With the continuous growth of the urban population, traffic congestion has become a major problem in all cities. Congestion charging is in practice an effective tool to solve this problem. In this paper, we use the classical model of Congestion Charging to study the issues of pricingcharges in Ho Chi Minh City. In order to capture the traffic flow, we adopt the Drake speed - density model, which relies on the relationship of speed, density and flow and is further conducted by monitoring the traffic flow. After collecting the base traffic data of Ho Chi Minh City, we analyzed the relationship among speed, density and flow. The result showes that, the model we use performance better in reflecting the actual situation in Ho Chi Minh City than other models. Finally, this paper also numerically shows how much should charge to achieve the expected speed. The corresponding traffic density and flow are given in these examples as well.
