Nowadays, a big problem of cars on the road, is something that nobody changed but it can be reduced by improving the quality of public transport and motivating the car owners to use it. 

There are many problems with public transport. One of them is that it does not provide good comfort for the passenger and there are informal kinds of transport that should disappear because they congest traffic. In addition, they are not supervised by the authorities.

The key to limiting the use of private cars is putting up petrol prices, this will cause some drivers not to pay what is required for petrol. Another point is to place schedules for public transport and private cars. there is currently a system called "pico placa". 

On the other hand, to reduce traffic, it is necessary to limit the way into the city center or to raise rates for parking. Also, modernization of traffic lights and detached lanes give buses the advantage of driving.
