This report serves as both an analysis of current trends in ridesharing and a toolkit for public agencies, large and small, to create ridesharing programs tailored to meet the needs of their respective constituencies. Best practices from around the U.S. are illustrated in a series of case studies, and the report also contains a step-by-step "how to" guide for implementation. The report concludes with a comprehensive database of both public and private sector entities already engaged in ridesharing around the world.
