What are the advantages and disadvantagesof banning private motor vehicles in city centres

City centers are always the “must-go” places for everyone to enjoy all its colorful and outstanding shops, commercial centers, and office buildings. This explains why those areas attract more and more people and simultaneously put themselves among the most troublesome concerns of the city governments. They tried hard to control the number of private motor vehicles going to the center of the city. This have advantages as well as disadvantages when it helps to lessen the pollution, reduce the traffic jam, and save spaces, but also brings inconveniences, and costs lots of time and investment.
There are three main advantages of private cars prohibition in the downtown. First, this obviously eases the pollution problem. There would be no more smoke from all kind of cars, no more terrible noises of horns and engines disturbing people all the time if there were no vehicles in the business center. However, it is so hard to reach that ideal situation then fewer cars or public transports only would also helps. Secondly, the daytime nightmare of all people: traffic jam will be reduced efficiently. This brightening result helps people to diminish stresses caused by staying still in the middle of the jam. In fact, you may save half of the time travelling home and have double time for relaxation as long as the street is clear. Furthermore, if it is forbidden for cars to enter the downtown, lots of spaces will be saved. Land which is used as car-park can be redesigned to be another office building or trade center and while land is money, this will bring a remarkable economic benefit.
In controversy, there are undeniable advantages of this policy which would lead to people's opjection. First of all, it may cause many inconveniences for the citizens. For those who come to the area to shopping, it is really uncomfortable when they have to manage bags full of goods in their hands hustling to the crowded public transports. That is not the end of the trouble, without their private motor vehicles, people have to spend more time using buses or trams or the underground to hit their destinations. In addition, the governments have to spend more money on developing the public transportation as well as parking lot in the suburb around the banned area.
The argument of this matter is still carried on since this policy brings both the positive and negative effects to the society. Whether pollution, street congestion and space amelioration are more important than inconveniences, time and budget trouble is, however, hard to see. Notwithstanding the undefined answer, city governments still do their best to have the number of private cars decreased.
