TRB's Transit Cooperative Research Program (TCRP) Report 111: Elements Needed to Create High-Ridership Transit Systems explores the strategies used by transit agencies to create high ridership. The report includes case studies that focus on the internal and external elements that contributed to successful ridership increases and examines how the transit agencies influenced or overcame internal and external challenges to increase ridership. The report includes a companion interactive CD-ROM that contains a database of individual transit agency ridership strategies linked to the strategies and examples presented in the report. The CD-ROM also contains a brochure that outlines the key elements identified in this report for increasing and sustaining ridership.
