becomes a bigger problem in major cities. Most cities grow very fast while the infrastructure stays the same. But

that is

not the only thing we should be concerned about it. Nowadays, we

would be to build better and bigger roads. But most of the time there is not enough space for that in huge cities. Most of the roads are already surrounded by buildings, and it takes a long time for construction.

Also

, working on a road will cause even more

congestion

while ongoing construction. Another option to reduce

congestion

would be public transportation. Better infrastructure can

decrease

congestion

. When more and more people would take a train, the subway or a Bus to get to work, the

traffic

would be less heavy,

a carpool lane can help. It might motivate people to travel together

instead

of everybody driving by himself. In conclusion, there are some options to reduce the

traffic

on the road. But every option has its advantages and disadvantages. Building a bigger road might be a long-term solution but it is not always possible. Building a subway or a train station is really expensive but

a long-term solution.
