Analysing Ireland's Social and Transport Networks using Sparse Cellular Network Data

This work utilises data from a mobile phone network to observe the com- munication and movement patterns of the Irish population between specic locations. A novel technique is applied to mobile phone network billing data to estimate the distri- bution of the phone network population across the country at key times, namely home times and work times. From these population distributions, sets of weighted trans- portation and communications links between locations are generated. These networks are analysed using indicators commonly employed in network theory such as cluster- ing coecients and betweenness centrality. Furthermore, the ability to generate such weighted links when phone network data is unavailable is investigated.
