I believe that that decision is based on all of those, only considering one or two can be dangerous.
Also, along with that whole Bus to BRT to Light rail, do you think it is possible that the Utah county TRAX line could eventually be extended along the provo Orem BRT route? (Im talking like 2040+) They both end at the Orem frontrunner station and it makes sense to me to continue it into downtown provo/BYU. Also in the Draft Master Plan it talks about an eventual light rail extension into the springville and spanish fork area, would this have anything to do with that?
