The statistics of residents' travel is a very important basic data in traffic planning. Traditional resident trip survey usually uses the methods household survey and roadside monitoring which is time-consuming acquiring process, expensive and low-level automaticity. The method of calculating OD traffic capacity through the traffic volumes of road sections is studied in the preceding years, but it is difficult in parametric inference and algorithm solution, and its accuracy yet to be improved. With the development of mobile communication technology, the method of positioning based on GSM mobile phone network has attracted much attention in the application of traffic area. This paper introduces the mobile positioning technology, and uses the residents' mobile phone location and timestamps date, combined with the technology of map matching, adopting holistic approach and collecting idea, to analysis the OD trips between traffic cells. We use the mobile phone location data provided by the operator in China to confirm this method.
