How to Solve the Problem of Heavy Traffic
With the development of industry and economy, more people from rural area are pouring into big cities and more vehicles are going on to the street. As a result, many cities are faced with the serious problem of traffic congestion, which has become one of the major concerns of the society.
To solve this problem, many people have put forward many solutions, of which the following two are the most typical. One is to lay down more roads, which will make the highways less crowded and accelerate the flowof traffic. Another is to open up more bus routes, which will enable more people to take buses rather than ride bikes or drive cars, thus decreasing the number of cars and bikes racing on the streets.
However, both of the suggestions have disadvantages. The former may occupy too much land, which may be otherwise put to better uses. The latter, on the other hand, will bring inconvenience to those who are living far away from the bus routes. The best solution, in my opinion, seems to be the combination of the two: toay down more roads in spacious areas and to open up more bus routes in downtown areas.
