TRENDS IN TRAFFIC DIVERSION ON EDENS EXPRESSWAY
A BEFORE AND AFTER STUDY WAS CONDUCTED ON THE EDENS EXPRESSWAY IN THE CHICAGO AREA. THE EXPRESSWAY WAS LOCATED & DESIGNED ON THE BASIS OF A 1941 ORIGIN-AND-DESTINATION SURVEY. THIS BEFORE AND AFTER STUDY WAS CONDUCTED TO ADD KNOWLEDGE TO THE FIELD OF TRAFFIC ASSIGNMENT. THE COMMONLY ACCEPTED PRINCIPLE SUBJECT DIVISIONS IN TRAFFIC ASSIGNMENT ARE: (1) TRAFFIC DIVERSION, (2) TRAFFIC GENERATION, AND (3) NORMAL GROWTH. THE DATA ACQUIRED FOR THIS COMPARATIVE ROAD INTERVIEW SURVEY INCLUDED NOT ONLY ORIGIN-AND-DESTINATION, INFORMATION, VEHICLE TYPES, AND VOLUMES, BUT ALSO TRIP PURPOSE DATA. TO ESTABLISH A MEASURE OF COMPARISON BETWEEN 1950 AND 1954 TRAFFIC VOLUME, A NORMAL GROWTH FACTOR HAD TO BE DETERMINED. IT WAS DECIDED THAT AN UNBIASED ESTIMATE OF NORMAL GROWTH COULD BEST BE ACHIEVED BY SELECTING AS A BASE THE VEHICLE REGISTRATION 1950-1954 INDEX WITH THE LIMITS OF THE SUBJECT CORRIDOR. RESULTS OF THE TRAFFIC STUDY ARE PRESENTED IN GRAPHS AND TABLES.
