The Cost of Lowballing Light Rail Ridership Projections

The Overhead Wire has picked up on a piece in Saturday’s New York Times about how light rail ridership in Phoenix has exceeded expectations. The post points out that this isn’t the first time the Federal Transportation Administration has underestimated demand for similar projects, a pattern that has the potential for real consequences:

Yay, FTA Models. You totally rule at figuring out ridership in new light rail cities. You did a bang-up job in Minneapolis (24K in 2020, current 26k), really got those Houston numbers right for 2020 (33k in 2020, current 38k), and Charlotte was right on target (9k
opening, current 14k). Note: the APTA daily numbers are a bit wonky. I
don’t know if I completely trust them to the rider but they make the
point.

Now we can add Phoenix to the list of FTA model lowballing: “The
rail was projected to attract 26,000 riders per day, but the number is
closer to 33,000, boosted in large part by weekend riders.”

What
kills me about all this lowballing is what the cost-effectiveness
number was — and what it SHOULD have been. Ultimately, that is what
decides projects. And it’s a little messed up that the FTA keeps
getting it wrong, especially when they can kill a project because of a
CE below Medium.
