THE LOCATION AND SIZING OF URBAN FREIGHT TERMINALS WITH MULTIPLE PLANNING PERIODS: THE URBAN TERMINAL INVESTMENT MODEL (UTIM)

The purpose of this research was to develop and test an Urban Terminal Investment Model (UTIM) for use in the design decisions required to locate, construct, and operate a network of terminal facilities. Several overall criteria are presented as guidelines to produce a model and a solution procedure which permits terminal planning on a routine basis. This research has led to a design methodology which is currently operational for use by transportation planners. The methodology is implemented with computer programs collectively called UTIM. This document contains an investigation of the economic advantages of consolidation terminals for the distribution of small-shipment freight in large metropolitan areas. Planning models for two different system operating rules which assign freight flows to terminals are developed. The models are designed to identify least cost terminal system configuration which are valuable in assessing the economic attractiveness of freight consolidation relative to other goods movement methods. The UTIM models are nonlinear integer programs which are solved with new partial enumeration methods developed in this research. The research results included realistic evidence for potential economic superiority of multiple terminal networks over a single facility, namely, for cities whose metropolitan areas are charcterized by spread out commercial zones and concentrated truck carrier locations. Application of the UTIM models was tested, using data for the Columbus, Ohio, area. For this analysis, the least cost configuration was a single consolidation facility which was estimated to permit significant cost savings over the current goods movement system. /UMTA/
