Keynote Speakers

Christian S. Jensen

Data-Intensive Vehicle Routing
As the society-wide digitalization unfolds, important societal processes are being captured at an unprecedented level of detail, in turn enabling us to better understand and improve those processes. Vehicular transportation is one such process, where the availability of vehicle trajectories holds the potential to enable better routing. The speaker argues that with massive trajectory data available, the traditional vehicle routing paradigm, Dijkstra’s paradigm, where a road network is modeled as a graph and where travel costs such as travel times are assigned to edges, is obsolete. Instead, new and data-intensive paradigms that thrive on data are called for. The talk will cover several such paradigms: a path-based paradigm, where travel costs are associated with paths and not just graph edges; an on-the-fly paradigm, where high-resolution travels costs are not pre-computed but are computed from purposefully selected trajectories during vehicle routing; and a cost-oblivious paradigm, where routing is done without the use of travel costs. These paradigms present new challenges and opportunities to research in routing.
Christian S. Jensen is Obel Professor of Computer Science at Aalborg University, Denmark, and he was recently with Aarhus University for three years and spent a one-year sabbatical at Google Inc., Mountain View. His research concerns data management and data-intensive systems, and its focus is on temporal and spatio-temporal data management. Christian is an ACM and an IEEE Fellow, and he is a member of Academia Europaea, the Royal Danish Academy of Sciences and Letters, and the Danish Academy of Technical Sciences. He is Editor-in-Chief of ACM Transactions on Database Systems.
