Definition and Validation of a Method for Identifying Road Surface Anomalies on Streets by Measuring Noise and Vibration

Abstract

This work was created in order to present an automatic methodology for detecting anomalies on the road surface, based on data provided by a noise dosimeter and a vibration dosimeter, both of which were synchronised with a smartphone with a geo-locator (GPS). There have already been studies on this subject, particularly to identify objects in the subsoil or to recognise the stratigraphy of bituminous conglomerates that make up asphalt road paving, but no one has looked into the possibility of identifying road surface anomalies through the analysis of sound pressure levels or acceleration levels that can be registered on board of a vehicle that runs along a stretch of road. Along this sense, once tested and validated, this survey approach allows for the identification of road anomalies in a specific route using a single survey and the combined use of measuring instruments.
