1. A method, implemented on one or more processors, for defining road segment boundaries comprising:
receiving, by the one or more processors, a plurality of road segments with each road segment including an associated set of boundaries; receiving and logging, by the one or more processors, from a plurality of devices traversing road segments, information comprising a segment identifier and information related to speed of traversal by the devices; selecting, by the one or more processor, at least one road segment based on a frequency of the at least one road segment being traversed; and adjusting, by the one or more processors, the set of boundaries of the at least one selected road segment based on the information related to speed of traversal by the devices, wherein the adjusting of the set of boundaries comprises combining at least two adjacent road segments based on (1) deviation of travel times or average speeds of each of the two adjacent road segments from an average of the travel times or the average speeds of the two adjacent road segments, and (2) the frequency of at least one of the at least two adjacent road segments being traversed, said combining the at least two adjacent road segments including maintaining segment identifiers associated with the at least two adjacent road segments. |
