A German artist illustrated [video] how it is possible to create a virtual traffic jam in Google Maps by walking around the streets of Berlin with 99 cell phones. Qbertino shares a report:
Google Maps utilizes GPS and location data from mobile devices to determine if there is traffic congestion on a particular street. The app will then redirect users to less trafficked streets to avoid traffic. Using a hand cart filled with 99 active cell phones connected to Google Maps, artist Simon Weckert showed how he could create fake traffic jams in Google Maps simply by walking around the streets of Berlin. As he would be walking, rather than driving, Google Maps would perceive it to be a traffic jam due to a large number of devices reporting the same slow speed.
Google’s response to the matter, via blog 9to5Google:
Speaking with 9to5Google, a spokesperson from Google has responded to this situation to clarify a few things. In normal usage, Google does use a large number of devices running Maps in a single place as proof of a traffic jam, something this rare and very specific case took advantage of. In the statement below, though, the company does hint that it might use cases like this to further improve how Maps handles traffic data. “Whether via car or cart or camel, we love seeing creative uses of Google Maps as it helps us make maps work better over time.”
