time=net.work was born in order to measure and evaluate transportation network complexity. As the author explains: "After having read the amazing A. L. Barabasi's Linked, I decided to develop some new approaches towards networks dynamics. How Ordered are they? How Small are they? How Robust are they?".
According to Fabio Lamanna, during the last years many physicians have been interested in transportation network analysis, laying the theoretical basis for extending complex network knowledge to real dynamical systems. Time=net.work tries to apply and verify physical theories on real systems, using timetable data of real moving entities under fixed constraints.
The main subject of study for the time=net.work project has been the Berlin urban network, consisting of U-Bahn, S-Bahn and Regional Bahn lines; strongly interconnected with Bus, Strabenbahn and Metrotram vehicles. The complex network approach requires a simple tool to analyse the dynamics of different transportation modes on real infrastructures. The image shown here represents the distribution of travel times and betweenness centrality of the entire Berlin transportation network.
