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...

In supporting State Departments of Transportation (DOTs) and metropolitan planning organizations (MPOs) in using Geographic Information Systems, the Federal Highway Administration (FHWA) is publishing this Case Study Report focusing on the use of online, geospatial dashboards by transportation agencies to analyze and display operational metrics and performance...

Driving intelligence tests are critical to the development and deployment of autonomous vehicles. The prevailing approach tests autonomous vehicles in life-like simulations of the naturalistic driving environment. However, due to the high dimensionality of the environment and the rareness of safety-critical events, hundreds of millions of miles would be...

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...
