Morgantown PRT has 20-person capacity cars. That doesn't seem so inefficient. On the other hand, it only operates as a PRT during off-peak according to the wiki page - during peak hours, it's just a standard scheduled service like a train or bus.
That said, the Musk Loop type plans where the cabs/cars only carry 1-4 people - which seems similar to this SkyTran - is obviously inefficient and not really a realistic alternative to cars or mass transit systems.
- billytetrud 6y ago> is obviously inefficient You only think that because you haven't done the math. Its frustrating to hear people talk about how something is "obvious" when by "obvious" they just mean "I haven't actually put any thought into it. A single Skytran track has more capacity than 7 lanes of freeway or 3 tracks of light rail. Does that sound "obviously" inefficient to you?
- jcranmer 6y agoI call BS on that math immediately. A lane of freeway can move about 1500-2000 people per hour in single-occupant vehicles. If you're moving 2k people/hour in 4-person cars on a fixed guideway, you need to have about 10 seconds between vehicles. That's about 8 seconds for a car to physically clear the switch, the switch to physically move to an alternative position, and then the trailing car to cross the space needed to come to a complete stop should the switch fail to actually work. If you claim 7× the capacity, you need to do all of that in a little more than a second. So, yes I have "actually put any thought into it." I've put sufficient thought to recognize standard gadgetbahn claims with standard gadgetbahn levels of evidence backing them up, and thus I can respond with standard gadgetbahn criticisms.
