Salvador, Brazil
For a huge country like Brazil, you would think that traffic won’t be an issue. However, due to its population as well as poor management of road systems, a lot of cities in Brazil suffer from traffic congestion. Salvador is one of the worst in this regard. The congestion rate in Salvador increases by 46% each year. It takes about 43% more time during rush hours in the morning and 67% during rush hours at night. This could even go worse in the incoming years.
