Traffic congestion pricing is an economic tool widely used in big cities to manage urban traffic and reduce pollution. In Hanoi, rapid urbanization and increasing private vehicle ownership have exacerbated congestion issues. This study investigates road users' willingness-to-pay (WTP) and key factors influencing public acceptability of congestion pricing. Results from a stated preference (SP) survey show that 73.2% support congestion pricing, among which 29.5% will support under specific conditions. Key influencing factors include public transport quality and connectivity, transparent revenues usage, convenient payment systems, and reasonable toll rates. The average WTP for private vehicle users is 30,000 VND per trip, with higher acceptance among those with greater financial flexibility. However, concerns remain regarding a potential shift to motorcycles if congestion pricing is implemented without public transport improvements. These findings could provide useful recommendation to Hanoi's authorities as well as other similar cities in developing an effective congestion pricing program.
