In this paper, handover location technique is employed for positioning mobile probes. In view of low location accuracy of handover location technique, an outlier handover location correction approach was presented that solved the problem in two phases, travel speed correction of outlier handover link and outlier handover location reposition. In the first phase, a two-layer data fusion model based on the definition of bridge handover link was proposed for recalculating the travel speeds of outlier handover links. In the second phase, the problem of outlier handover location reposition was solved by genetic algorithm. Based on the empirical data, absolute errors of travel speeds of handover links determined by the corrected results are analyzed and compared with results without outlier handover location correction. Evaluation results demonstrate that the proposed approach is feasible and effective, which can be used in the application of traffic information extraction.
