| Abstract(in English) | Determining the mode of transportation of an individual is one of important elements of contextual information for understanding human behavior. In particular, we focus on distinguishing different types of motorized transport such as train, bus, and subway. Moreover, we also classify a specific name of line of the transport type which a user rode on. Our approach uses location histories of an individual from its Call Detail Records (CDRs) and GIS information of routes for public transportation published by the Ministry of Land, Infrastructure, Transport and Tourism of Japan. Instead of referring to GPS-enabled location histories, we resort to more energy efficient sensing resources, such like a series of cell tower signals from CDRs. As a key contribution of this work, we proposed an automated method to generate an alignment of cell towers for a specific transportation route using unsupervised machine learning techniques. By utilizing CDRs which have been stored for a running operation of mobile networks, we succeeded to accurately detect a mode of transportation without consuming extra energy for its purpose on a mobile phone. |
