Inferring the physical locations of social network users is one of the core tasks in many online services, such as targeted advertisement, recommending local events, and urban computing. In this paper, we introduce the Collective Geographical Embedding (CGE) algorithm to embed multiple information sources into a low dimensional space, such that the distance in the embedding space reflects the p...

The Beijing road traffic system, as a typical huge urban traffic system, provides a platform for analyzing the complex characteristics and the evolving mechanisms of urban traffic systems. Based on dynamic network theory, we construct the dynamic model of the Beijing road traffic system in which the dynamical properties are described completely. Furthermore, we come into the conclusion that urb...

Urban green spaces are very important for human wellbeing and environmental sustainability. The efficiency of managing urban green spaces often depends on communication and integration of information. We performed a social network analysis survey for assessing the communication structure among the staff in four New Delhi city parks. We were interested in the relationship between three topologic...

The urban integrated pipeline network transfers information and energies day and night for the city, therefore, the information system of urban integrated pipeline network is crucial for urban planning and management. This system provides an effective platform to store, manage and analyze the integrated pipeline network data. This paper introduces the method of constructing the system based on ...

Quality of life in urban environments is closely related to vegetation cover. The Urban growth and its related environmental problems, planners are forced to implement policies to improve the quality of urban environment. Thus, vegetation mapping for planning and managing urban is critical. Given the spectral complexity of the urban environment and the sparse vegetation in these areas, to gener...

While psychologists and ecologists have identified many factors that increase the odds of resilience in a person or an ecosystem, economic development officials and planning scholars do not yet have a firm grasp on how economic development planning relates to regional resilience. This study explores how two regions – Buffalo, New York and Cleveland, Ohio – have adapted and responded to deindust...

In Essex, EssexITS (a joint partnership of Essex County Council, Atkins and Siemens), has taken a hands-on approach to assist the County Council in carrying out its responsibility under TMA2004. EssexITS has developed a number of Integrated Urban Traffic Management and Control (UTMC) strategies to manage Essex’s road network, tackle congestion and proactively prevent or reduce the effect of con...

Intelligent Transportation System (ITS) is one of the most important urban systems that its functionality affects other urban systems directly and indirectly. In developing societies, increasing the transportation system efficiency is an important concern, because variety of problems such as heavy traffic condition, rise of the accident rate and the reduced performance happen with the rise of p...
