Routine bridge inspections in the United States are primarily conducted via visual inspection on a fixed two-year cycle. Although this strategy has generally produced a safe bridge network, a variety of research has been conducted to study enhanced inspection planning processes that could more efficiently...

Regular inspection and maintenance of culverts are critical to ensure the safe functioning of transportation infrastructure systems, preventing injuries, loss of life, and significant financial damage. Various state departments of transportation (DOTs) and the American Association of State Highway 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...

Over the last two decades many researchers have focused on providing new ideas and frameworks that can help improve conventional bridge inspection practices; however, little guidance is provided for implementing these new ideas in practice. This, along with resistance to change and complexity of the...

The recent rapid development of commercial unmanned aerial vehicles (UAVs) has made collecting images of bridge conditions trivial. Measuring a defect's extent, growth, and location from the collected large image set, however, can be cumbersome. This paper proposes a streamlined bridge inspection system...

Autonomous vehicles (AVs) that utilize LiDAR (Light Detection and Ranging) and other sensing technologies are becoming more prevalent in the transportation industry. Concurrently, transportation agencies are increasingly challenged with asset management, traffic operations, and safety assessments. The...

Bridge inspection data is an essential step in the bridge asset management operation and the bridge management system. As such, a reliability-based, holistic framework was proposed to effectively collect reliable data and perform data fusion and information fusion of sensory data used for element-level...

A high-dimensional clustering-based sampling method for roadway asset condition inspection is proposed in this study. The method complements existing literature by selecting sample roadway segments that contain multiple types of assets (e.g., signage, shoulder work, pavement marking, etc.) for the accurate...

Federal track safety regulations require railroads to inspect all tracks in operation as often as twice weekly. Railroad companies deploy expensive and relatively slow methods using human inspectors and expensive automated inspection vehicles to inspect and monitor their rail tracks. The current practices...

The most common type of bridge on South Dakota local roads is a precast prestressed double-tee (DT) girder bridge. More than 700 DT bridges are currently in-service in South Dakota. Structural detailing, aging, traffic volume, and environmental conditions affect structural performance, integrity, and...
