The group behavior of the vehicle, which can accurately describe the movement law of the vehicle in the vehicle network. In the vehicle network, the vehicle with strong GPS signal can utilize its communication ability and its neighbor position relationship, which can be located within a certain distance. Real-time location calculations for vehicles with the same or similar destinations and weak GPS signals. The method first proposed a tag cluster partitioning algorithm for vehicle destination companion tags. It would classify vehicles with the same or similar destinations as their tags, mining the tag overlap structure, and mining the hierarchy to divide them. To the same tag cluster, they were clustered into an independent vehicle group. Then, this paper proposed a positioning algorithm based on the results of label partitioning, and a result correction algorithm to calculate the real-time position of the vehicle waiting for positioning. The experimental results show that compared with the similar method, the positioning error is reduced by 15%~35%. Under different traffic conditions, the stability of the result is improved by more than 25%. Therefore, the proposed positioning method is effective.
