Transport and telecommunication behaviour, modelling, planning and evaluation methodology in the domain of transport. These involve methodological developments of survey methods and microsimulation modelling – in particular in the fields of transport communication and telematics – as well as the development of environment-friendly and sustainable schemes for urban and long distance travel and their implementation.
