大规模移动数据的可用性呈指数级增长，推动了将改变我们生活的智慧城市的愿景。事实是，我们只是触及了研究挑战的表面，为了使这一愿景成为现实，应该解决这些挑战。因此，不同的研究社区（从土木工程到计算机科学）和工业利益相关者对在这些数据源上建立知识发现管道的兴趣越来越大。与此同时，这种广泛的数据可用性也提出了工业和学术利益相关者必须考虑的隐私问题。在本文中，我们对大数据在重塑城市中的作用提供了一个广泛的视角。本文涵盖了城市数据分析的主要方面，重点关注隐私问题，算法，应用程序和服务，以及来自社交媒体的地理参考数据。在讨论这些方面时，我们利用城市数据科学工具的具体例子和案例研究，在地平线2020 SoBigData计划的“公民城市”主题领域中获得的结果，其中包括一个虚拟研究环境，其中包含欧洲几个机构开发的移动数据集和城市分析方法。我们总结了城市数据科学尚未解决的主要研究挑战，以帮助实现智慧城市愿景。
The exponential increase in the availability of large-scale mobility data has fueled the vision of smart cities that will transform our lives. The truth is that we have just scratched the surface of the research challenges that should be tackled in order to make this vision a reality. Consequently, there is an increasing interest among different research communities (ranging from civil engineering to computer science) and industrial stakeholders in building knowledge discovery pipelines over such data sources. At the same time, this widespread data availability also raises privacy issues that must be considered by both industrial and academic stakeholders. In this paper, we provide a wide perspective on the role that big data have in reshaping cities. The paper covers the main aspects of urban data analytics, focusing on privacy issues, algorithms, applications and services, and georeferenced data from social media. In discussing these aspects, we leverage, as concrete examples and case studies of urban data science tools, the results obtained in the "City of Citizens" thematic area of the Horizon 2020 SoBigData initiative, which includes a virtual research environment with mobility datasets and urban analytics methods developed by several institutions around Europe. We conclude the paper outlining the main research challenges that urban data science has yet to address in order to help make the smart city vision a reality.
