1. 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.
