Method, system and computer-readable storage mediums for estimating a route

The method estimating said route between an origin location and a destination location of a cell phone user requesting said route by using a computer device receiving as inputs location data from a base station tower, said computer device: creating a plurality of perturbations of at least one of said computed origin or said destination location within said base station tower coverage; for each perturbation created querying a route calculation engine, based on geospatial data, to calculate a route between said perturbations or between said perturbations and said origin or destination and obtaining a list of routes, and choosing among said list of routes an optimal route by maximizing an utility function that assesses the efficacy of each route of said list of routes by using user's location data being performed within certain distance of said calculated routes.
