The GPS shifting fields can be revised with a road segment attribute and/or at a driver preference. The road map network can be partitioned into space units, where the road map network can include at least two GPS readings of the object. For each space unit that includes a road segment, a probability that the object was located on the road segment can be calculated for each road segment based on the GPS readings of the object and the GPS shifting fields. The trajectory of the object can be determined based on the computing of the probabilities."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"GPS map-matching based on space map-matching","description":"An embodiment of the invention provides a method that identifies GPS shifting fields for road segments, the GPS shifting fields including areas around the road segments that include false GPS readings","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9835460","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
