“Downs-Thomson paradox, also referred to as the Pigou-Knight-Downs paradox, states that the equilibrium speed of car traffic on the road network is determined by the average door-to-door speed of equivalent journeys by (rail-based or otherwise segregated) public transport. It follows that increasing road capacity can actually make overall congestion on the road worse."Sounds like some sort of variation of induced demand.
