Ask HN: How close together are your bus stops?

85 points by superqwert 7y ago

In London UK, distances between bus stops are on average between 100 and 200m away from each other. I'm interested in finding out whether other cities in the world may have comparably short distances between bus stops and whether they have any datasets that could be used to calculate bus stop distance distributions.

fghtr 7y ago
I guess one could use openstreetmap data here, since they have pretty comprehensive coverage of bus stops, at least in Europe.
- ThePadawan 7y ago
  Also, national or regional data might be more complete. If you can speak enough German to navigate the download, you can e.g. find geodata of all bus stops in Zurich at https://maps.zh.ch/?topic=ZVVZH&showtab=ogddownload https://maps.zh.ch/?topic=ZVVZH&showtab=ogddownload (they will only deliver to email addresses, so I cannot link the actual data here).

    Zürich Tram and Bus distance (beeline) between stops of trips: Mean 199m Median 172m Min 14m (Zürich, Central <-> Zürich, Central Polybahn) Max 678m (Pfäffikon SZ, Bahnhof <-> Pfäffikon SZ, Schiffstation) According to a dataset of 1744 trips from https://data.stadt-zuerich.ch/dataset/vbz_fahrplandaten_gtfs https://data.stadt-zuerich.ch/dataset/vbz_fahrplandaten_gtfs
    - ThePadawan 7y ago
      Really cool, and thanks for finding a much more accessible data set than I managed to! For people non-familiar with Switzerland, though, it needs pointing out that Pfäffikon SZ is no longer in Zurich city nor Zurich state, but Schwyz (thus the SZ). It still comes up in that data set since it is served by ZVV, the Zurich transport authority. It would also be great to know how you group stops together as "the same stop, just different parts of it". I.e. Central vs. Central Polybahn - I would say these are actually colocated, just served by different lines (tram vs. furnicular).

"on average between 100 and 200m" is an imprecise statement. Where does this metric come from?
- superqwert 7y ago
  I haven't got the precise details yet - I've analysed about 20 bus routes so far and they have an average distance between stops of 128.4m. But till I scale up the analysis to all bus routes, I cannot say for certain that it is the London average.

200m is incredibly short. I'd say the average in Bangalore is around 700metres. It varies from 500m in dense parts of the city to 1.5km in the not so dense parts.
dintech 7y ago
It's obviously density related, even in London.

  It is also obvious that nobody on HN lives in the sticks. Or, if they do, then they drive and therefore have precisely zero interest in bus stops. My country dwelling parents have a bus stop outside their door. There is one bus per day - weekdays only - and that is only in one direction. This I find mind-boggling. A shopping trip would require an overnight stay in town and for a full circuit of the route to be completed. Somewhere there is a bus driver getting paid for that and a local authority that has mandated this service be put on.
  - ghaff 7y ago
    That does seem extreme. That said, a lot of small town and semi-rural public transit seems to operate at a level where it's marginally better than nothing but not much better for those who have alternatives. Around the exurbs/adjacent small city where I live, there is a small bus service that connects the Walmart, commuter rail, city center, etc. But I'd be pretty sure it's mostly used by those who can't drive.

https://en.wikipedia.org/wiki/General_Transit_Feed_Specification https://en.wikipedia.org/wiki/General_Transit_Feed_Specifica... is the most used file format. Public transport companies used to submit their information to Google Maps and similar (the 'G' used to stand for 'Google'). You can find those searching for 'GTFS <name of city>' in various open data portals. Alternatively OpenStreetMap is a huge global dataset. Buses are a small part of https://wiki.openstreetmap.org/wiki/Public_transport https://wiki.openstreetmap.org/wiki/Public_transport It's easy to extract bus stops https://wiki.openstreetmap.org/wiki/Overpass_API https://wiki.openstreetmap.org/wiki/Overpass_API (https://overpass-turbo.eu/ https://overpass-turbo.eu/) but you're probably interested in routes as well. It's a rabbit hole of complexity, e.g. a bus terminal is multiple bus stops, some buses skip stops based on time of day, weekday, season (school buses), some stops are just for drivers to take a break or refuel, direction of route matters. The transport view on https://www.openstreetmap.org/#map=16/21.3308/-157.8868&layers=T https://www.openstreetmap.org/#map=16/21.3308/-157.8868&laye... is a pretty nice visualization.

  I was involved in a project where we could identify Transit deserts (https://en.wikipedia.org/wiki/Transit_desert https://en.wikipedia.org/wiki/Transit_desert). Sadly the new administration cancelled this project. We were using GTFS data and US Census data to identify these. Quite interesting stuff. Perhaps the OP is interested in that as well.

