Solution by Arj Selvam, Uber, on Quora,
The short response is as localised as the city group needs it to be.
The surge algorithm has been iterated and tweaked many instances since it was 1st launched back in 2011 to cope with the true-time fluctuations in demand and provide. That mentioned, Uber is very, very city-particular and a ‘standard’ algorithm applied to some 80+ Uber cities these days wouldn’t hold in good stead. Alternatively, each city crew is capable to cater to the nuances of provide and demand specific to each city, and that consists of regions, neighborhoods, and blocks.
The purpose is to “surge” much less and let customers to usually reliably request a automobile.
