Blockchain and other distributed ledger technologies (DLTs) could help create trust and consensus in areas of the transport sector where they are needed for efficient solutions but currently often lacking. Such challenges concern for instance clearing transactions amongst multiple parties with divergent interests, authenticating provenance, managing assets, and...

Incorporating cracking tests and criteria in binder acceptance, mix design, and construction quality control (QC and quality assurance (QA) offer a way to improve pavement performance. The objective of this research is to identify and, if necessary, refine binder and mixture tests capable of addressing asphalt cracking in Minnesota asphalt pavements. The tests/...

Interstate widening projects are commonplace in Kentucky, and safety is of primary concern within the project work zone. Past experience with long work zones revealed two critical safety issues: driver confusion due to unclear pavement markings and a lack of continuous work zone signage for motorists indicating they are still within a work zone. This concern is...

This report presents a wave method to be used for the structural identification and damage detection of structural components in bridges, e.g., bridge piers. This method has proven to be promising when applied to real structures and large amplitude responses in buildings (e.g., mid-rise and high-rise buildings). This study is the first application of the method...

This report summarizes the results of a one-year project aimed at exploiting vehicle-to-infrastructure (V2I) communication to enhance the effectiveness of real-time adaptive traffic signal control systems. As originally formulated, the project’s goal was to explore the potential of using the sensing capabilities of connected autonomous vehicles (CAVs) to...

While seal coating has been widely used as a cost-effective strategy in asphalt pavement preservation by MnDOT and local agencies with great success, some cities and counties in Minnesota have reported their concerns about the premature stripping of street pavements that have been seal coated. The objective of this study was to diagnosis whether seal coating...

This report summarizes the key findings and lessons learned from the series of field, laboratory, and advanced numerical studies performed under Federal Highway Administration (FHWA) Transportation Pooled Fund Study TPF-5(183). This research program was established by the partnering state departments of transportation (DOTs) to identify opportunities to...

This report focuses on how cities can use climate action plans (CAPs) to ensure that on-demand mobility and autonomous vehicles (AVs) help reduce, rather than increase, green-house gas (GHG) emissions and inequitable impacts from the transportation system. We employed a three-pronged research strategy involving: (1) an analysis of the current literature on on-...

Washington State Department of Transportation (WSDOT) desired to evaluate F-shape and single slope concrete barriers wit h 6-inch tall drainage scuppers for compliance with American Association of State Highway and Transportation Official’s (AASHTO) Manual for Assessing Safety Hardware (MASH) evaluation criteria. The F-shape was a temporary concrete...

Motorcycle crashes make up a disproportionately high number of crashes on the Nation's roadways. Warning signs have the potential to reduce motorcycle crashes by drawing the attention of road users to situations that may be particularly hazardous for motorcyclists. The current study examined the potential for novel signs to be used as motorcycle-crash...

The development of automated trucking technology is progressing rapidly, and increasing numbers of on-road pilots suggest that full-scale commercial deployment of partially automated truck platoons on public roads is forthcoming.(1) In the United States, platoons typically consist of two to four trucks equipped with cooperative adaptive cruise control (CACC) to...

Alternative Intersections and Interchanges (A.I.I.s) are designs that improve operations and safety for motorized traffic by strategically adjusting the geometric features at a given location, working on the general principle of redistributing motor vehicle demand at an intersection in an attempt to limit the need to add capacity with new lanes to improve...
