Transport sustainability has become a major challenge worldwide. On-demand shared ride-hailing (OSR) is an alternative transport mode to private motorized mobility which allows passengers to share a vehicle and driver to their respective destination. OSR is more flexible than buses and cheaper than taxis. Additionally, ride-hailing services such as OSR play an important role in servicing communities with poor access to public transport (e.g., buses or trains) and people with increased vulnerabilities (e.g., women with children or people with disabilities). The present study investigates the impact of psychological factors on passengers' intention to use OSR services. To achieve this, the Theory of Planned Behaviour (TPB) was used and extended with perceived risk, price sensitivity, and perceived green value. Data were collected from 520 ride-hailing passengers in Vietnam. The results confirm the relevance of the original TPB constructs, i.e., attitudes, perceived behavioural control, and social norms. Concerning the three additional constructs, only perceived risk negatively and directly influences usage intention, while the two other constructs (i.e., price sensitivity and perceived green value) influence the intention to use OSR via attitudes. The results also reveal that the impact of perceived green value on usage intention is higher among females than males. Additionally, among middle- and high-income people, there is a significant negative association between perceived risk and intention, while this association is not significant among low-income participants. The findings from the present paper provide evidence of the importance of psychosocial factors such as perceptions of risk, price sensitivity, and sustainability when considering intention to use on-demand shared transport services.@en

The present study quantitatively investigates the influence of booking app-related risk and vehicle & driver-related risk on ride-sourcing passengers’ trust, satisfaction and loyalty. A conceptual model was developed and tested with data collected from 545 ride-sourcing users in Ho Chi Minh City, Vietnam. The findings indicated that perceived vehicle & driver-related risk directly affected passengers’ satisfaction and loyalty significantly. At the same time, trust mediated the relationships between perceived booking app-related risks and satisfaction and loyalty. These findings enable practitioners and policymakers to better prioritise risk dimensions when developing strategies to increase passengers’ trust, satisfaction and loyalty. Finally, the insights provided in this investigation can be used as a guide for ride-sourcing companies to improve risk manangement and risk communication efforts to increase patronage.@en

Ride-hailing services are increasingly consolidating their role in the transport sector in low- and middle-income countries where there is limited investment in public transport. However, much is unknown about the determinants of ride-hailing service use and quality of the service. The present study investigates the direct and indirect influences of perceived quality of ride-hailing service including perceived booking app and perceived post-booking service quality on continuous usage intention and word-of-mouth (WOM) of ride-hailing passengers. Emerging research has aimed to understand the hierarchical structure of ride-hailing service quality (including booking app and post-booking service). Therefore, this study proposes a formative hierarchical component model of perceived booking app quality consisting of seven dimensions (i.e., privacy and security, ease of use, functionality, design, information accuracy, route detection, and service). Likewise, the perceived post-booking service quality is comprised of four dimensions (i.e., reliability, personal, convenience, and tangibility). Data used for testing the model was collected from 536 ride-hailing service users in Ho Chi Minh city, Vietnam. The results provide insights into attributes forming perceived quality of ride-hailing booking apps and perceived post-booking service quality and how these constructs affect passenger loyalty. The results are also useful for ride-hailing companies in their efforts to prioritise critical service attributes and ensure their service quality meets or exceeds passengers’ expectations.@en
