Abstract: Potholes are one of the roadway distresses that negatively impact roadway safety. With emerging sensing technology, three-dimensional (3D) pavement data, derived using 3D laser technology, have become available for detecting ...

Abstract: After decades of research and development, a fully automated system for pavement crack detection with an intensity-based two-dimensional (2D) imaging data acquisition system under different lighting and low intensity ...

Abstract: Traffic signs are important roadway assets that provide critical guidance, including regulations and safety-related information, to road users. Traffic signs need to be inventoried by transportation agencies. However, the ...

Abstract: Three-dimensional (3D) laser scanners have become a mainstream technology for the automatic assessment of pavement condition. The objective of this study is to leverage highly accurate 3D pavement data to train supervised ...

Abstract: High-resolution 2D intensity and 3D range data are available to support pavement crack detection and classification. However, crack classification based on actual distress protocols specified by different state departments ...
