Freight Network Modeling System. Volume V. Flexible Network Definition Software User's Guide

Technical Report ·
OSTI ID:6928823

This volume is a user's guide for the flexible network definition software that allows the user to manipulate the basic data files to design a network suitable for a particular study. The flexible-network software allows the user to automatically define study regions of any size (county to multi-state) and to use different levels of transportation network detail within each region. This allows the user to model a completely detailed transportation network in the regions of primary interest while modeling movements to and from these regions on an aggregate network in the surrounding regions, thus reducing computational requirements. Because of this flexibility and the numerous support data bases, the flexible network definition capability makes it easy to set up the Freight Network Equilibrium Model (FNEM) or the Shortest Path Analysis and Display (SPAD) program for a new study. The network data bases include data on the rail, highway, water, and pipelines systems in the United States. FNEM is a predictive model that simulates the decisions of both shippers (buyers and sellers of goods) and carriers (rail, truck, and barge operators) and takes into account the competition for transportation facilities and congestion delays caused by all freight movements. The Model produces as output detailed routings, cost estimates, and delay estimates for all shipments and total traffic levels on all facilities.
