GUIDELINES FOR CONDUCTING INTERCITY HIGHWAY ROUTE STUDIES, INFORMATIONAL REPORT NO. 8. INTERIM REPORT

This document provides the Texas Department of Transportation the initial step in developing a methodology for conducting intercity route studies. It is intended to assist the analyst in identifying the key factors that should be addressed in intercity route studies and to provide guidance in selecting the appropriate procedure(s) for evaluating these factors. In many cases the procedures presented have not been extensively tested and should be used with caution; in some cases, the procedures are either overly simplistic, in the development stage, or non-existent. Therefore, numerous "gaps" and caveats exist; recommendations for filling these gaps are enumerated wherever appropriate. The Guide consists of five chapters, four of which correspond to the four-step framework recommended for conducting intercity route studies. Several appendices provide guidelines concerning origin-destination studies, recommended data sources, descriptions of alternative methodologies, and additional documentation for selected topics which are treated in less detail in the main text.
