Abstract: A safety performance function (SPF) is a statistical equation to predict the expected crash frequency for a certain roadway facility, mainly as a function of traffic exposure indicators. Roadway characteristics, such as ...

Abstract: Even though 30% of the annual highway fatalities originate from inferior roadway conditions, crash costs under regular operations have seldomly been included in the life cycle cost analysis (LCCA). Among the various condition ...

Abstract: A standard interchangeable data format was recently developed through the Transportation Pooled-Fund Study TPF-5(299) to meet different requirements and needs for two- and three-dimensional (2D/3D) pavement image data ...

Abstract: Monitoring pavement conditions using crowdsourced vehicular data can significantly contribute to real-time and cost-effective pavement maintenance decision-making. This paper presents the development of various machine ...

Abstract: Periodic bridge deck inspection is critically important in bridge management and maintenance. This paper presents a comprehensive bridge deck evaluation using sub-mm three-dimensional (3D) laser imaging technology in a ...

Abstract: Pavement friction and surface texture are crucial for highway safety. Acknowledging the gaps in understanding the relationship between pavement surface friction and texture, this paper introduces a novel deep residual ...

Abstract: Image-based systems are becoming popular to collect pavement condition data for pavement management activities. Pavement engineers define various distress categories based on pavement types. However, software solutions ...
