Development and Validation of a Vertiport Usability Scale
Main Article Content
Abstract
Introduction: Urban Air Mobility (UAM), a distinct subset of Advanced Air Mobility (AAM) research, has begun reaching a critical phase in its establishment, particularly with the development and implementation of vertiports. Few studies have assessed consumer perception of vertiports. One particular study focuses on the ideal usage and applicability of vertiports for medical emergencies; however, this current study aims to broaden that perspective by producing a valid scale that other researchers can use. Method: The Vertiport Usability Scale was developed using a multi-stage approach with 1,243 participants. A consensus methodology was employed, whereby participants generated relevant descriptive items, determined which items were most relevant, and provided construct validity to the final scale. Results: The final scale resulted in a single-factor model comprising seven items (convenient, efficient, functional, good location, high quality, usable, and useful). Factor analysis was used to ensure validity, while Cronbach’s Alpha and Guttman’s split-half tests provided evidence of high consistency and reliability. Conclusion: This scale offers a common language for consumers, designers, engineers, and human factors experts to design future vertiports in line with consumer opinions and needs.
