It was on a cloudy day in 2011 that a colleague at Windesheim brought the Doctoral Grant for Teachers, issued by the Dutch Research Councel (NWO), to my attention. At that moment, I was rather happy teaching tra c engineering and supervising students performing research on various tra c and transport topics, but had started to get homesick of doing research myself. I contacted Eric van Berkum, who was happy to help me de ne a research proposal and act as supervisor for my PhD-project. I acquired the grant and started my life as a part-time teacher and PhD-student. Combining teaching and research was often satisfying, but sometimes quite a struggle. A University of Applied Sciences o ers a very dynamic work environment, which made me seriously wander from my PhD-path from time to time. Nevertheless, with the help of my supervisors, colleagues, family and friends, I succeeded in nishing this quest. I am proud and happy to present this thesis, which re ects my interests in junction design and tra c and transport modelling.As said, this thesis would not have been completed without the help of many. The rst person I want to thank is my supervisor at the University of Twente, Eric van Berkum. Eric is a very accessible and easy going professor with a truckload of knowledge and experience, and a good sense of humour. I hugely appreciate his patience with me, especially when I repeatedly contacted him to tell him that I would not be able to spend any time on my research in the following weeks or even months. Our talks often started with some nice anecdote or the sports news of that week, before Eric continued asking fundamental questions about the purpose of the analyses and started to o er suggestions for an alternative perspective or additional analyses. It happened more than once, that after a few weeks, although I initially rejected a suggestion, discovered that it was a 'damn good idea'. In the end, Eric and Luc were able to interpret the tone of my 'hmm', whether I agreed with their comments and was inclined to do something with it. That was a crucial incentive to nally nish my project.That brings me to the second person I want to thank, being my co-supervisor, Luc Wismans. I must be careful not to praise him too much, since he will probably remind me of it. Luc's input was very valuable to me. I used his PhD-research and thesis as a template for my own. Luc was always available and willing to answer questions and very generous with his comments in draft versions of papers and thesis-chapters. I often suspected that he somehow managed to put more than twenty-four hours in his days. The only time Luc declined a meeting request was when I o ered to cook a spicy Thai dinner when we had to discuss a couple of thesis-chapters. I would advise anyone to ask Luc to be his or her (co-)supervisor.This research and thesis would not have been possible without the help of my colleagues at Windesheim. Above all, I want to thank my colleagues at the team of Spatial Planning and Mobility. Janet, Marcus, Natascha, Je rey, Hugo and A...
