This paper summarizes the findings from the workshop "Surveys on long-distance travel and other rare events". The main objectives for this workshop were to discuss suitable definitions for long-distance passenger travel as well as to exchange knowledge and ideas about available and potential data sources, methods for data collection, and emerging research questions. Various interesting topics were identified for future research on long-distance travel. These include the combination of complementary and innovative data sources, new survey techniques, and addressing hindrances to survey participation. Strengthened interdisciplinary research is expected to reveal new valuable insight.
