Mark Hansen and Yuanlin Huang, "Road Supply and Traffic in California Urban Areas," Transportation Research A, Vol. 31, No. 3, 1997, pp. 205-218.
Every 1% increase in new lane-miles generated a 0.9% increase in traffic in less than five years, which led them [Mark Hansen and Yuanlin Huang] to conclude that "With so much induced demand, adding road capacity does little to reduce congestion.":
