Back-end system

New procedures were added to process the big amount of daily information gathered by the system processed in a back-end, not only to receive but also to provide a way of powering the future data visualizations.

After some weeks, a few comparisons were made with our daily counts and ground truth from the airport with the passenger counts, we found staggering correlations above 90% between these data sources.

Analysis

In the last weeks, a few successful tests were made to detect unusual events in the different locations, based on the number of daily devices. Those events were later compared with updated ground truth data from the airport to match the results and fine tune the algorithm parameters.

Upon receiving the authorizations, 4 more Wi-Fi routers were installed in specific touristic points of Funchal, and we were also authorized to install them in the entry points of the island in collaboration with the airport and port.

Further features were added to visualize the flow of people between the different spots in the city and inbound vs outbound movements. Attempt to develop nationality detection techniques based on the gathered information and SSID profiling.

First results

Today we achieved a milestone in the course of this project, as we created the very first visualizations for the data that we’ve been gathering. It is already interesting to notice some patterns in the everyday device count and flow.

Holiday Testing

For the holiday celebrations, Miguel set up a few wifi routers in the city of Funchal, placed in specific interest points, such as the market, city squares and so on. Given that the holidays bring a lot of movement to the city center, this proved to be a good way to do stress tests on the platform.
