At present, traffic jam has become a major problem which most city dwellers, especially those who live in metropolis. Have to confront in their everyday lives. Why is traffic jam a problem ? At first ,owing to the fact that the vehicles keep giving off harmful gases during traffic jams ,air pollution and furthermore, global
warming will deteriorate. In addition, traffic jams will affect the effectiveness of work, because the people have to spend much more time on way to office than necessary, and their work will be distracted or delayed. Apart from this, traffic jam might give rise to more traffic accidents and therefore becomes a menace to people’s lives. So harmful traffic jam is, the number of private cars still goes up apace. Why? Personally I think, the first reason may be the remoteness of people’s workplace. As a result, people have to choose a tool other than walk to go to work. Being flexible and relatively convenient, private car becomes a very attractive choice .Moreover , owning a private car, especially in some developing countries, is itself a symbol of wealth and high social position. In some developed countries such as USA it is also the symbol of independence and maturity. Anyway ,owning and driving private cars are regarded by many people as basic human rights.
Undoubtedly, traffic jam must be ,and can be alleviated by correct means .In my view, spending more money on public transportation systems may be a feasible
means .Needless to say, policies which encourage people to put these systems to full use, for example, giving certain subsidies, are necessary. In the meantime, measures to restrict the use of private cars, such as levying higher taxes on cars or petrol, its fuel, or exerting more restrictions on the distribution of certificate, should be taken.
