Abstract: Aiming at matching the high sampled GNSS trajectory data with complex urban road networks, a matching method based on path increment is proposed. The method consists of two parts:combined filtering and incremental matching. Firstly, the road network is simplified through combined filtering, and then the matching process is carried out with the road paths as the increments. During the matching process at the intersection point, the similarity evaluation scheme integrating distance factor and curvature is adopted. In order to verify the effectiveness of the method, several high sampled trajectory data with different complexity are selected for experiments. The method is compared with two existing matching methods, including the curvedness feature constrained map matching method and hidden Markov model (HMM). The results show that the proposed method not only performs better in accuracy and efficiency, but also can suppress the occurrence of matching errors in various complex sections.
