Citation needed. I've heard this quite often, but so far, I haven't seen proof of the stated causality.
PS: This doesn't mean that better public transportation could deliver more bang for the buck than the n-th additional car lane. But never ever have I heard from anybody that they chose to buy a car or use an existing car more often because an additional lane has been built.
