The first invisible information that is possible to see from this photo is that in this zone of Bologna there are a lot of people that work here during daytime, this statement can be done by observing the great number of buildings full of office and other commercial spaces. The second invisible information is that in this area there is a great air pollution, this aspect comes from the fact that a great traffic flow automatically generates a lot of gases harmful for human health. The fact that there is a great air pollution can become knowledge and can help to create more livable urban spaces, because, if this fact is known, authority can make some interventions in order to limitate the private traffic flows in this area, reducing in this way the pollution; for example in my opinion a good solution could be the implementation of a wider and more capillary public transportation system.
