Big Data and Development of Smart City

Phenomenon of Smart City had its around-twenty-year development path influenced by changes in technological, social and business environment. Big Data, together with Internet of Things and Cloud Computing, has tremen- dous and profound impact on the changes of Smart City, transforming its shape and achievable goals and redefining its requirements and challenges. The aim of this paper is to study the aspects of Big Data within the Smart City concept. We analyze the past and present Smart City pilot projects, giv- ing special attention to the evolution of its traditional applications (traffic, healthcare, power grid, water & waste treatment and public safety) in the context of present technological maturity. We also describe feasible Smart City applications based on Big Data, followed by summary of benefits and main challenges, especially the growing ones, such as security of infrastruc- ture or security of private data. The final result of the study is comprehensive two-dimensional chart (technological maturity of environment vs. stage of adoption of Smart City) with identification of typical development states. The chart may help city planners selecting or creating optimized development plans of their communities.
