The movement of superheavy loads (SHLs) has become more common over the years, since it is a vital necessity for many important industries, such as chemical, oil, electrical, and defense. SHL hauling units are much larger in size and weight compared to the standard trucks. SHL gross vehicle weights may be in excess of a few million pounds, so they

Transportation agencies face growing demand for an integrated transportation network that safely and efficiently moves people. Motorists, freight, transit passengers, bicyclists, and pedestrians, including individuals with disabilities, have unique needs, and infrastructure is being adapted to the multimodal nature of travel. The project developmen

The AASHTO LRFD Bridge Design Specifications do not explicitly include a quantifiable fracture limit state. Fracture control in steel bridges is currently based on mitigating potential fracture initiators through proper structural detailing and specifying minimum impact toughness for base material. This fracture control approach has been successful

The objective of the study was to evaluate the safety effects of two countermeasures with respect to vehicle–pedestrian crashes—the provision of protected or protected/permissive left-turn phasing and the provision of leading pedestrian intervals (LPIs)—using a before–after empirical Bayesian methodology. The study used data from North American cit

On a monthly basis, each State is required to report to the Federal Highway Administration (FHWA), the amount of gallons taxed by that state. This data is analyzed and compiled by FHWA staff. The data on the amount of on-highway fuel use for each State is then used to attribute federal revenue to each State. Yearly, the FHWA, Office of Policy, prov

You did it! You recognized that speeding is a significant safety problem in your jurisdiction, and you put a lot of time and effort into developing a Speed Management Action Plan that holds great promise for reducing speeding-related crashes and fatalities. So…what’s next?
Automated vehicles have the potential to significantly transform the nation’s roadways. They offer potential safety benefits, but also introduce uncertainty for agencies responsible for the planning, design, construction, operation, and maintenance of the roadway infrastructure. The Federal Highway Administration (FHWA) is initiating a national con

Intelligent Transportation Systems (ITS) present an array of promising ways to improve motorcycle safety. While ITS technologies have predominantly targeted automobiles and commercial vehicles, little has been done to specifically address motorcycles or motorcycle safety. To help rectify this, this project surveyed a wide range of ITS technologies
