私家车越来越多，城市交通的压力越来越大，天天堵车。为了有效治理交通拥堵，国内一些大城市今年很可能会制定交通拥堵费政策。请用英语写一篇英语作文，描述糟糕的交通情况，并提出你的治理建议。
How horrible the traffic is! The picture depicts a scenario of a terrible traffic jam in the street. In fact, the traffic jam is so heavy that it is more of a parking lot than a crowded street. Anxious passengers cannot take buses because there are few buses. Instead, the street is filled with too many private cars.
Exaggerated as it is, the phenomenon is not uncommon nowadays. With the number of private cars increasing, traffic jams in metropolitans are bound to happen. Heavy transportation pressure in large cities may bring much inconvenience to people and exert negative impacts on the environment. On the one hand, when traffic jam happens, short distance in the past now seems to become terribly long, and drivers could do nothing but to wait. Therefore, a lot of precious time has been wasted on the road. On the other hand, exhausted gas emitted by cars has increased the burden of environment and caused carbon emission, which has diverted from the concept of living a low carbon life.
Therefore, effective measures should be taken to alleviate the traffic jam. Firstly, taxes levied on the sales of private cars should be raised so as to restrict private car ownership rate. Secondly, public transportation such as buses and subways, which are low-carbon transportation means, should be encouraged and promoted so that we can have a smooth transportation.
