　　Traffic congestion is frustrating and bothering many commuters in cities, with conflicting views on how to tackle this worrying trend. Some people claim that more train and subway lines should be constructed by the government. Others, however, believe that it is much better to widen the roads and build extra ones.

　　Providing more railway and underground lines tends to have a favorable influence on dealing with traffic jams. The key reason lies in the fact that compared with other modes of transport, a train has the capability to convey hundreds of passengers every time. Meanwhile, the track enables these vehicles to move smoothly without waiting for the traffic lights frequently. Thus the efficiency of the ground and underground railway system overwhelmingly dwarf that of others, which ensures the travelers to reach their destination on time. For these reasons, the advantages of metro can attract a large number of car owners to abandon the use of their cars and choose to commute by train. In the long run, the possibility of traffic congestion can be reduced.

　　However, this does not automatically mean that simply investing in railway system can tackle the traffic congestion. After all, not all the citizens can conveniently reach the railway station or just live besides it. Consequently, they may still choose to drive. In the case, there is still the needs for the administration to build roads both in quantity and width. In the past, the construction of roads in many metropolises was  not proportionate to the increase of private cars, which contributed to the outrageous congestion in the downtown areas. By contrast, when the advanced road system is available nowadays, cities can accommodate more cars and buses at the same time. Therefore it is less likely to see the crowed roads.

　　In conclusion, simply building train and subway lines may not ultimately tackle the traffic congestion. The government should not only invest in providing the rail transport, but also build more and wider roads.
