In March 2010, the U.S. Department of Transportation (DOT) released a policy statement supporting the development of fully integrated transportation networks. The policy is to “incorporate safe and convenient walking and bicycle facilities into transportation projects.” The TRB National Cooperative Highway Research Program's NCHRP Synthesis...

Despite recent developments, the measurement of actual pavement surface deflections under the axles of a moving truck at a network level remains a challenge in pavement engineering. Several pieces of equipment have been developed in the past decade but they fail to accurately measure actual deflection. Most of them measure indicators of deflection or deflection...

Urban road performance metrics, indicators and benchmarks describe how our road assets (and transport systems) are functioning and operating. Indicators in particular are useful to understand how well our road assets are performing within the context of the road users’ (and societal) expectations. This enables agencies and authorities to manage investment...

Over the past 10 to 15 yr, the use of high-friction surface treatments (HFSTs) as a safety countermeasure has grown exponentially. HFSTs are pavement-surface treatments that restore or enhance pavement friction at locations with high friction demand, such as curves, ramps, and intersection approaches. While the crash-reduction benefits of HFSTs have been...

The procedures detailed in the 6th Edition of the Highway Capacity Manual (HCM) estimate capacity and several operational measures, including those determining Level of Service, for freeway facilities as well as surface streets. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 290: Highway Capacity Manual Methodologies...

In-person enforcement is the most common form of speed enforcement in the United States. It has several limitations; law enforcement officers are able to stop only a small proportion of speeders. Road design and traffic conditions can make roadside stops difficult, and stops can be dangerous for both the driver and the law enforcement officer, who are at risk...

The amount of data surrounding the application of emerging technologies is expanding, producing “big data” at magnitudes not previously seen. While a few agencies have found some success with individual projects, most are uncertain on how to handle this level of big data at an organizational level. The TRB National Cooperative Highway Research...

With increased connectivity between vehicles, sensors, systems, shared-use transportation, and mobile devices, unexpected and unparalleled amounts of data are being added to the transportation domain at a rapid rate, and these data are too large, too varied in nature, and will change too quickly to be handled by the traditional database management systems of...

In 2019, the Virginia Transportation Research Council (VTRC) published Improving the Identification and Characterization of Arterial Congestion Bottlenecks by Zhao and Venkatanarayana.  The report described a study recommending that the Virginia Department of Transportation and the Office of Intermodal Planning and Investment pursue development of data...

Vehicular traffic contributes a large fraction of the pollutant load in stormwater runoff from roadways. While runoff concentrations have historically been characterized for urban roads with high average daily traffic (ADT), the runoff quality from paved rural roads that have relatively low ADT is largely unknown. In this study, runoff from low-volume roads (...

The long-term goal of this research is to provide results that inform decisions about technologies and public policies for smart cities and connected vehicles.  In this year, under Project 274, we made particular progress on spectrum management issues, on policy processes, and in assessing the impact of wireless technologies on performance of wireless...

Since Kentucky’s initial rumble strip designs were adopted, there has been additional research and experimentation in other states with alternative designs as a response to complaints from the public about noise pollution caused by rumble strips. The new research indicates that other rumble strip designs might provide increased interior noise/vibration...
