Bus rapid transit systems and beyond Exploring the limits of a popular and rapidly growing urban transport system David Sorg Advising Professor: Prof. Dr. Ulrich Weidmann, IVT ETH Zürich Supervisor: MSc ETH SD&IS Nelson Carrasco, IVT ETH Zürich Master Thesis MSc in Spatial Development and Infrastructure Systems July 2011 Bus rapid transit systems and beyond ________________________________________________________ July 2011 Acknowledgements I want to thank the following persons for their highly appreciated contributions and inputs. This work would not have been possible without their valuable support. Prof. Dr. U. Weidmann and Nelson Carrasco benevolently accepted to supervise this master thesis and assumed this task with great enthusiasm and commitment. Their con- stant and competent support, feedbacks, suggestions, and critique vitally contributed to guide and improve this work. Nicolas Leyva, Wolfgang Forderer, and Patrick Daude from the network „cities for mo- bility‟ in Stuttgart helped to develop the idea of this work. Their interest in the findings and results greatly contributed to the motivation and impetus that guided this work. Rebecca Bechstein, Flurin Feldmann, Gerold Signer, and Reto Rieder made crucial con- tributions to the quality of this work by their patient and persistent support in proofread- ing, commenting, and correcting. In exchange, they are experts in BRT systems by now. Finally, my family and close friends always provided invaluable support, backing, and motivation during my entire studies. Without their help, all this would not have been possible.
