Abstract

A method of identifying information during navigation is provided. Fork data is extracted from navigation data, the fork data corresponding to a road having a fork. A first node and at least two exit roads are extracted from the fork data, the at least two exit roads being roads in different directions. The fork data are identified as corresponding to a target fork in response to all of the at least two exit roads converging at the first node. A second node adjacent to the first node is queried in response to at least two exit roads not completely converging at the first node. The fork data are identified as corresponding to the target fork based on a distance between the first node and the second node meeting a preset condition.
