Michael Shell, an economist at the United States Environmental Protection Agency (OTC) Office of Transportation and Air Quality, attended and spoke at the Awareness Week seminar on April 26th. The quality of the air is organized by the US Embassy.
According to Shell, the use of many engines, rather than public transport, is one of the main reasons for traffic congestion and ongoing air pollution. US experts also mentioned that in Vietnam there are some suggestions to ban engines to reduce traffic congestion and improve air quality.
Mr Shell estimated that the reason why motor vehicles are used so much in Vietnam is because it's a simple, fast and easy way to work. According to him, in fact, driving on a motorcycle is more efficient in terms of space, because if at the same time all drivers turn to cars, the surface of the used road surface will be much larger. .
US experts ask the question: If the ban on seeing the device, what kind of means will people use?
According to Mr. Shell, in the case of Vietnam, people tend to use more cars. Mr Shell cites statistics showing that between 1,000 people in Vietnam, only 23 have cars, while in the United States, 1,000 people will have 790 vehicles. However, this figure in Vietnam is expected to increase in the future.
"Vietnam's economy is growing rapidly, growing by 7% a year, people's lives are rising, leading to more shopping needs. The desire of people to buy more cars will create more pressure on the environment," Schell said.
US experts say that the problem posed by Vietnam, like other developing countries, is how to ensure economic growth and protection of the environment and to ensure people's health. .
Mr Shell mentioned the "three-legged" strategy to address the current use of transport.
First pillar: Fuel purifier. Accordingly, vehicles can use environmentally friendly fuel during combustion, which reduces CO2 emissions.
Second column: New technology. Accordingly, vehicles will use engines with efficient fuel consumption. In the United States, the country has raised the standard for motor vehicles and requires every vehicle to travel on the road to meet CO2 emissions requirements.
Third pillar: Behavior of traffic participants. In order to change behavior, the most effective way is to encourage good behavior by making it easier to implement, while at the same time restricting bad behavior by making it more difficult and costly.
According to Shell's expert, in order for Vietnamese to change the behavior of regular motorcycles when participating in traffic, there should be public vehicles with reasonable prices and convenient transportation, such as ships. underground or buses like major cities in the world are still under way.
"If you offer a simpler, easier, more economical travel plan, people will choose that option. This not only improves the economy, but also improves air quality," said Shell.
Mr. Shell took the evidence in Washington after building a private and convenient road for bicycles, many people chose this travel vehicle. The number of people using bicycles in Washington is the highest among other US cities and states.
US experts also mentioned the solution that many cities around the world have applied, which means making more expensive than unwanted behavior.
In the capital, London, England, the government has predicted that vehicles entering the central area must be high-tech assets, which will limit CO2 emissions, unless they pay very expensive. Stockholm, Sweden, also applies this rule.
In the meantime, in New York, the United States faces traffic congestion in some areas, especially those with high traffic density in hours. New York is the only city in the United States to apply traffic jams. Accordingly, vehicles entering this area will have to pay high fees (11 USD). The purpose of this measure is to discourage people from traveling to the city during traffic jams instead of using public transport.
Paris, France also has problems with air quality with many vehicles. Similarly to some countries such as Colombia, Mexico, Paris, even sea and sea-sea methods, which rely on sea numbers, also apply to allow vehicles to enter the city on even strange days. However, this is only a short-term measure, because without a comprehensive solution, it is likely that people will buy two or three new cars to have even a sea and a strange sea due to high demand.
US experts stressed that apart from restricting private vehicles, Vietnam should intensify the construction of public transportation networks to provide people's needs.
