Chicago wants to detect smartphones to determine pedestrian movements

The city of Chicago will launch Array of Things, a program to make the city smarter. For this, it intends to install sensors at the top of the streetlights and thus collect several information: wind, light, sound level, heat, precipitation and wind …

Most importantly, the device will detect Bluetooth connections and Wi-Fi signals from smartphones to determine the number of people present in a given geographic area. The data will then be made public on the Chicago open data site.

The measure created controversy in the city. Its inhabitants wonder about the purposes given to the program, and the data collected by it. A company London had wanted to launch such a program a year ago, but had been forced to arrest her by the authorities.
