Road safety is a crucial topic of transportation engineering. The Wyoming Department of Transportation (WYDOT) collects such data from police crash reports and roadway inventories. WYDOT also provides those data to its partner groups in the form of data records or summary statistics documented in periodical...

 

This study aims to improve the efficiency of driven piles in intermediate geomaterials (IGMs) to increase the reliability of pile foundations for bridge structures. Test pile data collected from the seven state DOTs and total 223 pile load test data are evaluated to provide recommendations for driven...

 

Understanding the condition of roadway assets is important for transportation agencies to plan for future improvements and asset management purposes quantitatively. Since these assets are distributed across the country, a manual data collection system falls short of the automated methods due to time...

 

Motorcycle riders and passengers are much more likely to be killed or severely injured in a crash, and on average, about 15% of all traffic fatalities include motorcyclists. The study uses 12 years of motorcycle crash data (2008–2019) from Wyoming, and eight years of data from Utah (2014–2021) and...

 

Several approaches are presented that allow for a direct path of image-to-analysis for the mechanics of structures using a combination of structure-from-motion (SFM) and the finite element method. Through these methods, conventional computational methods can be applied to models created from digital...

 

The objective of this study was to determine the effectiveness of commercially available polymer soil stabilizers in expansive soil swell reduction relative to quicklime and Class C fly ash. A survey of state departments of transportation within the Mountain-Plains region of the United States (Colorado...

 

This report presents a comparative experimental study on the axial behavior of concrete subjected to alkali-silica reaction (ASR) with and without confinement by carbon-fiber reinforced polymer (CFRP) sheets. A total of 120 cylinders are cast using two types of coarse aggregates to represent variable...

 

The emergence of a new mode, mobility as a service (MaaS), has, to date, been most often characterized as the ride-hailing mode provided by companies such as Uber and Lyft. This study focuses on MaaS as a transit access mode. This mode is also referred to as microtransit. For this research, we describe...

 

Older adults, people with disabilities, individuals in low-income households, and those living in rural areas can face significant mobility challenges. This study examines travel behavior and mobility of these transportation-disadvantaged groups, including trip rates, miles driven, mode shares, and other...

 

Railroad accidents can cause economic harm that extends far beyond their own financial losses. As one of the most efficient modes of long-distance freight transportation, losses in line capacity and cargo due to accidents can disrupt the supply chain and lead to commodity shortages everywhere. Therefore...
