>Frank Hedley, general manager of the Interborough Rapid Transit Company, said in October, 1904 that the subway was designed for a maximum daily capacity of 600,000 passengers...traffic surpassed the 800,000 mark in 1908 and reached 1.2 million six years later.Direct induced demand pushing traffic beyond design capacity.
>The traffic situation throughout New York when the New York subway was opened was simply a question of calculation, a matter of opinion, as to how many passengers the elevated roads would carry after the subway opened. The subway was opened, and we carried large numbers of people down there. The business on the elevated has not fallen off to the extent that was expected> Between 1904 and 1910 the surface railways transported an average of 372.5 million passengers, four percent less than the 1904 total.Without substantially alleviating congestion on the original routes.
Growth in passenger numbers was in advance of overall population growth, and beyond their projections (which included population growth).
