Abstract:This research project analyzes freight transportation data and enhances the regional freight transportation model to better estimate and forecast truck travel in the Philadelphia region. In particular, this project infers truck activity from global positioning system (GPS) traces data (acquired by Delaware Valley Regional Planning Commission). Identifying truck activity in this case refers to identifying stops made by the truck, identifying hubs of operations (if they exist), and identifying tours and trips made by the truck. In an effort to achieve the above stated goal, two additional sub-activities were undertaken. First, developing device matching/chaining methods to deal with the issue of several device identifiers resetting at midnight. Second, developing clustering methods for stops to remove false positive stops and infer hubs of operations. Finally, files containing the device/truck activity information were created.
