Abstract
Method and system for prediction-based navigation in a real-time distributed navigation system. In one embodiment, a server receives a request from a client comprising one or more position coordinates. The server estimates the user's speed, estimates total elapsed time, calculates an optimal route to the destination and sends a set of routing directions to the client. Moreover, the server estimates a route origin within an estimated comfort zone in order to calculate the optimal route from the estimated origin to the destination.
