Abstract

With the development of information technology and urban planning, there is a higher demand for the life quality of city people. In order to meet the demand for urban facilitation and intelligence, the research on smart city system has been widely discussed in recent years. However, existing researches mostly stay at the theoretical exploration stage, so a feasible and effective framework of smart city system which is suitable for Chinese national conditions is urgently demanded. In this paper, an implementation framework of smart city system is proposed based on city-level data exchange platform. To start with, three subsystems of smart city system are proposed and described, namely citizen-card system, intelligent transportation system, and urban regional health system. The citizen-card system is the foundation to realize smart city system, the intelligent transportation system is the core part of smart city system, and the urban regional health system is the crucial part of smart city system. Then a city-level data exchange platform and its algorithms are proposed, and the data exchange algorithms are also analyzed based on subscription and publishing mechanism. Finally, the proposed system architecture has been implemented and applied to Zhenjiang city, which is a city in Jiangsu province, China. The application performance of the proposed system architecture is also analyzed and discussed. The experimental results show that the proposed framework of smart city system is feasible and effective.

1. Introduction

At present, as the urbanization is developed so quickly, a series of social issues are emerging gradually and further affecting the development of the city, which was caused by the extensive pattern of city development including overpopulation, water sanitation, food safety, environmental pollution, and traffic congestion and so on. However, smart city (Papa, 2013) as a new strategy of city development arises at the historic moment, which not only can solve the development problem of urban construction successfully, but also can exalt the integrated competitive power of city owning to the rapid development and the thorough application of new technologies such as Internet, sensor networks, cloud computing, and mobile broadband networks (Andrea & Chiara, 2011; Cugurullo, 2013; Kheir, 2011; Sam & Peter, 2011).

As the future planning of urban, smart city aims to realize the sustainable development with the advanced information technology, and then a truly change from digital city to smart city will be actualized by using the massive information that obtained from person and sensor such as traffic information, medical data, housing and building energy consumption data (Takahashi & Okushi,2012).

To further enhance the ability of smart city, a smart city system framework is proposed based on some ubiquitous systems and the city-level data exchange platform in this paper. Firstly, three core systems of smart city are described, namely citizen-card system, intelligent transportation system, and urban regional health system. Citizen-card system is the foundation to actualize smart city system. Intelligent transportation system is the core part of smart city system. Urban regional health system is the essential part to construct smart city. Then a city-level data exchange platform and its algorithms are presented. The data exchange algorithm, which includes subscription and publishing mechanism, is analyzed and exhibited. Finally, the application performance of the proposed system is introduced and discussed. The proposed framework has also been applied in Zhenjiang City of Jiangsu Province of China.
