The apparatus can have a map matching system that can include a link selector that is configured to select candidate links in the map based on a previous matched position and a path length threshold, and a matching processor that is configured to determine a matched link in the candidate links based on an equivalent distance from an estimated position to a link in the candidate links and determine a current matched position on the matched link. In an embodiment, the map matching system can further include an initializer that is configured to determine a matched position based on an equivalent distance from a first estimated position to an initial candidate link in the map."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for map matching","description":"Aspects of the disclosure provide an apparatus for determining a matched position of a mobile device in a map.
