‘At least for Europe it is obvious: All roads lead to Rome! You can reach the eternal city on almost 500.000 routes from all across the continent. Which road would you take? To approach one of the biggest unsolved quests of mobility, the first question we asked ourselves was: Where do you start, when you want to know every road to Rome? We aligned starting points in a 26.503.452 km² grid covering all of Europe. Every cell of this grid contains the starting point to one of our journeys to Rome. Now that we have our 486.713 starting points we need to find out how we could reach Rome as our destination. For this we created a algorithm that calculates one route for every trip. The more often a single street segment is used, the stronger it is drawn on the map. The maps as outcome of this project is somewhere between information visualization and data art, unveiling mobility and a very large scale.’ Beautiful! Decent-sized prints available for 26 euros too.

EU counter-terror bill is ‘indiscriminate’ data sweep
“To identify if someone is travelling outside the EU, we don’t need an EU PNR. This data are already easily available in the airline reservation system,” [Giovanni Buttarelli, the European data protection supervisor] said. EU governments want more information in the belief it will help law enforcement in tracking down terrorists and are demanding access to information, such as travel dates, travel itinerary, ticket information, contact details, baggage information, and payment information of anyone flying in or out of the EU. … EU PNR data would be retained for up to five years
