One of the most notable changes was the rapid proliferation of automobiles. The number of cars in Vietnam has increased tenfold in the past 10 years, and is expected to continue to increase in the coming years. This has led to increasingly severe traffic congestion in major cities.

Another change is the development of the public transport system. The Vietnamese government has invested in building new bus lines and metro systems. However, the public transport system has not yet met the needs of the people, and many people still have to travel by motorbike.

Traffic situation in Vietnam is a big problem that needs to be solved. The Vietnamese government is implementing a number of solutions to improve traffic conditions, including:

* Invest in building more roads and public transport systems.

* Strengthen propaganda on the sense of obeying traffic laws.

* Strengthen handling of traffic violations.

These solutions will help improve the traffic situation in Vietnam, and create a better living and working environment for the people.
