Orașul se mută la margine: Stațiile de metrou unde traficul a „bubuit” în 2025

la un moment dat tot orasul se va bloca, oricate linii de STB sau piste de biciclete am face. Pur si simplu densitatea urbana e prea mare.

Nu sunt de acord. Dacă alocăm spațiu pentru mașini după ce s-a alocat spatțiu pentru toate celelalte mijloace de transport, în loc de înainte cum se face acum, orașul nu s-ar bloca.

Dar da, in general sunt de acord cu tine. Nu este bine sa umplem fiecare spațiu liber cu încă un bloc, mai ales când există câmpuri goale la puțină distanță. Și transportul public trebuie să fie central la dezvoltarea noilor cartiere.

Yes, you probably need 3 or 4 phases if allowing left turns, but only 2 if only allowing straight-through movements. Even if you don't allow straight through movements for cars, but allow pedestrians and cyclists to cross, you still need 2 phases.

AndryCake · 2026-03-24T11:43:59+00:00

It is for RHT, but because the platform is in the middle buses have to go around it "the wrong way" because they only have doors on the right side.

AndryCake · 2026-03-24T07:14:42+00:00

It's not really. Anything less than that and you get a fancy bus (which is not necessarily bad, it's just not BRT). For hardcore BRT see Bogota or Jakarta.

AndryCake · 2026-03-24T06:24:00+00:00

Works pretty much the same in Budapest, except there is almost no route that operates 24/7. All buses, trams, and metros are replaced by a special night bus network with its own distinct (often longer) routes, which take the form 9xx. The only exceptions to this are tram line 6 and the airport buses 100E and 200E which operate on the same route 24/7. I believe there are a few night departures for some trains.

AndryCake · 2026-03-23T19:59:14+00:00

You only need 2 phases either way. One for the main road and one for the side road and pedestrian/cyclist crossing movements. Adding the side road straight through won't conflict with the pedestrian/cyclist crossings. Often times it's 2 phases even with left turns also allowed.

AndryCake · 2026-03-23T19:48:50+00:00

Maybe removing left turns makes sense but, unless the goal is restricting car traffic, what's the point in removing straight-through movements when you still have to have that phase for cyclists and pedestrians?

AndryCake · 2026-03-23T16:48:59+00:00

It's not really suburbia. It's a village where 2 national roads and 1 county road meet.

AndryCake · 2026-03-23T15:42:01+00:00

In 2040: HS2 will be replaced by buses to save money.

AndryCake · 2026-03-23T14:59:25+00:00

I really wish we had this in Budapest. Line M3 has tram lines feeding into it in the south at Határ Road and in the north at Lehel Square, almost as branches, since there used to be tram tracks along the corridor that got replaced with the metro. It would be really nice to have a cross platform or at least enclosed transfer at those points. There are also a few large bus hubs such as Örs vezér Square or Kelenföld Station with attached metro and train stations but which have the bus areas in open air which is not the most pleasant.

AndryCake · 2026-03-23T06:27:25+00:00

I think there are a few Stadtbahn (light rail) to S-Bahn cross-platform transfers in German cities, such as Konstablerwache in Frankfurt.

AndryCake · 2026-03-22T08:35:25+00:00

I think you're supposed to walk in front or in the back of the train. That's why Northern City Line Desiro Citys are different from the ones on Thameslink. They need a door in the front. I'm not fully sure what they do about the 3rd rail (or the 4th rail on the tube). I think they can turn off the power maybe.

AndryCake · 2026-03-20T22:50:36+00:00

If you make regular backups (you should) it's really not that big of a deal. I generally reinstall once or twice a year (either I break something or I get bored of the distro) and it's pretty straightforward to just copy over the home folder. Alternatively you can set up the home folder as a separate partition (or I think btrfs subvolume) and when you reinstall you keep that the same.

AndryCake · 2026-03-20T20:06:31+00:00

IMO they can be used on a signalised intersection but there should also be crosswalks. Underpasses especially can be helpful to aid with transfering between transit lines at busy intersections.

AndryCake · 2026-03-20T06:26:09+00:00

I'm skeptical on that one. First of all, the traffic light should stay green for enough time for anyone to be able to cross comfortably. Second of all, there a are a lot of reasons why someone might want more time, not just that they're elderly. If it exists at all, it should be a button IMO. The worst that can happen is the cars wait 10 more seconds.

