ITU‐T's Technical Reports and Specifications 653 Integrated management for smart sustainable cities Executive summary This Technical Report has been developed within the Focus Group on Smart Sustainable Cities (FG‐SSC) and provides a technical proposal for integrated management, which can be followed by any municipality interested in improving the management of its infrastructure, operations and citizen interactions, and in addressing critical urban challenges – such as security, criminality, pollution, traffic congestion, inadequate infrastructure, and response to natural hazards. Information and communication technologies (ICTs) proved to be instrumental to support urbanization and allow the transition towards smart sustainable cities. The rapid proliferation of ICT products and solutions in cities has led to the lack of uniformity in tools, such as information representation methods, software interface specifications, etc., posing additional challenges to urban management practices. Integrated management for smart sustainable cities (IMSSC) seeks to alleviate challenges in the smart sustainable cities management through the incorporation of sensor web, model web, service interfaces, ICT products, Internet of things (IoT) as well as the cloud computing technologies in areas of city operations and management. Integration of such technologies is adapted to continuously resolve the problems in smart sustainable cities management by encoding, fusing and sharing the information resources of the cities in a unified way. Recognizing the impact that IMSSC can have on the city management, the International Telecommunication Union (ITU) established the Focus Group on Smart Sustainable Cities (FG‐SSC) with the vision that cities worldwide can be empowered to alleviate and overcome management challenges effectively and become smarter and more sustainable. By promoting the coordinated development and management of smart sustainable cities, IMSSC allows cities to maximize socio‐economic institutions as well as keep the city operate in an orderly way. However, in order to realize the orderly operation of all relevant sectors in the cities, a series of technical specifications are essential. Thus this Technical Report aims at emphasizing the management problems faced by cities and at providing IMSSC as a possible solution to mitigate such challenges, with the goal of generating further dialogue and discussion.
