We need to encourage people to use the public transportation system, such as, metro, train, buses or even shuttle. To achieve this goal, we can return part of the taxes belong to the people who used metro for a year, or a family who have just one family car. Also by increasing the number of buses in our cities, people will encourage to use buses. By purchasing a couple of hundred new modern and elegant buses also we can catch everybody's attention to use them.
These three solutions will make traffic lighter, but certainly will not solve the traffic problems. Finally by training our next generation to replace a bicycle with a car in the short trip .we will solve the traffic problems slowly over the years.
