Using accident alert data reported by Waze, positions of the city guards - captured from the devices they use - and the locations of the mobile radars, the data intelligence office was able to locate areas in which accidents occurred in greater numbers.

The data also showed that accidents index was higher at locations furthest from radars and that city guards at some of these locations would be present in larger numbers only after accident schedules. The data were sent to the Municipal Guard and to the Traffic Engineering Company - CET-RIO to evaluate the adoption of new measures.
