Dr Federico Perrotta

Research title: Using truck sensors for road pavement performance investigation

Supervisors:  Dr Tony Parry and Dr Luis C. Neves

Personal Biography

Dr Federico Perrotta is Chartered Civil Engineer with the Italian Council of Engineers Sect.  A of Reggio Emilia and he is currently working for AECOM Ltd in Strategic Consultancy, in Nottingham. Dr Federico Perrotta obtained both his BSc and MSc degrees in Civil Engineering from the University of Parma, in Italy.  After that, Federico was awarded with a Marie Skłodowska-Curie scholarship to conduct his PhD studies at the Universty of Nottingham, in NTEC (the Nottingham Transportation Engineering Centre). This scholarship was part of the TRUSS ITN project, which was funded by the European Union under the Horizon 2020 programme.

In NTEC, Federico focused on assessing the impact of road surface characteristics on truck fleet fuel consumption through a Big Data approach. The promising results seem to indicate that further development of the method developed by Federico could help reducing the uncertainties left by the studies conducted in the past and allow future implementation of these estimates in the framework of Pavement Life-Cycle Assessment (LCA). This will help National Road Authorities to optimise their current road maintenance strategies in consideration of the extra direct and indirect costs that this can generate to society and possibly reduce the impact that utilisation of the road infrastructure has on air quality and the environment. In lieu of the developed method and brilliant results obtained with his research conduced in Nottingham, Federico received an award at the Transportation Research Arena (TRA) 2018 for the 3rd best most innovative idea in Road Transport, within Europe.
