This study is aimed at analyzing and evaluating the current status of the quality of public transport in Vinh Long province – one of the emerging provinces in the Mekong River Delta (MRD) Vietnam. The research employed the data set of direct interviews with 140 respondents who have and have not to experience in using public transport for analysis and comparison purposes. The contribution of this research is comparing the opinions of current and potential users of public transport and employing the conventional CVM approach and inferred valuation (IV) to compare the fees people are willing to contribute to current public transport improvement projects. The research results revealed that the current state of the transport system has not met the needs of users. The research results also clearly indicate the role of the IV estimation method in adjusting the WTP value elicited closer to reality. The interesting point is that people who have never used public transport are willing to pay more for better quality. In addition, respondents' gender and income influence this willingness to pay for both groups of observations. Based on the analysis results, the study proposes a number of solutions to stakeholders such as the government, public transport companies, and people to promote the development of public transport in the near future.
