Abstract
An efficient map matching method for GPS trajectory includes: obtaining a valid GPS point list; obtaining a current searched end point; backtracking a best map matching path from the current searched end point, traversing GPS points along the path to obtain best matching results, and summarizing the best matching results to output a matching result statistical table; and determining whether the current searched end point is a final point.
