Abstract Inferring context information from periods of transportation is an important subtopic of the wider field of mobile and ubiquitous sensing. The transportation behavior reveals information about individual’s physical activity, preferred transit types, mobility patterns and important places. As a platform for mobile sensing, we employ common smartphones, which have matured into a quintessential instrument with both new challenges and new possibilities. The presented research contributes by addressing several key constraints of smartphone based context sensing, including determining the phone’s orientation in real-time, introducing energy-efficient sensor management, and advanced feature engineering from accelerometer.
