The International Council on Clean Transportation has released a report that examines the use of remote sensing in regulating and controlling pollution from on-road vehicles. Remote sensing systems use absorption spectroscopy to non-intrusively measure pollutant concentrations in the exhaust plumes of in-use vehicles. This report identifies how remote sensing compares to the portable emissions ...

The Upper Great Plains Institute at North Dakota State University has released a report that reviews agent-based models of transportation. These models use data mining and simulation to reflect a high level of detail for travel patterns in a region or state. This report also determines an agent’s travel behavior in rural and small urban freight movement, designs a multi-agent system, and invest...

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 528: Analyzing Data for Measuring Transportation Performance by State DOTs and MPOs summarizes what data state departments of transportation (DOTs) and metropolitan planning organizations (MPOs) are using and how they are measuring transportation performance. Knowledge about transportation data already exists, but may be...

TRB’s National Cooperative Highway Research Program (NCHRP) Research Report 891: Dedicating Lanes for Priority or Exclusive Use by Connected and Automated Vehicles identifies and evaluates opportunities, constraints, and guiding principles for implementing dedicated lanes for connected and automated vehicles. This report describes conditions amenable to dedicating lanes for users of these vehic...

TRB has released Critical Issues in Transportation 2019 . In this report, which is updated periodically by the TRB Executive Committee, a series of challenging questions are posed to explore issues and opportunities that may arise 10 to 20 years into the future. These questions, 63 in all, have been organized into 12 topic areas and provide a way to frame future areas of research, policy analys...

TRB's E-Circular 238: 2018 National Household Travel Survey Workshop explored users' experiences with the 2017 National Household Travel Survey (NHTS) dataset at an August 2018 workshop in Washington, D.C. Conducted by the Federal Highway Administration (FHWA), the NHTS is the authoritative source on the travel behavior of the American public. It is the only source of national data that allows ...

The Center for Transportation Studies at the University of Minnesota has released a report that determines whether some of the limitations of Bridge Weigh-in-Motion (BWIM) systems may be overcome by enriching their datasets. These limitations include poor accuracy with multiple vehicle passage, and inability to accurately capture the passage of a vehicle moving at variable speeds. BWIM systems ...

The Iowa Department of Transportation has released a report that explores potential applications of expanded maintenance data and traffic data. This report focuses on using automated vehicle location and snowplow image capture technologies to examine winter weather events and their effects on crashes. These data resources have the potential to supplement existing efforts to monitor traffic, wea...

The U.S. Congressional Research Service has released a report that summarizes the newest version of the Geospatial Data Act (GDA). The GDA seeks to organize and manage geospatial data among federal agencies, local and state authorities, the private sector, and academia. The GDA has the potential to illuminate how each responsible agency budgets for its geospatial activities, which may allow Con...

The Institute of Transportation Studies at the University of California at Davis has released a report that establishes a framework for long-distance data collection that redefines long-distance travel. Current travel demand models have not traditionally focused on long-distance travel patterns. The goal of this report is to update the existing planning framework to include long-distance travel...
