Abstract
A method of generating map data indicating a deviation from expected jam conditions on a segment of a plurality of segments in an area covered by an electronic map, the segment having associated therewith a jam probability indicating the likelihood of a jam on that segment. The method comprises establishing an expected jam condition for the segment based on the jam probability of that segment, and then obtaining live data indicating the jam conditions on at least one of the plurality of other segments in the area. A revised jam condition can then be established for the segment using the obtained live data.

A method for generating map data including a jam condition for a segment from among a plurality of segments in an area covered by an electronic map, the segment having associated therewith a jam probability indicating a likelihood of a traffic jam on the segment, the method comprising:
- determining an expected jam condition for the segment based on the jam probability of the segment;
- obtaining live data indicating a respective jam condition for at least one other segment among the plurality of segments, the live data including travel times and supporting data for the at least one other segment, the supporting data including information about conditions affecting traffic on the at least one other segment;
- determining the live data is inconsistent with the expected jam condition;
- in response to determining the live data is inconsistent with the expected jam condition, acquiring additional live data and determining a revised jam condition for the segment based at least in part on the additional live data, the determining of the revised jam condition including weighting the supporting data relative to the travel times, the weighting based on whether the supporting data meets at least one supporting data condition;
- generating, based at least in part on the revised jam condition for the segment, a navigation route for guiding a user during navigation;
- and
- presenting, to the user, information about the at least one navigation route.
A system that generates map data including a jam condition for a segment from among a plurality of segments in an area covered by an electronic map, the segment having associated therewith a jam probability indicating a likelihood of a traffic jam on the segment, the system comprising:
- at least one processor, the at least one processor configured to:
- determine an expected jam condition for the segment based on the jam probability of the segment;
- obtain live data indicating a respective jam condition for at least one other segment among the plurality of segments, the live data including travel times and supporting data for the at least one other segment, the supporting data including information about conditions affecting traffic on the at least one other segment;
- determine the live data is inconsistent with the expected jam condition;
- in response to the determination that the live data is inconsistent with the expected jam condition, acquire additional live data and determine a revised jam condition for the segment based at least in part on the additional live data, the determining of the revised jam condition including weighting the supporting data relative to the travel times, the weighting based on whether the supporting data meets at least one supporting data condition;
- generate, based at least in part on the revised jam condition for the segment, a navigation route for guiding a user during navigation;
- and
- present, to the user, information identifying the at least one navigation route.
A non-transitory computer readable storage medium storing instructions that, when executed by at least one processor, cause the at least one processor to perform a method for generating map data including a jam condition for a segment from among a plurality of segments in an area covered by an electronic map, the segment having associated therewith a jam probability indicating a likelihood of a traffic jam on the segment, and the method comprising:
- determining an expected jam condition for the segment based on the jam probability of the segment;
- obtaining live data indicating a respective jam condition for at least one other segment among the plurality of segments, the live data including travel times and supporting data for the at least one other segment, the supporting data including information about conditions affecting traffic on the at least one other segment;
- determining the live data is inconsistent with the expected jam condition;
- in response to determining the live data is inconsistent with the expected jam condition, acquiring additional live data and determining a revised jam condition for the segment based at least in part on the additional live data, the determining of the revised jam condition including weighting the supporting data relative to the travel times, the weighting based on whether the supporting data meets at least one supporting data condition;
- generating, based at least in part on the revised jam condition for the segment, a navigation route for guiding a user during navigation;
- and
- presenting, to the user, information about the at least one navigation route.
