Promoting ride sharing: The effect of information on knowledge structure and behavior. Executive Summary

Abstract

The findings indicate that story-based information is more effective than factual text at conveying intangible aspects of carpooling and at creating a deeper understanding of issues related to carpooling. However, the study also suggests that increased knowledge and changed perceptions of carpooling are not enough to change behavior; any information campaign must be preceded or accompanied by a concerted effort to remove other significant barriers (e.g., scheduling problems, emergencies, not knowing people with whom to carpool). Lastly, it suggests that a combination of factual and story-based information may be the most effective way to change the way people think about carpooling and, ultimately, to encourage people to carpool, particularly in a work setting.
