Learning road navigation paths based on aggregate driver behavior

摘要

Techniques are described for generating and using information regarding road traffic in various ways, including by obtaining and analyzing road traffic information regarding actual behavior of drivers of vehicles on a network of roads. Obtained actual driver behavior information may in some situations be analyzed to identify decision point locations at which drivers face choices corresponding to possible alternative routes through the network of roads (e.g., intersections, highway exits and/or entrances, etc.), as well as to track the actual use by drivers of particular paths between particular decision points in order to determine preferred compound links between those decision point locations. The identified and determined information from the analysis may then be used in various manners, including in some situations to assist in determining particular recommended or preferred routes of vehicles through the network of roads based at least in part on actual driver behavior information.

主权项

1. A computer-implemented method comprising:
receiving, by one or more configured computing systems, information that is gathered by a plurality of devices in a plurality of vehicles traveling on one or more roads and that reflects actual prior driver behavior during a plurality of prior vehicle trips along the one or more roads by the plurality of vehicles, wherein the actual prior driver behavior during the prior vehicle trips includes driver selections between multiple alternative choices at decision points along the one or more roads; automatically analyzing, by the one or more configured computing systems and for multiple alternative paths between two locations on the one or more roads, the received information to determine a compound link representing a preferred path of the multiple alternative paths based at least in part on use of the preferred path from the actual prior driver behavior during the plurality of prior vehicle trips, wherein the automatic analyzing includes using values of an indicated traffic measure for the multiple alternative paths that are assessed from the received information; and providing, by the one or more configured computing systems, an indication of the determined compound link, to enable future routine decisions using the determined compound link for vehicles on the one or more roads.
