In recent weeks, transit has been a recurring topic on this page. An editorial documented a woeful future that threatens, due to worn out roads and bridges ('State's in a jam on transportation funds," Jan. 11). A commentary article followed, from Republican legislators, indicting the economics of streetcars ("Why the Legislature should put brakes on streetcar dreams," Jan. 18). Minneapolis officials responded with a challenge ("Streetcars, yes, and buses and more," Jan. 29), saying the lawmakers should offer up "… a BRT-only, no-rail transit system. Then we could have a real debate."
A "real debate" is welcome. But let's expand our scope to a comprehensive vision of what we can truly do with transit. Let's think and plan using our knowledge of current and emerging technology. Let's plan on the scale — with the 100-year time frame and public-private coordination — that founded our Minneapolis park system.
And let's start with a Southwest light-rail alternative — shaped by three future-focused considerations: vehicle size, service frequency and automated driving.
My proposed "Transit Revolution" approach uses Metro Mobility-size vehicles — 24 passengers and one lift. These cost about $70,000 new, compared with $3 million per light-rail car. I've run the numbers for a plan that would move the same number of people on the Southwest Corridor as light rail.
The light-rail plan features about 200 weekday trips, with about 100 people on each train. The Transit Revolution alternative averages about 10 people a trip, with about 2,400 trips a day.
Here's your obvious thought: "Bob, you're crazy! Economies of scale — it's a slam dunk — light rail is the way to go!"
Well, let me sit you down for a shocking fact: I ran the numbers for part-time drivers (we'll need almost 700) at $17 per hour. Even with about 10 times as many discrete daily trips, the $35 million annual operating cost is about the same as the Met Council's $32.7 million light-rail operating cost estimate.
Let's now consider the advantages of having 10 times as many discrete trips. The service frequency could be much higher — every five minutes or better — even including variants and supplements built into the route. We could tailor express runs for speed, with specialty runs and door-to-door shuttles to bring people to a much finer grid of destinations. Over decades, we could tailor a small-vehicle system for both speed and access in ways that those behemoth light-rail whales can't possibly match.
