Field Evaluation of the Smartphone-based Travel Behaviour Data Collection App “SmartMo”

This paper outlines an innovative approach to the evaluation of a self-administered smartphone-based survey for the collection of travel behaviour data. For this approach, a traditional travel survey is modified to match mobile devices. The smartphone application “SmartMo” is designed in a multi-stage iterative development process. It is then implemented and evaluated through a number of field tests involving 97 participants. Results of the field evaluation will be discussed including the technical performance (e.g. secure data transfer and data management, energy consumption, map-matching), usability (e.g. comprehensibility, handling, joy of use) as well as user acceptance (e.g. willingness to participate, data protection and privacy). A brief overview of the SmartMo data collection system will also be provided.
