9、i Supplement 28 to ITU-T Y-series Recommendations ITU-T Y.4550 series Smart sustainable cities Integrated management Summary Supplement 28 to ITU-T Y-series Recommendations proposes an integrated management solution for smart sustainable cities. With integrated management for smart sustainable citie
10、s (IMSSC), sensors, nodes and models can function in an organized way. As a result, when emergency events occur, the data, models and other resources needed, can be rapidly discovered and acquired. To achieve the goal of making a city smarter and more sustainable, the first step is to analyse real-t
11、ime processes and understand event patterns through event modelling. Additional capabilities, in terms of processing units, application units, as well as models, might be needed. The second step is to fuse processing so that different sources of observation can be combined together to compensate the
12、ir own deficiencies and attain the goal more efficiently. Finally, services for information resource publishing and sharing as well as result fusing are also necessary to disseminate information across the concerned agencies. By adopting the integrated management system, each city can take a big ste
13、p towards the implementation of the smart sustainable city vision.

26、tion 0.1 Background “A smart sustainable city is an innovative city that uses information and communication technologies (ICTs) and other means to improve quality of life, efficiency of urban operation and services and competitiveness, while ensuring that it meets the needs of present and future gen
27、erations with respect to economic, social, environmental as well as cultural aspects“. The above definition describes what a smart sustainable city should be. However, significant urban challenges such as security, criminality, pollution, traffic congestion, inadequate infrastructure and response to
28、 natural hazards continue to prevent this vision from becoming a reality. Some examples of the challenges faced by cities are listed in Figure 1. Figure 1 Examples of challenges faced by cities In order to successfully address these challenges, cities should take into consideration the deployment of
29、 the necessary tools to be able to monitor, map and report what is happening in real time. An effective reporting mechanism will ensure that such problems are tackled rapidly to avoid or reduce possible causalities and economic losses b-Namb. As part of a recent widespread urban digitalization proce
30、ss, several cities have deployed a variety of sensors, including cameras, rain gauges and pressure transducers, etc., in order to be able to acquire first-hand information about all of the citys operations in a timely manner. Even if all this information is available in cities, it is unfortunately d
31、istributed through different departments or even regions and an effective management mechanism is still lacking. In response to this challenge, this Supplement proposes integrated management for smart sustainable cities (IMSSC). With IMSSC, the sensors, nodes and models can function in an organized
32、way. As a result, when emergency events occur, the data, models and other resources 2 Y series Supplement 28 (01/2016) needed can be rapidly discovered and acquired. To achieve the goal of making a city smarter and more sustainable, the first step is to analyse real-time processes and understand eve
33、nt patterns through event modelling. Additional capabilities, in terms of processing units, application units and models, might be needed. Secondly, there is a need for fusion processing guidance, so that different sources of observations can be combined together to compensate for their own deficien
34、cies and attain the goal more efficiently. Finally, services for information resource publishing and sharing as well as result fusing are also necessary to disseminate information across the concerned agencies. By adopting the integrated management system, each city can take a big step towards the i
35、mplementation of the smart sustainable city vision. 0.2 Service framework The users involved in IMSSC are not only municipal departments, but also enterprises and citizens. Municipalities are usually in charge of the daily operation and maintenance of IMSSC which is initiated by them. When emergency
36、 events occur, they need to synthesize all the information and make proper decisions to rescue lives and reduce economic losses. Citizens are the users and main beneficiaries of integrated management for smart sustainable cities. They are able to report problems of daily management and emergencies,
37、as well as receive notifications from the municipal authorities. Enterprises can be viewed from two perspectives, some enterprises can take part and assist the municipality to improve the capacities of the integrated management, other enterprises can act simply as ordinary citizens to do the work of
38、 reporting or notice feedback. The service framework of IMSSC is represented in Figure 2. Figure 2 Service framework of IMSSC Y series Supplement 28 (01/2016) 3 0.3 Intended application The proposed integrated management for smart sustainable cities aims at tackling four main types of problems, name
39、ly inadequate safety and security protection, increasingly worsened urban environment, damaged city infrastructure and natural or man-made emergency events. In this Supplement, these four types of problems are represented as theoretical events through a uniform event information model. They are dete
40、cted by sensors, recorded by observations, analysed and processed by models and finally settled by a decision made according to nodes. The goal of IMSSC is achieved through the direct management of information resource carriers, events, sensors, observations, models and nodes. The roles of the diffe
41、rent information resources in IMSSC are presented in Figure 3. Figure 3 Roles of the different information resources in IMSSC These information resources represent the crucial infrastructure for real-time monitoring of city dynamic processes. However, these resources have not yet been efficiently us
42、ed due to the lack of a unified management of the observation resources and information carriers, the lack of rapid and smooth processing of information and the lack of real-time publishing and sharing services. As a consequence, the interconnection among the different city departments has not yet b
43、een established. This is a missed opportunity for every city administration as events such as traffic congestion, urban flooding and pipeline leakage that existed before continue to perpetuate. The operational efficiency of cities is not always as satisfying as it could be, affecting negatively citi
44、zens quality of life. Therefore, it is imperative to implement IMSSC in order to resolve each of the challenges described above. 4 Y series Supplement 28 (01/2016) IMSSC is used to model the information resources of cities uniformly, fuse the data from the information resources to acquire a higher l
45、evel of information and share the information to serve people in cities b-Nama. In this Supplement, information resources are composed of nodes, sensors, data, models and events, among which nodes include sensing nodes, processing nodes and application nodes and sensors are affiliated to sensing nod
46、es. The fusion process aims to fuse the information resources with toponym and maps respectively. Services mainly include data, model and event services. IMSSC is able to ensure the well-organized and efficient operation of people, things and streams in cities, so that disastrous events can be detec
47、ted in advance and can be avoided in a timely manner before their occurrence. In this way casualties and economic losses can be reduced as much as possible. At the same time, IMSSC is able to provide solutions for widely-existing problems, such as traffic congestion and environmental pollution, etc.
48、, improve the living quality of citizens, protect the environment and implement the sustainable development of cities. 1 Scope The objectives and challenges of IMSSC, as well as the technologies used to address the problems and to achieve the goals of smart sustainable city development are illustrat
49、ed in clause 6. The specific meta-models, fusion processing workflows and services proposed for IMSSC are presented in clause 7, while clause 8 provides examples pertaining to the application of meta-models, fusion processing workflows and services for IMSSC. 2 References None. 3 Definitions None. 4 Abbreviations and acronyms This Supplement uses the following abbreviations and acronyms: 4A Anytime, Anybody, Anywhere, Anything 4R Right time, Right body, Right place, Right thing EML Event pattern Markup
