Abstract
In this study, a mobile application-based service providing information on the reduction in the air pollution source emissions due to the replacement of conventional scooters by electric scooters (e-scooters) was proposed to increase user awareness of air quality and purchase intention towards e-scooters. The extended unified theory of acceptance and use of technology was employed and an explanatory variable of environmental awareness (EA) was incorporated for enhancing constructs to investigate the factors that may influence the user acceptance of text-based mobile information on the reduced carbon emissions, in comparison with that of histogram-based mobile information on the reduction in emissions of six air pollution sources. A within-subjects experimental design was employed to evaluate both information contents. The results indicate that the model constructs of habit and EA are useful predictors of the behavioural intention (BI) to use app services. Furthermore, providing different mobile information contents demonstrated no statistically significant difference in the user’s acceptance and intentions. However, providing different mobile information contents on the same information spindle may trigger different constructs and intensities of influence on users’ purchase intentions for e-scooters. Based on these findings, several recommendations for app managers and developers and suggestions for future research have been provided.
Highlights
Air quality is closely linked to the Earth’s climate and ecosystems globally
The contribution of this research is that the model constructs of HA and environmental awareness (EA) are useful predictors of the behavioural intention to use the app service
The results of this study indicate that providing different mobile information contents on the same information spindle may not have a significant difference in the impact on the user acceptance and intention and may trigger different constructs and intensities of influence on user acceptance and intention
Summary
Air quality is closely linked to the Earth’s climate and ecosystems globally. ambient air pollution is expected to potentially impact the global market, thereby leading to significant economic and healthcare costs in the few decades [1]. To reduce the air pollution caused by fuel-powered scooters, the Taiwanese government has implemented a policy of purchase/replacement subsidy to encourage people to replace two-stroke/fourstroke scooters with electric two-wheelers (E2Ws) or cleaner scooters that meet the Phase-7 emission standards. Because providing E2W test ride services has a positive impact on the user acceptance level of the E2W product, many E2W manufacturers have launched free test ride services to promote their E2W products for Taiwanese consumers. The purpose of this study is to experimentally explore user acceptance using an app service, which contains information regarding the reduction in air pollution source emissions resulting from the replacement of conventional scooters with e-scooters, and understand the effect of the environmental information on user evaluation of the quality of their interaction with the app. This study aims to analyse the user experience in receiving environmental information on an app, to understand the Promet – Traffic&Transportation, Vol 34, 2022, No 1, 53-67
