Abstract
Techniques are described for generating predictions of traffic conditions at one or more indicated times, such as by using probabilistic techniques to assess various input data while producing predictions for each of one or more road segments (e.g., in a real-time manner based on changing current conditions for a network of roads in a given geographic area). In some situations, one or more predictive Bayesian models and corresponding decision trees are automatically created for use in generating the traffic condition predictions for each geographic area of interest, such as based on observed historical traffic conditions for those geographic areas. Predicted traffic condition information may then optionally be used in a variety of ways to assist in travel and for other purposes, such as to plan optimal routes through a network of roads based on predictions about traffic conditions for the roads at multiple times.
