Efficient Smartphone Sensor Analysis for Behavioral Profiling in Transportation

This study investigates smartphone sensor data for classifying drivers and passengers, aligning with the research team's original proposal to enhance multimodal transportation data collection via the OneBusAway app. The research team addresses challenges in balancing data quality with smartphone resource constraints and find that shorter data collection windows significantly improve classification performance. Additionally, feature standardization and selection enhance accuracy, particularly during extended data periods, supporting the goal of refining data quality from open-source platforms. These insights advance the objectives by optimizing data efficiency and supporting the real-world applicability of intelligent models in transportation safety and efficiency.
