<P> 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 processes the incoming raw data about mobile phone device locations , and then excludes anomalies such as a postal vehicle that makes frequent stops . When a threshold of users in a particular area is noted , the overlay along roads and highways on the Google map changes color . </P>
