Arizona's Metropolitan Travel Reduction Programs

This paper documents the short-term response to Arizona's metropolitan travel reduction programs. The Phoenix (Maricopa County) and Tuscon (Pima County) programs were initiated in 1988. Their legislation, specifications of travel reduction, initial actions, and achievement to date of travel reduction objectives are presented. The Tucson program reports that major employers achieved an average 20.2 percent alternate mode usage by their employees for the program's first compliance year (1990). Preliminary findings from the Phoenix program indicate a 4.7 percent reduction in single occupant vehicle trips in this program's first compliance year (1991).
