New Perspectives on Global Human Traffic: Scaling Laws, Emergent Geographic Communities, Geocaching and Trackable Items
Travel in our globalised world has reached a complexity and volume of unprecedented degree. More than 60 million people travel billions of kilometres on more than 2 million international flights each week. Hundreds of millions of people commute on a complex web of highways and railroads most of which operate at their maximum capacity. Human mobility is responsible for the geographical spread of emergent human infectious diseases and plays a key role in human mediated bioinvasion, the dominant factor in the global biodiversity crisis. I will report on the discovery of scaling laws in global human traffic, present a complex network perspective on multi-scale human traffic networks, report on their statistical properties and show that they can be used to identify geographically coherent communities which only vaguely resemble those provided by geopolitical ones. I will discuss aspects of European transportation networks, geocaching and trackable items.
