Conclusions

I2U information flows is used, in this work, to simulate
urban phenomena
Simulation needs digital information from cities and its
own feedback
Previous and exhaustive information analysis and
clasification its fundamental to start any kind of urban
cloud computing
Future Work

Use Complex Systems
methodologies to analyse and
to compare events and
simulations
To detect emergent
phenomena in digital cities by
means of simulation and Data
