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
