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

Word-of-mouth (WOM) and intention to continue use (ICU) are the two critical components of customer loyalty towards a particular service. There has been a large body of research investigating the effect of determinants on the loyalty formation of public transport passengers. However, the impact of social cues from other passengers, which are part of the social environment, have received less attention. This study developed a theoretical model to examine the complex relationships among the cues from other passengers, perceived security and safety, perceived value, WOM and ICU. Cues from other passengers involved three dimensions: similarity, physical appearance, and suitable behaviour. These three dimensions were measured using a formative approach in structural equation modelling (SEM). Additionally, the moderating effects of demographic characteristics on the formation of public transport passenger behaviours were explored by multi-group SEM. The model was empirically tested using data collected from more than 870 bus passengers in two big cities in Vietnam (Ho Chi Minh and Danang city). The results showed that social cues from other passengers have a strong predictive power over the WOM and ICU of bus passengers. The study successfully demonstrated the critical role of demographic characteristics as moderators on loyalty formation. The findings reported in the present investigation provide several theoretical and practical implications.@en
