Gondolas are slow and while they have high headways, so should other primary forms of transit. The fact that the MAX Teal has 20 minute peak / 28 minute offpeak headways isn't a natural disadvantage of BRT that gondolas can take advantage of; it's a failure from a lack of investment in core transit services. MAX routes should have 10 minute or less headways (lower in peaks); the LRT should be 5-7 minutes and lower in peaks.
A gondola from Westbrook to MRU makes no sense; it's a short trip with existing relatively uncongested roadways. For the cost of operating two buses as a shuttle, that would be 12 minute headways; for the cost of 3 buses, 8 minute headways. The headway savings for a gondola are minor in this case -- maybe 5 minutes on average (less the time it takes to get up to the gondola station).
On the other hand, when you have substantial elevations and a river to cross, not to mention all of the other restrictive land uses, a gondola connection from Westbrook to Brentwood serving the Foothills and U of C makes a fair bit of sense. Not necessarily because gondolas are a great form of transit on their own, but
because the alternatives are all terrible -- a surface right-of-way involving a substantial bridge in environmentally sensitive terrain, a ridiculously expensive underground project, or the existing road network, where to go under 3 km from Westbrook to Foothills a bus has to drive twice as far over the highly congested Crowchild bridge. It's an important connection, but not a primary one.
Here's my quick crayon, including optional stations in Spruce Cliff and Parkdale (small circles), additional towers and alternate route that adds in the Children's hospital (there are a lot more adults and seniors that take transit to medical appointments than children):
(One complicating issue with gondolas to hospitals is that some gondola designs assume pretty high levels of mobility from their users -- with cars that never stop moving. High personal mobility is a pretty good assumption when you're ferrying downhill skiiers, but less so with the clientele of a hospital. There are designs that work; the Portland aerial tram serves a hospital; but not all of them will.)
