This report provides recommendations for integrating both nondestructive evaluation (NDE) data and field data from structural health monitoring (SHM) to obtain load ratings that reliably represent a bridge's load-carrying performance. Modern NDE techniques, which provide accurate location and characterization of deteriorations, enable more reliable...

Many Minnesota bridges have older barriers or parapets that met the design code at the time of construction in the 1950s. Many of these bridge barriers no longer meet current strength and performance requirements of NCHRP Report 350 or the Manual for Assessing Safety Hardware (MASH). As the Minnesota Department of Transportation (MnDOT) begins to rehabilitate...

Urban travel patterns are affected by many factors including changes in demography, land use, economics, technology, and mobility options. Public transportation must evolve to remain responsive. The TRB Transit Cooperative Research Program's TCRP Research Report 221: Redesigning Transit Networks for the New Mobility Future presents case studies and...

In 2020, the novel coronavirus pandemic (COVID-19) enveloped the world, leading to a public health crisis that profoundly changed all aspects of society, including transportation. With public transit and shared mobility at a critical juncture, the University of California’s Institute of Transportation Studies (UC ITS) and the Transportation Research Board...

asPECT provides a methodology to calculate the life cycle greenhouse gas emissions or ‘carbon footprint’ of asphalt used in highways.  The tool and supporting docuemntation is available from the UK Transportation Research Laboratory (TRL) web site at https://trl.co.uk/permanent-landing-pages/asphalt-pavement-embodied-carbon-tool-aspect/...

Automated driving systems (ADS) have the potential to fundamentally change transportation, and a growing number of these systems have entered the market and are currently in use on public roadways. However, drivers may not use ADS as intended due to misunderstandings about system capabilities and limitations. Moreover, the real-world use and effects of this...

Compaction is one of the most important factors that affects the durability of asphalt pavements. Many studies have been focused on developing methods to improve compaction. Previously, the authors found that the addition of small percentages of Graphite Nanoplatelets (GNPs) significantly increase the compactability of asphalt mixture. Traditional viscosity...

The main goal of this project was to identify focus crash and facility types (FCFTs) and associated contributing factors to better inform applications of systemic safety improvements. The selection of FCFTs was guided by the use of the Fatality Analysis Reporting System and the Highway Safety Information System (HSIS) databases (NHTSA 2018a; FHWA 2018c). The...

This document serves as a quick reference guide for transportation professionals in State and local agencies that are interested in applying a systemic approach to road-safety management. This guide provides brief overviews of the systemic approach, common target crash types and their associated facility types, and contributing factors. It also provides a six-...

The transportation-engineering community is transforming by integrating quantitative methods into the task development process. This report identifies opportunities to better understand the relationships between road safety and factors that affect traffic-crash occurrence and severity. In this report, current statistical-analysis methods and data sources used...

This project established protocols to help evaluate the utilization of chemical stabilization methods to potentially improve the engineering behavior of problematic soils with and without soluble sulfates within the state of Montana. In addition, construction life cycle cost analyses were used to compare existing approaches used by MDT versus chemical...

Nineteen state highway locations around south-central and southwestern Minnesota were evaluated during winter 2019-20 for the application of deicer “hot shots,” extra levels of salt or other chemical treatments used to deice roadways and maintain roadway driving levels of performance. Locations were selected based on previous recordkeeping that...
