Here’s an interesting map via a recently published report from David Levinson, of MnPass holders and where they live in the Twin Cities:
I don’t pretend to know the statistical background to this, but the model’s results are interesting, showing who MnPass theoretically (and actually?) serves:
The paper estimates a binomial logit model that predicts, on the basis of aggregate characteristics of the surrounding area, the likelihood of a household having a subscription to MnPASS systems. Variables in this model include demographic factors as well as an estimate of the incremental accessibility benefit provided by the MnPASS system. This benefit is estimated with the use of detailed accessibility calculations and represents the degree to which a location’s accessibility to jobs is improved if HOT lanes are available.
Voila!
