One of the challenges municipalities face when trying to prevent parking problems is the difficulty of predicting the effect possible policy implementations will have on the parking occupancies. Therefore, a conceptual model was developed that uses the interactions between parking supply, demand, and choice behaviour to forecast the parking occupancy. In this research, this model is operationalised using existing data and techniques to form an operational model framework. The framework is tested and validated using a case study on the Dutch municipality of The Hague. While there are many ways the model can still be improved and further developed, the framework developed in this thesis shows that the underlying concept is able to accurately describe the balance between parking supply and demand and, from that, predict the resulting parking occupancies. It combines several existing techniques and data sources with some new techniques, providing an initial step to a full parking occupancy model. ... Read more

Metalenz is a spin­off company of Harvard University that works on finding newer and better designs for lenses. To prevent manufacturing designs that might not work, they first want to run computer simulations on their designs. This research focuses on a possible method for these simulations using a test case as design. It turns out that the simulations work, but that they are slow. Therefore, a technique to make the simulations faster, Multi-trace boundary integral equations, is researched. This technique manages to change simulations that take a week to finish into simulations that take a couple of hours to finish. Before Metalenz can start using the simulation techniques, they should be tested for more complicated cases, to make sure they still
work when more factors are at play ... Read more
