The Upper Great Plains Institute at North Dakota State University has released a report that investigates the differences in prestress losses and temperature gradients in a concrete deck bulb tee girder bridge. This report also monitors the prestress loss effects from the friction in the casting bed.

The National Center for Asphalt Technology at Auburn University has released a report that identifies current methods that state departments of transportation (DOTs) use to determine initial service life for use in life cycle cost analysis (LCCA) for both asphalt and concrete pavements. This report also determines actual service life of these pavements. State DOTs use LCCA to choose the most cost-effective project alternatives when planning new construction or reconstruction of their roadways.

The Institute for Transportation at Iowa State University has released a report that investigates the use of surveillance cameras as a sensor for traffic state estimation. Most of the cameras installed on freeways and arterials are still used for manual surveillance purposes only.

The Institute for Transportation at Iowa State University has released a report that develops visualization techniques and methods of pavement performance data in a communication-friendly format. For the purposes of this report, end users were thought to be either county office administrators examining the status of the roads in their counties and the state, or engineers working with the data sets. This report develops visualizations for both user groups.

The National Center for Asphalt Technology (NCAT) at Auburn University has released a report that summarizes key findings from the previous cycles and documents the experiments, analyses, and findings from the fifth cycle of the NCAT test track. Highway agencies and industry sponsors utilize the NCAT test track to evaluate specific research needs and identify broader research needs of the asphalt pavement community

The Institute for Transportation at Iowa State University has released a report that develops visualizations for displaying pavement performance data and information. This report focuses on identifying information about the different types of cracks, relationships between them, relationships between condition and distress data, and performance in Iowa districts and counties.

The Mineta Transportation Institute at San Jose State University has released a report that analyzes the immediate economic impacts of the first high-speed rail project in California’s central valley. This report focuses on the effect this construction project has had on employment and spending throughout the central valley and the rest of the state.

The University of Texas at Austin has released a report that demonstrates a variety of smart-transport technologies, policies, and practices for highways using connected autonomous vehicles, roadside equipment, and related technologies. The goal of this report is to maximize the benefit of these technologies in terms of improved driver safety, reduced congestion, and agency cost savings.

The Mineta Transportation Institute at San Jose State University has released a report that examines documented attempts to derail trains and attack rail infrastructure in order to discern overall patterns and trends. This report also identifies differences in attackers’ motives, objectives, and modes of operating.

The Institute for Transportation at Iowa State University has released a report that analyzes the circumstances that increase the probability of severity in large-truck crashes. This report identifies the different ways severity of crashes occur based on drivers’ gender.