London also has bus route 389 - the entire route is I think 1.5 miles, with something like a dozen stops
- zimpenfish 7y ago
  My rough calculations give it 15 stops for 2420m in direction 1 (avg 160m), and 2235m in direction 2 (avg 148m). Alas, it appears that route 631 has it beat - 1440m in direction 1 (avg 130m), 1751m in direction 2 (avg 134m) (although, peculiarly, the information in TfL's bus route download doesn't match what you get from the web site when you look up 631.)

In NYC, it depends heavily on the bus line. Some stop nearly every block (which can be as little as every 100m) whereas some have more widely-spaced stops. The buses here are notorious for running very slowly (and thus behind schedule), and one of the proposals to speed some some slow buses is to eliminate stops on lines where they are densely clustered. It's become a subject of considerable debate, as residents and in particular older and disabled people are usually against consolidation, whereas most others accept it as a necessary cost of improving service. The M14, which runs along 14th Street in Manhattan, is an example of where this is happening right now. Currently, the bus spends around 25% of its time standing in stations because it stops pretty much every block. There's a plan to eliminate some of its stops, but it's unclear whether it will succeed. Here's a good read on the subject: https://nyc.streetsblog.org/2019/04/19/never-stop-stopping-removing-bus-stops-isnt-easy-in-new-york-city-or-anywhere-else/ https://nyc.streetsblog.org/2019/04/19/never-stop-stopping-r...
- cletus 7y ago
  I was going to mention NYC too but in terms of the Subway, which is related. The "local" stops on a lot of Subway lines really shouldn't be there. I'm looking at you 18th Street, 28th Street, 50th Street and so on. 18th Street in particular is 4 blocks away (where 1 block = <1 minute walking) from 14th Street and the entrances to 14th Street will often extend up to 16th Street anyway (with the platform potentially right underneath). In the other direction 23rd Street is 5 blocks away. The Subway spends billions of dollars a year on power. Most of that power (for trains) is spent accelerating so every stop counts. I expect the same people who are against consolidation of bus stops are against consolidation of Subway stops. Honestly I personally have never taken a bus in NYC despite living here for nearly a decade. Distances in Manhattan are just so relatively short.

    50th seems a bit of an anomaly in your list? Otherwise there would be no stop between 42nd and Columbus Circle (I assume you mean the AC line?)

I live in Dublin and I take the bus everyday, is mad, I'm talking sometimes less than 50m. The stop in front of my house and the next one is only three houses away, Georgian style, so no mansions or huge houses. The transport in Dublin is horrible and is on top 5 of most expensive public transport systems. (No subway)

  If you live and work along the Luas it’s not so bad. But otherwise yeah it’s shite.
cafard 7y ago
In Washington, DC, the distance varies considerably, but 200m sounds about right for the average. WMATA does have a "next bus" service that I see people using.
- eli 7y ago
  Notably there are also several "MetroExtra" buses that run similar routes as popular bus lines but make about 1/3 as many stops and are therefore much faster. The NextBus service DC uses is clearly using a very naive algorithm that is often (consistently) too fast or slow. Some of the better apps modify it or add their own data.
  - cafard 7y ago
    Yes, WMATA has managed to move a lot of S9 buses up and down 16th St. NW at busy times of day. Judging from what I see, the S9 is efficient at moving such people as get on, less so in moving numbers of people. It is routine to see three mostly empty S9s go by a stop before a local bus (S1/S2/S4) arrives.

I live in London and I wouldn't say my local bus stops are spaced at 200m intervals. In Zone 2, sure. Not in the suburbs. Definitely density related.

Just measured the bus line I used to take from Edgewater, NJ into Manhattan (measured first stop in Edgwater to last stop in Weehawken), and it averages a little over 250m between stops, but they range from around 125m-700m between stops. One stop that always angered me was my bus stop to the next was 125m. Basically across the intersection, and there was almost always a single person over there, causing us to accelerate then stop.

In Freiburg/Germany (250k inhabitants), the mean distance between bus stops is 634m, more distant than those of the tram (453m). Freiburg has more trams (72) than busses (65) running on 44 km of rails and the sum of all bus routes is 160 km. [1] Trams run in short intervals and they are convenient when they're near, but switching from tram to bus carries a high time penalty two out of three times.

broz 7y ago
Here is Buenos Aires average is around 200-300m, which I personally find too short. I remember one time seeing two bus stops literally 20-25 meters away from each other. The bus needed to take left on a two lane road so it would circle the block, there was a bus stop just before entering the circle and just before leaving it. Driving distance was ~400m, but walking was a few steps.

