Dynamic time series prediction of traffic conditions
First Claim
1. A computer-implemented method comprising:
- receiving, by a configured computing system, first information indicating current traffic conditions at a first time for one or more road segments that are at least some of multiple road segments for one or more roads, and second information indicating other conditions that affect traffic on the one or more road segments;
using, by the configured computing system, the indicated current traffic conditions and the indicated other conditions to automatically predict traffic conditions on at least one of the multiple road segments at one or more second times; and
providing, by the configured computing system, one or more indications of at least some of the predicted traffic conditions for use in facilitating travel on the one or more roads.

Abstract
Techniques are described for generating predictions of future traffic conditions at multiple future times, such as by using probabilistic techniques to assess various input data while repeatedly producing future time series predictions for each of numerous 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 future traffic condition predictions for each geographic area of interest, such as based on observed historical traffic conditions for those geographic areas. Predicted future traffic condition information may then 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 future times.
