Speeding-related crashes continue to be a serious problem in the United States and attempts to address this problem through a variety of approaches have not led to a substantial reduction in speed-related fatalities. A better understanding of speeding behavior is needed to inform the development of new speeding countermeasures. To address this issue,...

Researchers at the University of Nevada, Reno explored the feasibility of a self-sensing adaptive bridge bearing system. In this system, rubber bearings and sensors made of a magnetorheological elastomer (MRE) (or controllable rubber) respond to loads and vibrations through automated changes in stiffness. The system has a wireless, self-sensing capability that...

The objective of this research was to examine the link between driving speed and crash experience on roadway segments, taking into account roadway characteristics that influence speed and crash frequency and severity. A potential outcome of the research was improved safety performance functions that included a speed term or crash modification factors (CMFs)...

Corrosion of prestressed concrete reinforcement in bridge components is a major concern for state transportation agencies. The severity of the problem is amplified by the fact that the corrosion-induced damage in concrete reinforcement often does not show up on the surface until significant propagation has occurred. Moreover, prestressed reinforcement can...

This study combined multiple approaches to evaluate the structural and economic impact of using new-generation wide-base tires (NG-WBT) in New Brunswick, Canada. A three-dimensional finite-element model of a typical pavement structure was used to predict critical pavement responses. The model included measured tire-pavement contact forces among other variables...

This handbook presents a methodology that will aid highway asset owners and maintenance personnel with determining what assets, beyond pavements and bridges, are most important to support their agencies' missions and goals. The methodology prioritizes asset classes and identifies data related to those assets that best support a performance-based approach to...

The Virginia Department of Transportation (VDOT) has purchased a subscription to the StreetLight (SL) Data products that mainly offer origin-destination (OD) related metrics through crowdsourcing data. Users can manipulate a data source like this to quickly estimate origin-destination trip tables. Nonetheless, the SL metrics heavily rely on the data points...

Our project was based on the need to water new roadside installations more efficiently to ensure that the turfgrasses, especially the new salt-tolerant mixes, establish more successfully with a predictable and uniform amount of water during the establishment period. The first objective of this project was to do a preliminary investigation of alternative means...

The Federal Highway Administration mandates that all [bridge] structures in its inventory are to be inspected every two years. Consequently, deck surveys are conducted to identify unseen damage within them. A significant number of bridges in Virginia have concrete decks with an overlay. Methods commonly deployed on these decks, are limited in the quantitative...

This paper performs an ex-post cost–benefit and distribution analysis of the Gothenburg congestion charges introduced in 2013, based on observed effects and an ex-post evaluated transport model. Although Gothenburg is a small city with congestion limited to the highway junctions, the congestion charge scheme is socially beneficial, generating a net...

To facilitate efficient pavement and bridge management programs, it is important to implement practices that measure and quantify roughness at bridge approaches. It is vital to establish standardized quality indices based on quantitative approaches. Engineers can use these indices to determine the condition of a particular bridge approach and subsequently...
