    What Do Americans Think About Federal Tax Options to Support Transportation? Results from Year Ten of a National Survey [Brief]
    Agrawal, Asha Weinstein ;
    Nixon, Hilary
    2019-06-01 | What Do Americans Think About Federal Tax Options to Support Transportation? | PDF
    This research brief summarizes results from the tenth year of an annual survey project exploring national support for raising federal transportation revenues through gas taxes or mileage fees.
  • Exploring Unintended Environmental and Social Equity Consequences of TransitOriented Development Policy Brief
    Exploring Unintended Environmental and Social Equity Consequences of Transit-Oriented Development [Policy Brief]
    Rodier, Caroline ;
    Alemi, Farzad
    2019-06-01 | PDF
    Coordinated land use and transportation plans that locate high-density, mixed-use development near high-quality rail and bus transit are essential in helping communities reach important goals, such as economic development, reduced traffic congestion, greater transportation choices, and improved public health. These plans may also be critical to mee ...

    What Do Americans Think About Federal Tax Options to Support Transportation? Results from Year Ten of a National Survey
    Agrawal, Asha Weinstein ;
    Nixon, Hilary
    2019-06-01 | What Do Americans Think About Federal Tax Options to Support Transportation? | PDF
    This report summarizes the results from the tenth year of a national public opinion survey asking U.S. adults questions related to their views on federal transportation taxes. A nationally representative sample of 2,723 respondents completed the online survey. The questions test public opinions about both raising the federal gas tax rate and replac ...
  • Identifying HighRisk Intersections for Walking and Bicycling Using Multiple Data Sources in the City of San Diego
    Identifying High-Risk Intersections for Walking and Bicycling Using Multiple Data Sources in the City of San Diego
    Hasani, Mahdie ;
    Jahangiri, Arash
    2019-06-01 | PDF
    Over the last decade, demand for active transportation modes such as walking and bicycling has increased. While it is desirable to provide high levels of safety for these eco-friendly modes of travel, unfortunately, the overall percentage of pedestrian and bicycle fatalities increased from 13% to 18% of total road-related fatalities in the last dec ...
  • Development of FineGrained Spatial Resolution for an Integrated Health Impacts Assessment Tool for the Sacramento Region
    Development of Fine-Grained Spatial Resolution for an Integrated Health Impacts Assessment Tool for the Sacramento Region
    Rowangould, Dana L ;
    Karner, Alex A.
    2019-06-01 | PDF
    Understanding the public health impacts of transportation plans can inform decision making and project prioritization. Because each plan and regional context is different, there is a need for site-specific methods to assess the extent and distribution of health impacts of changes to a region’s transportation system. To fill this need, researchers h ...
  • Development of Performance Matrices for Evaluating Innovative Intersections and Interchanges Research Brief
    Development of Performance Matrices for Evaluating Innovative Intersections and Interchanges [Research Brief]
    Zlatkovic, Milan ;
    Corrigan, Margaret
    2019-06-01 | PDF
    Complete benefits and impacts of innovative intersection and interchange designs are still unclear. There is a lack of methodologies for a quick estimation of these designs for various transportation modes (vehicular traffic, transit, bicyclists and pedestrians), as well as the access management. This study aims to answers those questions. The stud ...
  • Quantifying Traffic CongestionInduced Change of NearRoad Air Pollutant Concentration
    Quantifying Traffic Congestion‐Induced Change of Near‐Road Air Pollutant Concentration
    Luo, Ji ;
    Moretti, Ayla
    2019-06-01 | PDF
    The objective of this study was to examine the relationship between air quality and traffic and weather parameters. With air quality measurements spanning over 11 months, the authors attempted to gain better understanding of the near-freeway air pollutant concentration, traffic speed, traffic flow, and weather parameters. The authors applied both m ...
  • Experimental Investigation of Longitudinal Closure Joint Using 90 Hooked Bars in Accelerated Bridge Construction
    Experimental Investigation of Longitudinal Closure Joint Using 90° Hooked Bars in Accelerated Bridge Construction
    Jahromi, Azadeh Jaberi ;
    Azizinamini, Atorod
    2019-06-01 | PDF
    Several alternatives are used to connect prefabricated bridge deck elements using closure joints but cost and construction considerations limit their use in field applications. In this research, a new detail is proposed to efficiently connect these elements in closure joints. The new detail consists of 90° hooked reinforcement and normal strength c ...
  • Prestress Losses and Development of ShortTerm Data Acquisition System for Bridge Monitoring Research Brief
    Prestress Losses and Development of Short-Term Data Acquisition System for Bridge Monitoring [Research Brief]
    Barr, Paul J. ;
    Pace, Justin M
    2019-06-01 | PDF
    For example, for prestressed, precast concrete girder bridges, an accurate estimation of the prestress force is needed for proper design. However, obtaining information on the behavior of in-place bridges can be challenging. Researchers used a short-term data acquisition system to obtain bridge behavior data under live loads. They also used embedde ...
  • Guide for the Selection of Rapid Repair Systems for EarthquakeDamaged Reinforced Concrete Bridge Columns
    Guide for the Selection of Rapid Repair Systems for Earthquake-Damaged Reinforced Concrete Bridge Columns
    Sneed, Lesley H. ;
    Fraioli, Giacomo
    2019-06-01 | PDF
    This guide addresses the selection of systems for rapidly repairing earthquake-damaged reinforced concrete bridge columns with different types and levels of damage. Recent studies in the technical literature on repair have demonstrated that different techniques can be a viable option for restoring the use of earthquake-damaged RC bridge columns, ev ...
  • Toward Computational Simulations of Behavior During Automated Driving Takeovers A Review of the Empirical and Modeling Literatures
    Toward Computational Simulations of Behavior During Automated Driving Takeovers: A Review of the Empirical and Modeling Literatures
    McDonald, Anthony D ;
    Alambeigi, Hananeh
    2019-06-01 | PDF
    Objective: This article provides a review of empirical studies of automated vehicle takeovers and driver modeling to identify influential factors and their impacts on takeover performance and suggest driver models that can capture them.