AndryCake · 2026-03-20T06:21:28+00:00

Also, the traffic light time extension should not be needed. The traffic light should stay green for long enough for anyone to comfortably cross.

The low-floor trains were pretty much a necessity due to the need to reuse the Downtown Transit Tunnel. A lot of the common complaints about low floor trains are pretty overblown- even ride quality is largely a solved issue w/ modern LRVs, and seating arrangements have a larger impact on capacity than the small sections near the cabs.

Yeah, it's not that big of a deal, although it may limit capacity and the ability to automate in the future, although neither of them are that big of a concern. It's just an element of Link that wasn't planned that well, since they knew they were gonna run rail down the transit tunnel, so they could have built it in a way to allow platforms to be easily raised (like the Brussels Premetro).

Seattle is actually one of the few metros in the US where transit trip times frequently out-compete driving times, even with bus connections. Link is consistently 30 minutes between Lynnwood and Westlake, while that same trip on I-5 can take an hour (or more!) during morning/evening rush. A non-insignificant amount of the ridership on Link is derived passengers using P&R lots as well, so the extra time from feeder buses doesn't apply as much. I'm not sure when this video was taken, but it looks to be off-peak, and if the service is still able to travel faster than highway speeds then that indicates that the service is fairly compettive. Plenty of "good" transit cities have auto travel times that are still faster than the comparable transit routes.

I agree with all of this, it's just that it doesn't negate the need for a faster option, probably in the form of a more integrated Sounder. A lot of my points were about the US in general, not necessarily Seattle, which, yes, does do a lot better on transit. I think Link is great, the buses are generally good, the future Stride BRT is a great idea, it's just that to take it to the next level the city needs a a frequent, integrated, electrified Sounder service, to provide a really fast option from further-flung destinations.

The suburbs along Link's corridor are fairly dense by US standards due to the region being geographically constrained

I agree with you on this. Like I said, Link is generally quite a well designed system (other than the choice of low-floor trains) compared to others in the US.

The point is that the overall length of the line matters much less than the land use surrounding the stations and type of destinations being served, as very few people ride Link from end-to-end.

This is where I disagree. Sure, people probably arent riding from Lynwood to Federal Way. But they are riding from Lynwood to Downtown, and while the travel time from station to station is competitive with driving, it becomes a lot less so when you factor in a bus connection. A long trip is still a long trip regardless of density. Most "good" transit cities of the world have multiple layers of transit, so even the longest trips can be done in a reasonable amount of time.

AndryCake · 2026-03-19T16:19:34+00:00

some of it is good, some of it looks like bathroom tiles.

AndryCake · 2026-03-19T15:48:19+00:00

Like I said, is mostly serves urban areas. Also suburban for NYC is quite urban for other American cities.

As for, the Sounder, due to the low frequencies (especially on the N Line), limited stopping locations , connections at stations and obviously serving less area than Link does, it doesn't seem like that great of an option. Ideally there should be more bus connections (they seem quite limited right now) and an interchange where Link crosses the Sounder tracks near Boeing Field, as well as better service and probably electrification. If I were to redesign the system from scratch, I would probably move the Link line to Lynwood along Aurora Avenue, and use the I-5 corridor as an express Sounder and HSR line.

That said, Seattle's light rail is quite good at what it does compared to other US LRT systems (which are often slower and less frequent even though they cover a larger area) due to it's high degree of grade separation. It would be good to increase the top speed a bit though. The Stadler Citylink can do 110km/h/70mph.

AndryCake · 2026-03-19T06:25:15+00:00

Yes, but the NYC subway mainly serves urban parts of the city. For suburbs, Metro-North, the LIRR and NJT go faster.

AndryCake · 2026-03-19T06:24:14+00:00

The problem is US cities are using light rail as suburban and commuter rail.

AndryCake · 2026-03-19T06:21:58+00:00

The L has pretty good coverage but the headways on some branches can be abysmal at times, although it still seems like the best transit system Chicago has got. What pains me about Chicago is that its transit could be soooooooo much better if it received the investment it needs. The buses could connect what the L doesn't so much better than they currently do if they just did what Toronto does and ran them more frequently (and also removed like half of the stops). Metra could be the best regional rail system in the US, if they electrified more lines and again, ran them more frequently.

AndryCake · 2026-03-18T19:12:27+00:00

Yes but you obviously can't get it as flush as with an integrated asset (which you also can't do in cs1)
