In this MSc Thesis project, a Model Predictive Controller (MPC controller) using variable speed limits and intersection control was designed and subsequently evaluated. The design was based on combining existing control algorithms for urban and freeway networks, integrating them. While this MPC controller improved upon throughput more than MPC controllers that only used variable speed limits or intersection control, the computation time turned out to be too long for real time control and the qualitative behaviour was dubious (the controller used multiple variable speed limit areas instead of one as one would expect). More research into methods to improve upon computation time and into the behaviour has been recommended to deal with these problems.
