Revise Your Ride is a program informed by behavioral science to increase commuters using alternative modes of transportation, and to decrease single-occupancy vehicles (SOV). 

Since 2008, the program has contributed to shifting the behavior of hundreds of former SOV drivers toward alternative modes, including rail and bus transit, carpools, vanpools, and biking or walking.

As of 2021, 593 faculty and staff members and graduate students— or 6 percent of all eligible commuters — use more sustainable alternatives to SOVs, contributing to improved regional air quality, reduced traffic congestion and reduced greenhouse gas emissions. Princeton also offers affordable car share programs that are increasing in popularity.
