Integrated Traffic Control Design

In this thesis a modular code skeleton for combining Variable Message Signs (VMS) and Adaptive Cruise Control (ACC) as a combined system are being presented. Basic control theory for the two control types are given with corresponding pseudo code. Also simulation with the different controllers are compared and discussed. Finally some tips and tricks regarding the simulation software VISSIM are given. Even tough the simulation software VISSIM is in the focus, this thesis can be used to support implementation of combined controllers in other software as well. Important to note is that the controllers implemented are merely to verify that the code skeleton is working. In other words, the simulation results presented in this thesis are not to be used when judging the performance of a controlled network. Acknowledgements There are many people I would like to thank for supporting me while doing this master’s thesis, so thank you all, you know who you are. But there are some people I would like to mention especially since their help have been very important. First I would like to thank Stefan Pettersson at Viktoria Institute for accepting me as a master’s thesis student at the company and providing me with necessary contacts, a working area and support on regulator questions. A big thank also goes to János Polgár for a tremendous help with getting me into the VISSIM software and how to program the different modules. Also a huge thank you goes to Adam Balázs Kulcsár who made this thesis possible both by giving me the idea for it and for, during the whole project time, committed and wholeheartedly helped and guided me in the right direction based on his great knowledge and experience in the field of traffic control. Another thank goes to Koenraad Verduyn and his colleagues at PTV Vision for helping me with the VISSIM license and for assistance in some software and programming issues. Finally, I would like to thank my lovely girlfriend Maria for cheering me up when it sometime felt hopeless and for listening on my chatter about traffic during this project.
