At scale, the project forecasts 2200 bikes supported by an annual operating (not build out) cost of $4.6 million. That’s $2090/bike. It forecasts 2.68 million trips per year at an average of 2 miles/trip. If those numbers are accurate, a trip would cost $1.72. A mile, $0.86.
I don’t have a strong reaction to those costs. I would gladly pay $2/trip myself as an entirely usage-based fee. The forecasted cost is in line with Metro and Sound Transit fares. While it’s lower than their costs per boarding (for Metro, $3.70 in 2008; source), the shorter, denser routes are much cheaper to deliver than the system-wide average.
The data to compare route-level stats doesn’t exist. Shorter, denser routes are the closest comparables to phase 1. However, one could see bike sharing allowing the last mile of trips that would have otherwise been taken by car (and instead use bus or train). Not enough data to know.
My own conclusion: the costs are definitely “in the zone” for transit and might be a little cheaper than existing options.
Crucially, the total cost is incredibly small compared to any other transit implementation, and thereby, much lower risk. As a point of reference, Metro received $37.5 million to add 2 RapidRide Bus Rapid Transit (BRT) routes (source). Even excluding all other revenue sources, the total build out costs of all phases are equivalent to one BRT route.
As another perspective, the 4.3 mile Northgate light rail extension has a lifetime budget of $2.1 billion (70x-100x more than the total 5 year projected cost), and the South Lake Union Streetcar was $56.4 million (source).
I don’t mean to provide these as comparables. For me, the lower cost just means the barrier for my endorsement is much lower. In urban transit, $20 million is an experiment. In this case, the “experiment” happens to fund the whole system.
relies on internally-created usage forecasts. While the forecasted 2.4 trips/bike in year 1 is within the range seen in other cities, that range is very broad (0.9 to 3.7). As you’d expect of a transit system, usage is the key to a low cost per trip.
ignores the $14.4 million in build out expenses because they do seem to be one-time (stations) or long depreciation (vending machines), and because the report notes “presenting sponsorship is expected to cover all but $2.15 [of] .. $14.4 million.” The unfunded 2.15 million is not a material impact.
