How European Travelers Make Decisions Regarding Airport Access Mode Choice

Different socio-economic characteristics and factors related to transport system influence travellers’ behaviour regarding transport mode choice for the travel to/from the airport. In this paper, characteristics that influence travel mode pattern in multimodal door-to-door service, with air transport mode as a main leg, are analysed. The Decision Tree (DT) models are built, based on the data obtained from the survey, conducted as a part of the SYN+AIR project. Datasets, derived from the answers of the respondents from Italy, Spain, Greece, and Serbia are analysed separately. The results highlight the travellers’ attitude and importance of factors that influence their travel mode choice, and show that travellers from different countries differently valued proposed factors. The reliability of the transport was often chosen as the most important factor by the respondents (regardless their country of origin). However, the proposed model showed that different factors for different markets also influenced travel mode choice. Obtained results confirm heterogeneity in different European air transport markets. Moreover, it is highlighted that different aspects of future service should be prioritized in order to implement a new multimodal door-to-door service.
