Load Factor, 1988-1991
- Scope and content:
-
TAB undertook an initiative between 1988 and 1991 to update load factors (the number of adult passengers per vehicle) by region and roadway type to more accurately capture panel circulation. The existing load factor number, 1.75, was based on outdated research from the 1930s. TAB sent requests for proposals and received research proposals from Market Information Services of America Inc. (MISA) and Wilbur Smith and Associates, eventually contracting the former. The series also contains the final research study and follow-up reports from MISA.
