Structure and economics of intra-urban goods movement.

An analysis has been made of 1961-63 goods movement within the New York City tri-state region to characterize and quantify goods movement by truck, rail, barge, and oil pipelines. Data sources and limitations are discussed. It is noted in conclusion that a tunnel or subway employed to link 10% of the trading points would link only 1% of the interchanges, leaving trucks to handle the difference.
