Elon Musk's Las Vegas Loop Might Only Carry a Fraction of the Passengers It Promised (techcrunch.com) 119

The Boring Company's Las Vegas Convention Center loop "will not be able to move anywhere near the number of people LVCC wants, and that TBC agreed to," reports TechCrunch. The LVCC wanted transit that could move up to 4,400 people every hour between exhibition halls and parking lots on the Los Vegas Strip. According to planning files reviewed by TechCrunch, "the system might only be able to transport 1,200 people an hour -- around a quarter of its promised capacity." From the report: Fire regulations peg the occupant capacity in the load and unload zones of one of the Loop's three stations at just 800 passengers an hour. If the other stations have similar limitations, the system might only be able to transport 1,200 people an hour -- around a quarter of its promised capacity. If TBC misses its performance target by such a margin, Musk's company will not receive more than $13 million of its construction budget -- and will face millions more in penalty charges once the system becomes operational.

So what is stopping TBC from transporting as many people as both it and the LVCC wants? There are national fire safety rules for underground transit systems that specify alarms, sprinklers, emergency exits and a maximum occupant load, to avoid overcrowding in the event of a fire. Building plans submitted by The Boring Company include a fire code analysis for one of the Loop's above-ground stations. The above screenshot from the plans notes that the area where passengers get into and out of the Tesla cars has a peak occupancy load of 100 people every 7.5 minutes, equivalent to 800 passengers an hour. Even if the other stations had higher limits, this would limit the system's hourly capacity to about 1,200 people.

The plans do not show any turnstiles or barriers to limit entry. Even without the safety restrictions, the Loop may struggle to hit its capacity goals. Each of the 10 bays at the Loop's stations must handle hundreds of passengers an hour, corresponding to perhaps 100 or more arrivals and departures, depending on how many people each car is carrying. That leaves little time to load and unload people and luggage, let alone make the 0.8-mile journey and occasionally recharge.

      The system is supposed to be able to move 4,400 people per hour. Even if they are able to do it, who the fuck wants to be anywhere that busy and crowed?

      • It's specifically designed for conventions, which are by their very nature busy. The point of the system is to move people around the convention center without forcing them to move through the convention center (which would make said convention center even busier).

        Or in 2016 when he said they'd make half a million vehicles in 2018. He did almost half as much as he said he would, so close enough!

    First, if each station in the loop has a capacity of 800 people departing per hour, and there are three stations, isn't the total capacity 2,400 people per hour?

    Second, the fire safety laws limit the number of people queued up, not how fast the queues move. They're leaving 7.5 minutes for people to get out of the car, and another set of people load in, which seems quite conservative. And if people unload and load faster than the 7.5 minutes, then of course the throughput could go up. And 7.5 minutes seems like a very slow estimate of the time it takes 4-5 people to get out of a car, and another 4-5 people get into the car, even with some luggage.

        Um, what he said. +1.

        Humans are as bad as cattle when it comes to herding them on and off conveyances. Think escalators. The physical space required to queue up awaiting boarding passengers while still getting the passengers off is no small feat. Doors on vehicles open only so wide, and people take time to move in and out.

        I spent the last couple years working on the design of the LAX Automated People Mover, and at capacity is about 10k passengers per hour. There's four cars per train, two doors per car, and (I think) SRO is like 50 people per car. Each stop is about 40 sec dwell time, and the overall end to end travel time for the 5-station, 2.25 mi (~4 km) route is 10 minutes. It's two-lane separated direction so trains can pass without interaction. In a given direction, trains run every 120 sec or so. https://www.lawa.org/-/media/l... [lawa.org]

        It's one thing to move bodies along a route - the vertical movement in and out of a station is a huge deal as well.

            Those "fire laws" seem not to make much sense either, when I'm in Paris at Gare du Nord, I easily see 1000 ppl at the same time in front of my eyes.

            Again with the lies. The article doesn't say anything is "impossible", it says that "Fire regulations peg the occupant capacity in the load and unload zones of one of the Loop’s three stations at just 800 passengers an hour." It's about fire regulations, not loading speeds, and it concerns what is needed IN CASE OF FIRE.

              Yes, the author of the article interprets the fire safety regulations to mean that, but when they quote the regulations, the regulations only restrict the number of people allowed in the area, not the throughput, so the author got it wrong.

        Except that the area that only allows for 100 people per 7,5 minutes (800 people per hour) only serves the right-hand side of the vehicles, as can clearly be seen from the diagram. The left-hand side comes from the 200-person queue area.

