Hong Kong International Airport (HKIA) is not only an infrastructure for transporting air passengers to and from worldwide destinations. It also equipped with a variety of services/facilities to give air passengers an enriching experience when passing through it. Air passenger traffic at HKIA is experiencing ever-increasing levels of demand due to a variety of influences, such as worldwide economic growth and the strong focus on the development of Hong Kong's tourist industry. The traffic expansion has lead to demand overload on both airport ground access transport system and airport terminal facilities. To deal with this overload, improvements to the existing passenger terminal facilities and the means whereby prospective air passengers access the airport are essential. This necessitates an up-to-date understanding of passenger behaviors and needs.;This research study makes four contributions to existing transport research knowledge, the first is an assessment of the safety margin allowed by departing air passengers for ground access to HKIA. The second contribution of this research is the calibration of discrete choice models for understanding departing air passenger ground access mode choice behavior in order to improve the HKIA access mode services in the short-term horizon. The effects of safety margins, travel time reliability and passenger satisfaction on mode utility are explicitly considered in the discrete choice models.;The development of a new set of level-of-service (LOS) standards for passenger orientation within the airport passenger terminals is the third contribution of this research. The proposed LOS standards can be used as criteria for the design and improvement of airport passenger terminal layouts and wayfinding aids. The fourth contribution of this research is the assessment of departing and transfer/transit air passenger perceived importance and satisfaction on the service items provided within the HKIA passenger terminal, and suggesting the items that need improvements.;It is believed that the findings of this research can provide practical contributions for a future higher satisfaction regarding the overall performance of HKIA. It also provides a starting point for developing a much grand model to relate the demand for airport ground access modes and airport terminal facilities.
