@NaeemShehzad Google Traffic works by analyzing the GPS-determined locations transmitted to Google by a large number of mobile phone users. By calculating the speed of users along a length of road, Google is able to generate a live traffic map

Google live location, it uses the GPS of our phones, as if it is a road, how can its live location work in the middle of the city, someone "A" is going from the same road of middle city Google Using Google Maps, then Google does what, Google tracks that person "A" on this road from the speed of the person going,where he stopped at the point where person "A" is stop Google Mark it and anthore person "B" going through the same road if he stopped at that point then Google confirm that there is same traffic issue . if person "A" is keep going without stop then it confirmed for Google that there is no traffic issue then Google gives Green Line if any stop or halt with one more "GPS" At same same point then it gives red line .. Google Live Traffic Just works like this
