  • The fundamental units for the measurement of the level of service (LOS) at airport terminals are per passenger space and waiting time. The IATA framework measures passenger density and waiting time separately, which could lead to conflicting measurements when passenger density and waiting time indicates different LOS levels. 

    This thesis is therefore aimed to develop a combined spatial and temporal LOS (ST-LOS) framework to guide terminal planning. 

    The first stage 

    In the first stage of this thesis, a passenger survey was conducted, which involved the Repertory Grid Technique (RGT), a questionnaire, an experiment and a semi-structured interview. Results showed that two-thirds of the participants perceived a decreased service quality associated with crowdedness at airports, and 85 per cent of the RGT constructs indicated dissatisfaction regarding space.  

    47 per cent of the senior Australian participants previously complained about inter-person-spacing (IPS) at airports, while none of the senior Korean participants did so. The young Australian participants were tolerant of smaller personal space, 15cm smaller IPS on average, compared to the senior Australian participants.  

    These findings revealed a moderating role of age and cultural background in the personal space demand of passengers and suggested the necessity of an alternative LOS standard that incorporates the concept of perceived personal space as a spatial LOS attribute.  

    The second stage 

    In the second stage, computer simulation was used to test the proposed ST-LOS framework under different terminal and passenger settings. The ST-LOS was built by combining the temporal and spatial measurements and aimed to allow at least 50 per cent of passengers to experience the optimum LOS.  

    In the base simulation, 65 per cent of passengers experienced the optimum LOS according to the ST-LOS. However, only 22 per cent of passengers experienced the optimum LOS defined by the current IATA standard. To meet the IATA standard, the check-in queue width had to be reduced from 1.5m to 1.2m that differed from the recommended queue width (1.4m-1.6m) by IATA.  

    A case study based on Sydney International Airport illustrated the application of the ST-LOS framework for LOS measurement. The case study revealed that our ST-LOS framework better represents the LOS that passengers will experience, and that incorporating personal space demand of passengers will improve the LOS standard.

  • An increased use of automation within the air traffic management environment is seen to be one possible enabler for a significant capacity increase of the air traffic management system.  

    However, often automated tools and systems are rejected by the air traffic controller's unwillingness to cooperate with it. This research defines the threshold along the automation dimensions ‘decision selection’ and ‘action implementation’, where the support of the operators tips into skepticism and refusal to collaborate with it.
