Dear Kyle
Thanks for reaching out. The background is that we did a cost study in 2017.

Then in spring 2024 my students drafted an updated version, that was a cost-
benefit study. The paper examined the costs (updating the prior analysis using FTA data) and potential benefits, also looking at some alternatives. However, the draft was released before we were finished and I have been on sabbatical this past year. I have a team working on it now and hope to publish it by the end of the semester.
I will absolutely let you know when it’s ready.
