Reducing traffic congestion and restricting the use of private motorized vehicles are the goal of many major cities around the world. Therefore, there have been many studies to provide solutions to the issue of urban traffic congestion. Traffic congestion charge like Electronic Road Pricing (ERP) for traffic to entry downtown is one of the measures that has been successfully applied in some cities such as London, Stockholm, Singapore and others. This measure is also mentioned by Vietnamese experts. However, up to now, although there have been a few studies on this issue, the proposed solutions have not been applied. One of the reasons that may be the impact assessment of the congestion charge solutions is not enough convincing. This study introduces a method of assessing the impact of congestion charge using the VISUM traffic simulation tool. A set of indicators quantified is used in this study to assess the impact of congestion charge. The assessing results show some aspect of the future picture when the congestion charge is applied in Ho Chi Minh City (HCMC) downtown and will be helpful for HCMC in formulating congestion charge solutions by choosing among scenarios of charge level.
