Las Vegas’ monorail is a great example of what not to do for a city the size of Houston. Not only is Houston much, much larger geographically, it has a vastly larger population and projected ridership.
Take a look at cities that have sections of both - Tokyo or Seattle might do. Tokyo might actually be the best, since it has just about every possible public transportation option available. There, monorail is used for comparatively little of the total ridership and track lengths. Mostly for short, specialized segments where installing light rail or subways is ill-advised (actually, mostly within amusement parks). The vast bulk of Tokyo’s rail options are full passenger rail, light rail, and subways. That is a city where every square inch of real estate is ultra valuable and one that explores every possible public transportation options, yet in which light rail is preferentially used. Do we need to re-learn a lesson they figured out decades ago?
Even in Seattle, the monorail is a short section of track connecting two heavily touristed points (no real commuter traffic) compared to the much, much longer light rail sections for regular transit.
Las Vegas? Monorail is used to connect a fairly small portion of town that is the most heavily trafficked (by tourists, at that) and already built up. It’s not really designed for the local population.
The same things are true in all these examples. Monorail is used for relatively short segments that connect at most a few heavily frequented locations and for which a full rail system may be prohibitively expensive for the gain provided.
So, sure, it might work within the Medical Center itself, with perhaps a spur to Reliant Park. But it’s ill advised for any length bit of track designed for most long distance commuting.
When did Houston turn into a live action version of the Simpsons? Do we need a shyster singing us the monorail song? Should we rename the city Ogdenville or North Haverbrook?
And meanwhile, the downtown core is being revitalized, due in some part, to the light rail and the improved access it brings. Funny how that works, isn’t it?
