures. This work aimed to improve the slope stability of earthen levees by strengthening the soil through the use of a biologically-inspired technique ...
  • Dynamic Scheduling of Chassis Movements With Chassis Processing Facilities in the Loop
    Dynamic Scheduling of Chassis Movements With Chassis Processing Facilities in the Loop
    Chassiakos, Anastasios ;
    Jula, Hossein
    2018-11-01 | PDF
    This work studies the optimization of scheduling of chassis and container movements at the operational level for individual trucking companies when Chassis Processing Facilities (CPFs) are available for use in the vicinity of a container port within a major metropolitan area. A multi-objective optimization problem is formulated in which the weighte ...
  • Development Training Education and Implementation of LowCost Sensing Technologies for Bridge Structural Health Monitoring SHM
    Development, Training, Education, and Implementation of Low-Cost Sensing Technologies for Bridge Structural Health Monitoring (SHM)
    Moreu, Fernando ;
    Lippitt, Christopher D.
    2018-11-01 | PDF
    Transportation infrastructure needs continuous monitoring. However, traditional inspections cost money and are conducted visually. New technologies for bridge monitoring are expensive and complex. This project involved developing cost-effective sensor technologies that can be applied towards the maintenance of railroad bridges by recording referenc ...
  • Application of a MultiAgent System with the LargeScale AgentBased Model for Freight Demand Modeling Research Brief
    Application of a Multi-Agent System with the Large-Scale Agent-Based Model for Freight Demand Modeling [Research Brief]
    Lee, EunSu ;
    Taleqani, Ali Rahim
    2018-11-01 | PDF
    In this study, researchers used the agent-based simulation (ABS) for modeling agricultural transportation demand. With the simulation model, geographic information systems (GIS) was utilized to collect and analyze remote sensing of agricultural crops. The researchers reviewed agent-based modeling in freight and public transportation planning to fil ...
  • Application of a MultiAgent System With the LargeScale AgentBased Model for Freight Demand Modeling
    Application of a Multi-Agent System With the Large-Scale Agent-Based Model for Freight Demand Modeling
    Lee, EunSu ;
    Rahim-Taleqani, Ali
    2018-11-01 | PDF
    To support agricultural logistics and energy development, road and bridge infrastructure has been in North Dakota due to the recent oil boom and the long-term importance of the agricultural industry. With the advance of simulation and data mining, the agent-based model (ABM) has emerged as a solution. Agent-based modeling techniques reflect a high ...
  • Experimental Evaluation of the Engineering Behavior of SoilBiochar Mixture as a Roadway Construction Material
    Experimental Evaluation of the Engineering Behavior of Soil-Biochar Mixture as a Roadway Construction Material
    Manahiloh, Kalehiwot Nega ;
    Lamprinakos, Renee
    2018-11-01 | PDF
    Past studies have investigated the influences of biochar addition on the nutrient removal and saturated conductivity properties of soils. Literature survey showed that there is a gap in the amount of work devoted to studying the effects of biochar addition on strength and volume change properties of soils. If biochar amended soils are to be used as ...
  • The Interrelationships between Speed Limits Geometry and Driver Behavior
    The Interrelationships between Speed Limits, Geometry, and Driver Behavior
    Savolainen, Peter T. ;
    Gates, Timothy J.
    2018-11-01 | PDF
    The relationship between speed and safety continues to be a high-priority research topic as numerous states consider speed limit increases. This study leveraged data from the Second Strategic Highway Research Program (SHRP2) Naturalistic Driving Study (NDS) to examine various aspects of driver behavior, including speed limit selection and engagemen ...
  • Improving the Durability of the Inverted TBeam Bridge System
    Improving the Durability of the Inverted T-Beam Bridge System
    Roberts-Wollmann, Carin L. ;
    Pulumati, Vijaykanth
    2018-11-01 | PDF
    The inverted T‐beam system provides an accelerated bridge construction alternative. The system consists of adjacent precast inverted T‐beams finished with a cast‐in‐place concrete topping. The system offers enhanced performance against reflective cracking and reduces the likelihood of cracking due to time dependent effects. Differential shrinkage i ...
  • Older Adults Attitudes and Opinions about Automated Vehicles A Literature Review
    Older Adults’ Attitudes and Opinions about Automated Vehicles: A Literature Review
    Eby, David W ;
    Molnar, Lisa J
    2018-11-01 | PDF
    The maintenance of mobility and independence among older adults are frequently cited benefits of developing automated driving technologies. This paper reviews the empirical literature on older adults’ attitudes and opinions regarding partial to fully automated vehicles. The findings of 10 studies are reviewed. Overall, the attitudes and opinions of ...
