Abstract/Summary This paper puts forward a method to automatically detect trips/trip-segments based on the instantaneous movement attributes of individuals that can be collected automatically by smartphone sensors. The goal is to enhance the accuracy of collected data by better identifying single mode trips/trip-segments, while minimizing participant’s involvement and preserving battery life. The proposed method works independent of external databases and can be implemented in smartphone applications to enhance the accuracy of collected data and minimize the required data transfer. The method consists of a combination of real time and post processing and incorporates a series of rules to clean, split and merge trips/trip-segments in required. The performance of the model has been evaluated in a real-world experiment, where it achieves an overall accuracy of 97% in detecting trips from records of daily tracks. The analysis of the results shows that the implementation of the trip detection model increases the number of detected non-motorized trips by 6%. In addition, the implementation of the model increased data accuracy, in terms of the duration and length of recorded trips.
