A Tale of Many Cities
ManyCities is an intuitive and robust tool for exploring mobile phone traffic and patterns, mapped onto urban space. The application can be implemented by a wide spectrum of users – from specialized to general. Many Cities allows mobile operators to easily check the completeness of their records, to detect repeating patterns or special events and to define new development strategies. For a more general audience, the tool’s visualization output can inform collective behaviors and offer the possibility to participate and influence global trends.
The application currently browses mobile phone traffic patterns in London, New York, Hong Kong and Los Angeles during a 10 month period going from April 2013 to January 2014. More specifically, the records consist in network level counter data that includes the numbers of calls, SMS and data requests, as well as the amount of data uploaded and downloaded by subscribers (measured in Bytes and denoted in the app by "UL Data" and "DL Data"). To simplify and streamline the user experience, all data has been aggregated on the administrative areas of the target cities, which are easily identifiable spatial units.
Help the community to discover patterns and unusual gaps or outliers in the graphs! The application allows you to annotate any selected subset of the data and share your thoughts, insights or hypothesis with all users. You can also share your experience on Twitter by publishing direct link to specific map configurations. Sign in with your favorite social network account to engage in the community!
