AN ANALYTICAL TECHNIQUE FOR IDENTIFYING FREEWAY AND EXPRESSWAY SYSTEMS AS PART OF THE RURAL STATE HIGHWAY SYSTEM

A LINK-ANALYSIS TECHNIQUE, WHICH RELIES ON MULTIVARIATE STATISTICAL PROCEDURES, IS PRESENTED AS A POSSIBLE GUIDE FOR DESIGNATING MAJOR RURAL HIGHWAYS INTO FREEWAY, EXPRESSWAY, AND OTHER MAJOR RURAL ROAD SYSTEMS. THE LINK-ANALYSIS TECH- NIQUE GROUPS ROAD LINKS INTO SYSTEMS ON THE BASIS OF THE FUNCTIONAL CHARACTERISTICS OF TRAVEL ON EACH LINK. AFTER THE GOALS AND OBJECTIVES OF THE MAJOR HIGHWAY SYSTEMS ARE FORMULATED, A CRITERION FUNCTION IS IDENTIFIED TO SELECT HIGHWAY LINKS TO BE INCLUDED IN EACH OF THE THREE SYSTEMS. MEASURES SUCH AS AVERAGE TRAFFIC VOLUME, AVERAGE TRIP LENGTH, AND PERCENTAGE OF COMMERCIAL VEHICLES ARE USED TO PLACE ROAD LINKS INTO SYSTEMS BASED UPON A MODIFIED REGIONALIZATION GROUPING PROCEDURE AND MULTIVARIATE DISCRIMINANT ANALYSIS. APPLICATION OF THE MODEL REQUIRES THE AVAILABILITY OF A STATEWIDE TRAFFIC MODEL TO DEFINE THE EXISTING OR PROJECTED TRAFFIC DEMANDS FOR EACH ROAD SECTION. ALSO PRESENTED ARE THE RESULTS OF TESTING THE TECHNIQUE ON THE MAJOR RURAL ROAD SYSTEM IN SOUTHERN ILLINOIS. /AUTHOR/
