| Abstract: | Identifying movement process of mobile stations exactly is the base of applying wireless location technology to collect traffic(information.)Based on the analysis of movement character of mobile stations,this paper expounds its principium of identifying movement process of mobile stations.Labeling algorithm is used to implement the move-or-stay identification of GPS equipment according to the GPS data obtained by factual test,and different results are obtained under different time intervals of sampling.The experiment results show that if time interval of sampling is proper,labeling algorithm can obtain favorable results of identification. |
