From the Voice of OC:

California High Speed Rail Authority board members listened, but took no action, Thursday when they were told in person that ridership estimates they're using to plan the 400-mile rail system are unreliable.... Brownstone is part of a team of UC researchers who last week released a study showing that based on the ridership estimates used by the Rail Authority, it is impossible to know if the $43-billion system will succeed or fail. On Thursday, Brownstone detailed for the board why the study came to that conclusion. One problem, Brownstone said, with the estimates provided by the Rail Authority's subcontractor, Cambridge Systematics, is that no one knows what the margin for error is. Or if someone does know, that someone isn't telling.
