Spectroscopy, which is a study of interactions between matter and electromagnetic radiation that has been around for decades, provides a way of analyzing materials. Its methods can tell us exactly what a material contains and can produce unequivocal results that make it possible for highway agency personnel to quickly determine whether a material is or is not...

Pedestrians’ acceptance of automated vehicles (AVs) depends on their trust in the AVs. We developed a model to promote pedestrians’ trust in AVs through implicit communications. To empirically verify this model, we conducted a human subject study with 30 participants in a virtual reality environment. The study manipulated two factors: AV driving...

Travel demand management (TDM) is being implemented in numerous different ways throughout the world, to address congestions issues and encourage modal shift. This research outlines some of the many TDM strategies being used internationally to provide insights of potential value for the New Zealand context. This information is presented through six city case...

With the increased use of electronic devices, distracted driving is assumed to be one of the main causes of crashes. The Illinois Department of Transportation (IDOT) has demonstrated interest in addressing distracted driving. However, the real impact of distracted driving on traffic crashes in Illinois is still unclear because of what appears to be a lack of...

This study demonstrated that Type 2205 stainless steel strand can be used as a replacement for conventional ASTM A416 steel strands where an increase in service life is required. The benefit and practicality of using Type 2205 stainless steel strand in prestressed piles were determined from two tasks performed in this study.
First, a corrosion...
