2011: Development of a system to control the weather and mudslides destroying areas of the city

The experience of introducing Smart City class solutions in Rio de Janeiro is indicative. The decision on the need to organize Rio Operations Center in the city arose after another mudflow from the hill on which part of the urban areas were located. Due to heavy rains, the mudslides went quite often, but one of them turned out to be especially destructive, many people died, houses were destroyed. By agreement with IBM, the city administration decided to organize a center to which information would flock about the weather, soil condition, traffic situation, etc. - in total, more than 30 departments were supplied to the center and, accordingly, it became possible to provide feedback by linking all these departments.

Now, when receiving information about the approaching heavy rain, city services know exactly to which site the maximum number of rescuers should be sent, where it is necessary to quickly organize the evacuation of people, which routes are better to use, etc.

In November 2011, the system was still improved: the system of warning city authorities and emergency services about changing weather conditions was automated (before that, alerts were sent out manually). In addition, information from the Rio Operations Center is published daily on social networks and sent to users' mobile devices. In addition, constantly updated weather reports, road conditions and other useful information are published on Facebook and Twitter. See also: IBM Smarter Cities.
