Culvert inspection is a key enabler that allows Minnesota Department of Transportation (MnDOT) to manage the state’s highway culvert system. When quantitative detail on culvert condition is required, an inspector will need to use enhanced inspection technologies. Enhanced inspection technologies such as; laser ring profiling, sonar, inclinometer, mandrel...

Variable speed limit (VSL) systems utilize information on traffic speed, occupancy, and volume detection, weather, and road surface conditions to determine the appropriate speeds at which drivers should be traveling, given current roadway and traffic conditions. The use of VSL during less than ideal conditions, such as traffic and weather conditions, can...

This report investigates how the geometric design components of a roundabout may contribute to bicycle crashes. An Australian and New Zealand crash analysis found that most of the crashes occurred at urban local road roundabouts, in 50 km/h speed limit zones. The crashes predominantly occurred on the circulating lane near the entry for an approach road and...

Australian and New Zealand road agencies and operators are preparing for the introduction of Automated Vehicles (AVs). 'This report investigates the potential changes needed to the way road networks are managed to consistently support and optimise the outcomes from the introduction of AVs. The project reviewed international and local documents and...

On August 1, 2007, the I–35W Mississippi River Bridge (I–35W Bridge) in Minneapolis, MN, collapsed. The National Transportation Safety Board (NTSB) turned to the Federal Highway Administration (FHWA) to provide technical expertise during their investigation. In response, NTSB issued recommendations to FHWA and the American Association of State...

This report describes an investigation of analytical, Highway Capacity Manual (HCM)-compatible evaluation methods for urban street active transportation and demand management (ATDM). ATDM strategies have been successfully deployed in the United States, but the lack of available analytical methods may be reducing their successful adoption by more cities. To...

Automated vehicle (AV) technology has the potential to completely change how we travel, how we ship goods, and on a larger scale, how we think about mobility. While fully automated vehicles are not yet commercially available, the technology is developing rapidly and some robotic driving functions are already on public roads today. Nevertheless, the challenges...
