The Process Behind the Scenes. Uber has a massive database of drivers, so as soon as you request a car, Uber’s algorithm goes right to work – in 15 seconds or less, it matches you with the driver closest to you. In the background Uber is storing data for every trip taken — even when the driver has no passengers.

Which algorithm Uber uses?

So many uber cars on the road send GPS locations every 4 seconds, so to predict traffic we can use the driver’s app’s GPS location data. We can represent the entire road network on a graph to calculate the ETAs. We can use AI simulated algorithms or simple Dijkstra’s algorithm to find out the best route in this graph.

How Uber optimized its dispatch system?

The dispatch system has a third service, called Disco (Dispatch Optimization), whose main function is to match supply and demand. Disco enables Uber to “look into the future” and to use information as it comes in. For instance, the old dispatch system only looked to current available supply.
