摘 要：This study analyzed the potential of cell phone positioning techniques in freight trucks data collection and long-haul truckshed (geographic extent) tracking. The freight truck identification and tracking algorithms were developed by means of cell phone network data and the established freight truck analysis GIS to recognize the freight trucks and determine their geographic extent (trucksheds). A case study was conducted to illustrate the truckshed tracking process and verify the tracking result from the cell phone network.
