为解决交通, 有人建议多造马路, 有人建议限制自行车,和汽车, 你的看法?

　　Nowadays, heavy traffic has become the source of greatest complaint in many big cities. As it has seriously influenced people’s daily life and economic development, the highest priority of governments has been given to the problem and many experts have been called in for advice.

　　A great number of solutions are being offered. Some people suggest that more streets and roads should be constructed. The advantage is obvious: it can reduce traffic density and hence speed up the flow of buses and cars. But traffic flows constantly rise to fill whatever scale of roads and highways are provided for them. And in a city with booming industry, land is precious and cannot be extravagantly used for traffic. So others argue that the number of bicycles and cars should be limited while more bus routes should be opened up because buses can accommodate more passengers. But the decrease in the number of bicycles and cars might give rise to another new set of problems, such as inconvenience to people.

　　Since neither of the suggestions can effectively solve the problem of heavy traffic, there is an increased awareness that the two solutions may be combined with other possible solutions to produce the best effect.
