In 2007 Jan-Dirk left Imperial College London, taking up a visiting position at Tokyo Institute of Technology before moving to Kyoto in 2010. Jan-Dirk’s current research interests focus on long-term demand adaptation to transport infrastructure investments. A main research focus remains further passenger behaviour and public transport assignment.
