The invention discloses an improved interactive voting map route matching method for a low-frequency GPS trajectory, which not only considers a distance feature, a topologic structure of a road and alimit speed of a road section, but also considers a real-time moving direction and speed of each GPS point, so that the matching accuracy can be improved; in addition, a filter is added, a candidate noise road section is removed by virtue of a constraint condition, so that the matching efficiency is improved. The improved interactive voting matching method for the low-frequency GPS trajectory hasthe advantages of high matching accuracy, high efficiency and high robustness.
