The one with traffic problem Today, the city traffic problem is getting worse, such as traffic jams, parking problems and the deficiency of the public transportation systems. With greater purchasing power, there are more and more people prefer to buy car. Being one of the main inventions, the car brings about great changes to our life. But when we enjoy the convenience that automobile bring to us, we are also perplexed for the traffic and environment. We are wasting our time on the road and inhaling automobile exhaust. In order to alleviate traffic pressure, like the Beijing's government has been implementing odd-even license plate policy, and in Guangzhou it has been limiting the license plate issued. Despite of this, the traffic is still bad. In rush-hour the road all of sudden become to the park lot. The government encourage people to use public transportation, but the situation is not so positive. Not only do you have to squeeze your way onto buses or subway, but you have to beware of many thieves. Currently, there are nine subway lines in Guangzhou and one shift every three minutes. In addition, nearly 1,000 bus lines and no less than 9,000 buses are serving citizens, but it seems to not enough. Do the government need to get more new buses? or build more new urban viaduct ? In my opinion,the main reason of city traffic problem is that the city is too big as well as the population is too huge, which means the people have to rely on the automobile and the public transportation systems to go where they want.So developing the third-and fourth-tier cities and encouraging people to live and work there maybe can solve the traffic problem.
