This statement and the statements below build on the assumption that these data is available and usable. Frameworks and platforms are needed for this and there is the challenge of the local rooting of public sector bodies and their operations: this is not homogenous across the EU or the world.

It is really improtant to understand that real-tie data are really hard to find, but even if there were real-time data there are other constraints such as security and privacy issues. I think this is something to be figured out in a state- country or even European level.

I see real-time data only as a result of sensors...
