If I was prioritizing, I would put the following first in line:
Oakland / San Jose / Los Angeles / Riverside / San Diego // Riverside / Las Vegas
Milwaukee / Chicago / Cleveland / New York
DC / Pittsburgh / Columbus / Indianapolis / Chicago
DC / Charlotte / Atlanta / Jacksonville / Orlando / Tampa.
... but the point of the approach is to set criteria and have priorities determined by who puts out projects with 20% local funding and which of those projects have the best performance in geometric mean of population served per dollar. I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
So the auction is not for the best projects proposed nationwide, but between a range of projects serving the same urbanized area.
So the legislation would define parameters for an HSR project to bid for funding out of the accounts for the municipalities and counties it serves, in project-by-project competition, all on a level playing field with the 80/20 federal local funding for Interstate Highways. I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
Anyway, the answer is, yes, I can do both the arithmatic and the geometric mean per mile of each pair ... I'm getting on that right now. I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
I did the arithmatic mean first, but it is just the sum scaled by a factor of 0.5. But since the central place hierarchy tends to be a log-linear relationship, the geometric mean felt like it was probably better.
And who knows ... one day in the distant past I may have actually read some literature that suggested that the geometric mean is the preferable measure in general for this situation ... I definitely knew a lot more abstract regional economics stuff a decade ago, even if I knew a lot less about the real world problems of fighting for better public transport. I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
antilog( (log(x1)+log(x2))/2 )
which in direct arithmatic is:
(x1*x2)^.5 I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
Lower cutoff at 100 miles, upper cutoff at 580 miles, all values to geo-mean 10,000/mile.

Odd, that.
