Aimed at an academic and professional audience who are in the profession of city planning, urban design, architecture and landscape architecture. Explores the potential of the metro's intervention in making a better urban future and creating a new urban tradition. Uses the city of Zhengzhou for an in-depth case study on how the metro brings innovation to urban areas. The book investigates the metro's contribution to the city, not only as a functional infrastructure but also as a project that has the potential of transforming the urban space. It explores the extreme case of Zhengzhou, which has arguably one of the most important infrastructural histories in all of China. This city, based on a railway, is switching into a new era of metro, which is going to both strengthen its old city centre and serve to further the new district development. The book contains qualitative and quantitative analysis on the speculative design for the city around the metro.
