The underlying purpose in developing and applying a trunk route analysis procedure was to (a) prepare reliable estimates of traffic likely to use the various main lines that make up a rail system and (b) transform resulting traffic flows into estimates of railroad costs and revenue on the basis of links, nodes, corporate systems, and regional rail systems. The objective is to identify the overall effect of proposed changes in facility usage, routings, and corporate ownership through identification of the difference between the current system and alternative plans. The developed procedure used traffic assignment principles applied to rail freight. Key steps involved (a) establishing geographic and physical facility characteristics, (b) obtaining traffic and revenue data, (c) preparing the various inputs (physical characteristics of links, zone-to-zone traffic, and likely routings), and (d) assigning traffic and calculating associated costs and revenues by using a specially prepared computer program. The procedure, developed for the Pennsylvania Department of Transportation, was used to evaluate the United States Railway Association's Preliminary Systems Plan (for reorganizing bankrupt railroads in the Northeast and Midwest) and a simple plan proposed by the Commonwealth of Pennsylvania. The resulting procedure helps fill the void for rapid, large-scale tools for policy and systems level planning. Although developed for statewide and regional rail planning purposes, the procedure and supporting computer program are general enough to permit their application to other freight modes of an intercity character. /Author/
