1. A method for predicting future travel times of a target vehicle traveling on a route from a starting point to a destination, comprising the steps of:
- acquiring real-time probe data by probe vehicles traveling on a set of one or more alternative links, which are substantially parallel to the route traveled by the target vehicle, from the starting point to the destination;
estimating a current travel time for each alternative link using the real-time probe data; and
predicting the future travel time of the target vehicle traveling on the route based on the current travel times for the set of one or more alternative links using a set of regression functions, wherein each regression function is

Abstract
Future travel times of a target vehicle traveling on a route from a starting point to a destination are predicted by first acquiring, by a probe vehicle, real-time probe data to alternative links from the starting point to the destination. Then, the future travel time for each link is predicted using a set of regression functions.
