Transport & Mobility Leuven (TML)


TML performs applied research to support policy decisions. It is our mission to help society by offering scientifically sound analyses. For this, we rely on quantitative research: modelling, statistical analyses, simulations, and prognoses. Our work fields are traffic, passenger and freight transport and the related economic impact and environmental problems. The integration between passenger and freight transport, economics and environment gives us a unique position within Europe. Transport & Mobility Leuven has been founded in 2002. Its shareholders are the K.U.Leuven and TNO. The knowledge of both institutes has been bundled and further applied to support policy decisions. The excellent relation with our shareholders guarantees that TML is always up to date with the most recent state-of-the-art. Our focus is both scientifically as practical: we are the bridge between the university and society. Our clients are the European Commission, national governments and administrations, local and regional authorities as well as sector associations and non-profit organisations. They base their policy on our analyses and prognoses. We perform our projects with great concern for independency and openness.


Key Personnel


  • Kris Vanherle

    Kris is a biochemical engineer. Following his general interest in environmental issues, he also studied for a post-master in environmental sciences and technique. He chiefly inquires into the emission determination of the various modes of transport. For the Flemish government he developed an emission modelling tool for rail, inland waterway and maritime transport to determine emission inventory and run quantitative simulations. He implemented the COPERT IV methodology for determining emissions from road traffic into the TREMOVE-model. More recently he further developed the TREMOVE model with a passenger car scrappage model and performed policy simulations with TREMOVE and worked on a study on emissions of maritime transport in Europe and abatement technologies.

  • Sven Maerivoet

    Sven holds a PhD degree in traffic engineering. He coordinated projects, organised courses and gave an abundance of lectures on the modelling, simulation, and control of traffic flows. His expertise mainly lies in transportation planning models, traffic flow theory, numerical and statistical analysis of static and mobile traffic flow data, constructing travel time loss functions, applying multi-agent systems to pedestrian flows, considering sustainability effects in cities, the related parking problems and innovative technological solutions, and the opportunities of intelligent transportation systems (ITS).

  • Lars Akkermans

    Lars holds a master in Psychology. Currently, he is working as researcher at Transport & Mobility Leuven specialised in modelling human behaviour. His main area of expertise concerns the analysis of the implications of road safety measures and (transport) policy on human behaviour, society and the environment. Before joining Transport & Mobility Leuven, he worked for the Belgian Road Safety Institute and TNO Human Factors as a researcher for different European projects related to road safety as well as an analyst of different national and international measures in the field of enforcement, human interaction and technical advances in road safety. Merging and measuring theoretical models and practical implications has been a major part of his past work in the field of traffic law enforcement.
