UDOT has posted an update to the POM study. I poked through the hundreds of pages of materials and pulled out these interesting bits:
The proposed alignment for all modes has been refined and largely consolidated.
LRT costs twice as much as BRT initially, once built operation costs are similar to BRT. Ridership on LRT would be considerably greater. DMU would cost more, function worse, and carry fewer people than LRT.
Operating as an extension of the Blue Line was removed from consideration. A non-revenue connection along the existing ROW from Draper to The Point would eliminate the need for a dedicated maintenance facility, and would be studied if LRT is selected. They also throw some shade at the idea of a second Frontrunner Station in Draper.
Cost and design considerations by mode.
More detailed breakdown of maintenance operations.
All said, this study is taking a massively different direction from UTA's study. I am hopeful that they will select LRT as the alternative in December when they wrap things up. DMU seems to be DOA as a mode here, it costs more and carries fewer people. UDOT has really broken things down way more than UTA did in their study, they even have conceptual plans for all three modes.
UTA's study ranked the capacity of BRT and LRT as being roughly the same, this study shows that it would be dramatically different.
Consider these two selections from
UTA's 2021 study:
Their cost findings are radically different compared to UDOT's. I believe that UDOT is leaning towards LRT based on the new findings regarding ridership over the long term and operating cost.