        This whole "some guy looked at some fire code filings and decided that the system won't meet capacity" notion is farcical on its face. What is the notion, that nobody in Boring Company noticed? Or that they noticed but decided to do nothing about it because they didn't wa

        • by dfghjk ( 711126 )

          And again you are wrong, intentionally. The load/unload area serves the entire vehicle, not just one side. Which side you get into or out the car is irrelevant.
          No matter where you step when entering or leaving a car, you're in the load/unload zone.

          "This whole "some guy looked at some fire code filings and decided that the system won't meet capacity" notion is farcical on its face. "

    • > First, if each station in the loop has a capacity of 800 people departing per hour, and there are three stations, isn't the total capacity 2,400 people per hour?

      It's my understanding that the limit is for the underground station, people getting off the train and the people getting on.

    • by AmiMoJo ( 196126 )

      The Boring Company document in TFA says that the load limit is 100 people per 7.5 minutes, meaning that is their realistic estimate of the time it will take for arriving passengers to exit the vehicles and unload their luggage, then for the cars to move around the platform to the loading points and the new passengers to load their luggage and enter the cars.

    • by dfghjk ( 711126 )

      No, because a person must both enter AND leave, meaning you need 2400 events per hour to support 1200 people per hour.

      Also, don't be like REI and SuperKendall and view this as how fast you can get into and out of a car. It's about occupancy standards for the size of the platforms, not whether you have luggage.

      A tunnel has a limit to how frequently a car can enter or leave it. You want to exploit that as much as possible but fire codes say there is not enough load and unload area. That's the issue, not whe

      • by laird ( 2705 )

        Time to unload and load, times number of vehicles and passengers per vehicle, is what determines throughput capacity.

        Number of people in the building at one time is what's limited for fire safety.

        The two aren't directly related. If you doubled the size of the building, to allow twice as many people to line up, that wouldn't improve throughput at all.

      • by laird ( 2705 )

        The document in the article doesn't talk about separate unloading and loading "events" it talks about the rate of vehicles leaving, meaning that they unload, the new passengers load in, and the vehicle departs.

        If it were "events" then they'd be estimating that it would take 7.5 minutes for people to get out, another 7.5 minutes for the new passengers to get in, meaning 15 minute cycle types, which isn't what what it says.

      • How people behave in an emergency is at issue here, not whether you need 7.5 minutes on your best day.

        Horse Shit. This fire regulation uses is tied to how people behave at peak capacity on your best day, not in an emergency, because that is the data you have when you're planning, before any emergency has happened.

        The smart people already walked around with clipboards to compare how capacity in an emergency varies compared to normal, and they took that into consideration when making the rules.

      Why does this sound ridiculously small?

      Because it is ridiculously small. It's a tiny contract for a tiny prototype line serving only three stations. Its success thusfar recently gained them approval to build a vastly larger network, however, serving the Vegas strip, airport, and downtown. Success in that will gain them contracts to cover even more of Vegas and help them land contracts in other cities. Repeat.

  • What a shock, Elon takes another tax payer organisation to the cleaners with over hyper looped promises ...
    • This has nothin to do with the tunnel and 100% on the station design not complying with fire regulations.

After all, they are just burdensome regulations that saddle companies with needless restrictions that prevent American Innovation, such as inventing means of immolating thousands of passengers simultaneously inside a giant tunnel. That's true innovation, right there.

  • Finding out at this point that there are fire code restrictions that will limit the amount of traffic to be far below what was promised seems to me to be pretty darned sloppy.
  • The article makes a stupid mistake, and then runs with it. The 100 people / 7.5 minutes quantity is the maximum accumulation of people in the station, not the number of people that are allowed to pass through the station. If you can load people in the cars and send them off at the same rate that people enter the station, there is zero accumulation

  • so glad we have these "jeniuses" running around to show us all how it's done... badly.

  • Right now they're specifying the load based on 7.5 minutes between transports. Transit systems routinely operate with far less time between vehicles, down to 2 minutes or less. The capacity of this loop can be increased substantially by running vehicles more frequently, though it will require a larger fleet of them. Eventually you hit diminishing returns because you can't get people on and off the platforms quickly enough.
  • If the other stations have similar limitations, the system might only be able to transport 1,200 people an hour -- around a quarter of its promised capacity.

    So, simply apply the lessons Musk learned from inventing the Internet (he invented that didn't he, a few years before he invented packet switching?), and divide the stream into smaller packets which can be routed more efficiently. Divide with an axe, or a high-speed freezer and a log chipper ; reassembly with ... needle and thread? Superglue?
