Berlin-based Simon Wakert posted a video of the feat (see below) on his YouTube account. The video shows him carrying 99 smartphones in a small cart in front of Google’s office and on a few streets in Berlin. The 99 smartphones in his hand cart run at the same time at slow speeds Google Maps The road showed traffic jams while the road was completely empty.
Google Maps calculates the smartphone data of the users inside the trains on the route and displays the traffic status on the route accordingly. These data include the speed of the vehicle and the number of smartphones on that route
If a number of smartphones run at a slower pace on a route, Google displays slower traffic in this area. If the number of smartphones is too high and the speed of trains is too low, the traffic jams in that area are shown on the map. Google shows the status of traffic through color. If the traffic is clear then the green line is present and in case of slow speed orange color and if there is traffic jam then the red line is present.
Wickert’s video shows that the color of the street first appeared green, and when he circled the slow motion on that road with 99 smartphones, the color changed from green to dark red on the map. Wickert did not share too much information about this strategy. In that case, this video cannot be considered completely reliable. But if this video is true, then Google should pay attention to it and fix the system.
