Abstract

This paper outlines a computer-based methodology that may be used to estimate traffic diversions resulting from limited restructurings of the U.S. railroad system. A basis for the methodology is presented. Coefficients of diversion for various combinations of carriers and routings are suggested on the basis of experience and historical data. The availability of the 1 percent National Carload Waybill Sample data and of the Princeton version of the Federal Railroad Administration Network Model now makes it possible to carry out before-and-after diversion analyses rapidly by means of a computer algorithm. A preliminary application of these techniques to the restructuring proposal between the Illinois Central Gulf and the Southern Railway Company arising from recent legislation is described. The potential use of the results of the methodology as a basis for the planning of capital expenditures is discussed.
