One of the projects with the greatest impact in the city of Rio de Janeiro was the replacement of the Perimetral Viaduct, one of the most important roads to the municipality. For this project, the big data team used GPS data from buses and bottlenecks from Waze to measure roadway impacts.

These data were used to identify the sites most affected by the changes in the first week of closure, allowing them to be corrected prior to the final removal of the viaduct. The data from Perimetral environment also served to produce monthly reports sent to the Public Prosecutor's Office and to the Judiciary, which accompanied the entire evolution of the recovery of the area currently known as Porto Maravilha.
