Google Maps

If you use 新浪财经Google Maps to plan your commutes or other travels, you might have noticed how apt the app has become at predicting traffic。 You know the fastest way out of the city might be to take the highway, yet Google tells you to the take the surface roads。 A few minutes later you’;re on your way, while the highway is packed。 An accident must have occurred half an hour earlier or a road block was just posted to make way for infrastructure works。 You’;re happy, but at the same time you can’;t help wonder: ‘;how in the world did they pull it off?’;

One of Google’;s main assets is data。 Lots of it。 If you have location services turned on (that’;s enough for Android) and Google Maps open (for Apple devices), Google will be fed with a stream of anonymous bits that speak of location, relative velocity and itinerary。 Using this data, from both car passengers and pedestrians, Google uses machine learning algorithms to predict traffic jams。 A slew of cars just started moving 30% slower than they should have? A couple minutes later Google alerts you to change your route –; a route that Google optimized taking account the constantly shifting masses of vehicles in real time。 Of course, Google can also predict the future。 Scores of historical data lends Google a clairvoyant ability。 This prediction is made based upon the data that was available on the same day, last week, last month or last year, based upon if it was a public holiday, a working day or just a normal weekend。 It can even tell if there’;s a marathon on nothing but locations data。
