João Santos

João Santos is currently a postdoctoral research fellow at the French Institute of Science and Technology for Transport, Development and Networks (IFSTTAR), in Nantes, developing a methodology and a software-based tool to perform life cycle impact assessments of road and railway practices. In 2016, Joao Santos received his Ph.D. in Transportation Systems from the Faculty of Sciences and Technology of the University of Coimbra (FCTUC), Portugal, in association with the Technical University of Lisbon (IST) and the University of Porto (FEUP). During his graduate studies, João Santos spent a year and a half as visiting scholar at the Center for Sustainable Transportation Infrastructure (CSTI), at the Virginia Tech Transportation Institute (VTTI), USA, where he worked on the assessment of costs and environmental impacts over the life-cycle of pavements of design and maintenance decisions. In 2011, he completed his M.S. in Civil Engineering in the Department of Civil and Environmental Engineering, at the Faculty of Sciences and Technology of the University of Coimbra (FCTUC).

In a society where the public awareness of environmental protection is increasing remarkably and the availability of resources and funding is limited, it is more vital than ever that highway agencies and decision makers (DMs) seek new tools that enable them to make the best and most rational use of these resources, taking into account environmental and social factors, along with economic and technical considerations. Striving to enhance infrastructure sustainability, his research work focus on the development of decision-support systems (DSSs) for road pavement management, which, by integrating multi-disciplinary and complementary pavement life cycle approaches, enable the DMs to properly account for, consider and assess the cumulative and long-term impacts of their decisions and practices regarding sustainability goals and targets.  This can only be achieved by employing operations research techniques and life cycle modelling approaches with a comprehensive and wide-scoped cradle-to-grave analysis capacity.

In view this, he has developed an optimization-based pavement management DSS, which includes several comprehensive stand-alone but logically interconnected pavement life cycle approaches, namely, a pavement life cycle assessment (LCA) model, a pavement life cycle costs (LCC) model, an integrated pavement LCC-LCA model, a single-objective pavement life cycle optimization model and a multi-objective pavement life cycle optimization model.

João Santos’s research interests cover a variety of topics which include:

  • Infrastructure Transportation Sustainability
  • Life Cycle Sustainability Assessment
  • Life Cycle Assessment
  • Life Cycle Costs Analysis
  • Multi-Criteria Decision Making:
    • Multi-Objective Decision Making
    • Multi-Attribute Decision Making
  • Multi-Objective Optimization
  • Single-Objective Optimization
  • Metaheuristic Optimization
  • Genetic Algorithms
  • Pavement Management

Project

Life Cycle Impact Assessment of Road and Railway Practices: Methodology and Tools

 

Supervisor:

Dr. Veronique Cerezo, IFSTTAR

Objectives:

  • Develop a software-based Multi-Criteria Decision Making  tool that implements the sustainability assessment methodology developed by and along with the remaining ER;
  • Apply the developed tool to assess and compare the sustainability of the current benchmark practices against the technologies investigated in ESR projects.
