A Visual Analytic System for Longitudinal Transportation Data of Great Britain

It is a known fact today, that globalization has increased the opportunities around the world and more so in the urban areas. As a result, there is high concentration of population in all urban communities around the world. In order to meet these needs, public transportation systems have been developed at a fascinating pace around the world. This leads to a vast amount of transportation data. Now researchers and practitioners are digging in to find new ways to improve it further. In this paper, we explore the longitudinal transportation data of Great Britain and visually compare changes and trends over the years. We try to answer to what extent the transportation network has directly impacted the population and job distribution in major cities of Great Britain, and vice versa. We also aim to evaluate potential issues in the current services, such as the potential accumulated delay due to the overlapping services. We provide flexible search queries, allowing users to interact with different aspects of city geography and dynamically see the changes taking place at those locations. Finally, we present a series of case studies and report some interesting findings
