Accessibility, the ease with which one can travel from one location to another, is a key topic at the intersection of urban and transport geography and plays an important role in our everyday lives. This doctoral research project aims to develop an innovative framework that integrates multiple air transport dimensions into a coherent accessibility analysis on the European scale. The project focuses on travel time and travel cost as main indicators of accessibility. The combined effects on accessibility of the following dimensions will be evaluated: (1) the principle of self-hubbing, i.e. passengers combining multiple flight tickets themselves to reach their destination, (2) multimodal transport, i.e. using a combination of transport modes, and (3) the concept of an airport catchment area, i.e. the area from which an airport resources passengers. To this end we will adopt innovative approaches to the data collection process, e.g. by focusing on web data and by automating the process using programming code. To the best of our knowledge, no study has yet been undertaken that integrates all of these dimensions above in a single, coherent accessibility analysis of the European urban landscape.
