Research team develops 'smart scanning' technology to detect potholes

A UK-based research team is developing ‘smart scanning’ technology to detect the early signs of potholes and predict their severity. The technology, developed by a team led by Dr Senthan Mathavan of Nottingham Trent University (NTU), scans roads for raveling – the loss of aggregates from the asphalt that leads to potholes and cracks (pictured). Combined with 2D and 3D scanners on a pavement-monitoring vehicle, a machine vision algorithm can examine the road with accuracy at traffic speed during day or night. The system works by detecting different textures of the road to identify raveling and distinguishes it from shadows and blemishes, such as tire marks, oil spills and recent pothole repairs. During the research, the team found that the technology detected road surfaces correctly in all 900 images tested. It took approximately 0.65 seconds to 3D process the raveling measurements, but it is believed that this could be reduced further.

The research has been published in Transportation Research Record, a leading academic journal for transportation infrastructure research. As well as Dr Mathavan, the research team has also involved: Dr Mujib Rahman of Brunel University; Dr Khurram Kamal of the National University of Sciences and Technology in Pakistan; and Martyn Stonecliffe-Jones of Dynatest UK Ltd, a pavements engineering specialist, which manufactures a range of road testing vehicles. Commenting on the results of the testing, Dr Mathavan, said, “It’s imperative for authorities across the world to be able to monitor road conditions efficiently and safely. For the first time, academic research has addressed the issue of detecting raveling in an automated way, which has led to the development of this novel software that can be used across the industry.”

Dr Rahman added, “Potholes, in their worst form, can create dangerous driving conditions and cause costly damage to vehicles. What this technology allows us to do is capture better quality information on road conditions, without disrupting the flow of traffic or incurring unnecessary costs. This could be a significant step forward in the way that potholes are managed, helping improve the timeliness and efficiency of repairs.”
