Automated Spatial Progress Monitoring for Asphalt Road Construction Projects
… detect incremental progress on road design layers in 3D as-built point cloud data generated using unmanned aerial photogrammetry and a novel data simulation approach. A parallel as-planned progress estimate is also automatically prepared using 4D information, and the progress status …

Cross validation of observations from the GPM dual-frequency precipitation radar and dual-polarization S-band ground radars
… extensively used for validating DPR's melting layer detection capability in different types of precipitation system. In this study, a new method developed by Le et al (2017) for identification of snow falling on the ground has been considered. Ground validation comparisons have been performed …

The Application of Laser Technology for Railroad Top of Rail (TOR) Friction Modifier Detection and Measurements
… optical sensors as they relate to detecting thin layers is presented, as well as a literature review of the significant aspect of surface roughness on optical signature. Both commercially available optical sensors and optical devices, such as independent lasers and detectors, are examined in a …

Development of Data Analysis Algorithms for Interpretation of Ground Penetrating Radar Data
… by accurately knowing the existing pavement layer thicknesses and localization of subsurface defects. Currently, the majority of departments of transportation (DOTs) rely on coring as a means to estimate pavement thicknesses, instead of using other nondestructive techniques, such as Ground …
