Road Surface Roughness Estimation Using Spaceborne Synthetic Aperture Radar [PDF]

open access: yesIEEE Geoscience and Remote Sensing Letters, 2023
Road surface roughness is a major factor that is responsible for the skid resistance of vehicles and, thus, road safety. Therefore, it needs to be monitored regularly to ensure that the roughness values are in the optimal range and to perform maintenance actions when needed.
