The perceived usability of vehicle sharing mobile application: An integration of UTAUT, pro-environmental behavior, and system usability scale

Vehicle sharing is one of the most innovative ways to transport business and management. The purpose of this study was to determine factors affecting the perceived usability of vehicle-sharing mobile applications by integrating the Unified Theory of Acceptance and Use of Technology (UTAUT), pro-environmental behavior (PEB), and system usability scale (SUS). 206 Taiwanese filled out an online questionnaire with 65 questions which was shared using a convenience sampling approach. Partial Least Squares-Structural Equation showed that perceived usability was found to be significantly influenced by price value, environmental concern, authority support, behavioral intention, and actual use. Interestingly, authority support was found to have the highest significant indirect effect on perceived usability, indicating that vehicle-sharing mobile applications must be supported by the national government in order for people to consistently use them. This study is one of the first studies that analyzed vehicle sharing, particularly the mobile application. The findings of this study may be used as a guideline or strategy for the national government to reduce environmental risks caused by thousands of vehicles in the country, for vehicle-sharing companies to further boost their profit, and for other investors who intend on utilizing mobile applications for their market.
