This is because of the concept of induced demand, where an increase in supply increases the amount of people who would use such a thing. In the field of transportation, if there are more lanes for cars, there will be more people who use the roads, and thus more traffic, the opposite is also true, as if you reduce the roads, there will be less people who will want to drive. The same is true for public transport, but it is better suited for that as it is better for mass transit.
