@Alon I was reading the VRE's current future plan and it stuck out to me that they often talk as if mode shift where they already serve is impossible, only able to grow ridership with population growth and system expansion. This explains why they are focused on peak-capacity expansion and only considering all day, all week service until 2030's at the earliest. How common is this attitude elsewhere in incompetent agencies?

@Alon Has to be basically 0. There's supposedly 700,000~ish people who commute to their jobs in DC, and post pandemic ridership hovers around 5,900 (not sure if that's trips or riders). This is all from google so grain of salt, I need to learn how to use census readers.

@Alon
Is there a reason why the postwar American metro systems have such gigantic trains other than "NYC does it, and we're trying to be a better NYC?"

@Alon wait, what do you mean by "battery-electric buses at depots to reduce pollution" and "bus depot electrification" vs just "electrification?" What do depots have to do with it?

@Alon ah okay.
Makes plenty of sense.
Thank you for explaining!

@Alon NEOM is a real mixed bag. Yes, it's a quixotic fever dream that is basically going to be a meat grinder for south asian guest workers, but at the same time, it's bankrupting one of the worst regimes in the world right now. Impossible to say if bad or not.

@Alon So I was curious, for many stop spacing models, you usually assume that the stop cost is fixed. But with closer stop spacing, more people board at each station, increasing the stop penalty, no? Especially considering higher demand stations. Are there ways to account for this? What are the implicattions?

hikoukihikouki,
@hikoukihikouki@mastodon.social avatar

@Alon sorry yes, further so there's more people boarding at each station, whoops hahahaha. For CBD stations on subways, does that justify shorter station spacing, or just accepting longer dwells? I know the station spacing should be shorter in the CBD regardless because final destinations are closer and you can save a lot of people a lot of walking.

hikoukihikouki,
@hikoukihikouki@mastodon.social avatar

@Alon obviously it depends a lot on the CBD itself, but is there a good range for stop spacing distance within a city center?

@Alon in cities that border a large body of water, particularly those which do so along a straight-ish coast like Chicago, Barcelona, Toronto, for the transit lines that run orthogonal to the coast (think Toronto line 1, congress branch of cta blue line), is there a way to through run them in a way that’s useful to riders? Or is it better to just terminate them at the core

@Alon Here’s Potomac yards, an at grade station that cost $390M to build, and only has a single exit

@Alon quick question: why do stations right before the branch point on the Stockholm T-bana have 4 tracks and 2 platforms?

@Alon ah okay, interesting! I guess if you’re gonna be held up by a signal you should be able to collect passengers. Thank you for answering! πŸš‡β€οΈ

@Alon it is frankly bananas that people say "Switzerland accepted nazi gold" like they just took gold the nazis legitimately owned and just put it in a vault, and not that they exchanged stolen Jewish gold for currency that could be used to fuel the nazi war machine... πŸ˜“

Pedestrian Observations: Public Transit Subsidies and Efficiency https://pedestrianobservations.com/2024/02/09/public-transit-subsidies-and-efficiency/

hikoukihikouki,
@hikoukihikouki@mastodon.social avatar

@Alon It's an... interesting... choice to choose both crowding as a proxy for efficiency and per-capita rather than per-rider subsidy 🀨 . Especially considering most of the lowest per car-km costs come from systems that run more trains with less passengers off peak. The conclusion being that larger cities have more transit crowding wich... yeah...

@hikoukihikouki@mastodon.social avatar

@Alon Is it possible to do Soviet/Parisian-style headway management over junction use on highly branched systems? I.e., 3 branches running at 15 minutes each, slowing down and speeding up trains so they almost always hit the junction every 5 minutes and guarentee even spacing through the shared section and no waiting at junctions?

@Alon during the stream you said that Japan is a developmental state while Israel is less so. What's a "developmental state?" Could you point me in the direction of a good overview?

@Alon very interesting! thank you very much!

@hikoukihikouki@mastodon.social avatar

@Alon I think you've alluded to this a few times in writing but I can't recall too many thoughts expressed on transit officials and dogfooding -- i.e. using the system they run. A lot of American advocates are shocked when foreigners like Randy Clarke and Byford actually use their systems. Is America exceptional in this regard? How important is it for good transit in the end?

hikoukihikouki,

@Alon thanks for the answer 😊 I hadn't thought about the risk of elite projection.

@Alon It seems like everywhere that can build HSR has tried to make airport-HSR connections to work except Japan. Thinking like Paris Charles de Gaulle, Hongqiao, Frankfurt, etc. You have the incomplete Narita shinkansen but other than that it seems like the JR groups were very resistent to airport infill or extensions. Is there a reason? It seems like a bad idea, Korea gave up due to low ridership, but many European countries seem insistent.
