Book excerpt: Public Mobility Systems deals with real case studies relating to mass transport, rapid transit services, carpooling measures and car sharing strategies. The included papers present case studies from all over the world including: Zagreb, Croatia; Mexico City, Mexico; Holy Makkah, Saudi Arabia and the Gauteng region of South Africa. Papers are also included which relate to the more theoretical aspects of transit systems, which span general methodology, the latest advancements and model analysis. It is well-known that model development cannot replace a deep knowledge and understanding of real world phenomena and human experiences. To this end, the book collects fragments of public mobility systems both from international practices and academic theory, in an effort to share current research and ideas to progress and lay the groundwork for future innovations. The book will be of interest to research and academic organisations as well as practitioners, especially in large civil engineering consultancies. Many papers from the book can also be used as advanced background reading in graduate courses on transport studies and traffic engineering.
