Cambridge Systematics, Inc. (CS) stands firmly behind the ridership and revenue model our experts have created for the Metropolitan Transportation Commission and the California High-Speed Rail Authority. We provided detailed, credible responses to multiple inquiries from Institute of Transportation Studies (ITS) regarding our approach, assumptions, conclusions, and the guidance provided to us by an independent peer review panel of international modeling experts. Except for ITS’ acknowledgment that our team "followed generally accepted professional standards," we emphatically disagree with the authors’ conclusions that the ridership and revenue model is not reliable. We are proud of the work that was done and we look forward to discussing the ITS Report with the Authority Board on July 8.