For Switzerland, that distance sounds about right, tending more towards 100m (in major cities). There is bound to be a dataset somewhere: being a tiny country means that we map everything in great detail, and the government takes these topics quite seriously. Some links to get you started: https://www.geo.admin.ch/en/geo-information-switzerland/geodata-index-inspire.html https://www.geo.admin.ch/en/geo-information-switzerland/geod... https://www.geo.admin.ch/en/geo-information-switzerland/geodata-index-inspire/infrastructure-and-communication/transport-networks.html https://www.geo.admin.ch/en/geo-information-switzerland/geod...

Prague Per [0] (2001; in Czech), average distance between subway stations is 1038m, tram stops 500m and bus stops 698m. A related metric is walking distance from home to public transportation stop. Per [1] (2011; in Czech), most of people in the city need to walk less than 5 minutes to reach a stop. (There's a table with a breakdown by walking time and city part in chapter 7.) The same work cites average walking speed as 88.69 m/min, which gives you, for most inhabitants, <450m to reach a public transportation stop.

In Chicago, there are 1,536 route miles and 10,768 stops, suggesting average spacing is about 230 meters. I'm not sure if that double counts stops that serve multiple routes but it sounds about right.
- 3JPLW 7y ago
  Wow, that's almost exactly what I would have guessed. The block distance in Chicago is 1/8th mile (200m).
3JPLW 7y ago
In US cities, the densest lines will have one stop per "block" — and that's frequently a regular tenth or eighth of a mile (and more regular as you move towards the newer cities in the west). So you'll typically find minimum distances of 160m or 200m and then multiples of those for express lines or less dense areas.
a-saleh 7y ago
Depends on the line, heavily. There are some, especially in the center where distances around 300m are common, in the outskirt, you could ride for a kilometer or more between stops. I found a gis data for Prague public transport, so oyu might be able to query that: http://www.arcgis.com/home/webmap/viewer.html?url=http://mpp.iprpraha.cz/arcgis/rest/services/DOP/Linky_MHD_dnes/MapServer http://www.arcgis.com/home/webmap/viewer.html?url=http://mpp...
madprgmr 7y ago
I believe that while there are various guidelines and studies, it is typically up to the transit agency itself to determine stop density and locations. There are many companies that provide transit planning solutions which use GIS (with census data) to aid the process.

in the East Dallas Texas neighborhoods on major roads i would guess a little under a 1/4 mile. Probably a 5-10 min walk between them.
alkonaut 7y ago
Stockholm: Distances vary between different line types, e.g. the backbones lines 1..4 are a different type of backbone transit offering shorter travel times by having longer distances between stops (.5-1km) and shorter invervals between buses. Regular inner city buses have shorter distances. The free API is fantastic. I'd be willing to bet it's the most comprehensive public API for city public transport in the world (Happy to be proven wrong though!).

- heleninboodler 7y ago
  Feels roughly right. My only other observation on seattle buses is that some of the more ridiculous routes have stops every two blocks on an Ave (north-south), which works out to one every 200m or so, if you use the rule of thumb that the most uniform parts of the city have 16 blocks per mile.

In Amsterdam, and I guess many Dutch cities, the rule is that there must be a bus or tram stop within 400m from everywhere within the built-up area, so the maximum distance between stops is about 800m. The average will be lower of course.

In Seattle we have and are currently expanding a system of "RapidRide" buses. These appear to have an average stop distance of around 0.3 miles (~500 meters) Wikipedia claims that RapidRide routes have on average 40% fewer stops than the 'regular' line that they replaced, which would mean the 'regular' buses have stops about every 300 meters. Anecdotally, I lived in London for a few years and now live in Seattle, and I would say these number's all roughly match my experience. Seattle's stops are spaced quite a bit further apart, but Seattle is also much less dense :) see https://www.theurbanist.org/2018/03/26/rainier-rapidride-metro-seeks-streamlined-route-7/ https://www.theurbanist.org/2018/03/26/rainier-rapidride-met... and https://en.wikipedia.org/wiki/RapidRide https://en.wikipedia.org/wiki/RapidRide

As others have said varies greatly, but it seems most common around here (Beaverton / Hillsboro, Oregon) that they like to stop every block, sometimes on opposite sides on an intersection - which honestly baffles my mind but whatever.

Tokyo. The average distance between stops on major streets are about 200 to 400m here, except some busy areas. https://busmap.info/map/?q=%E6%9D%B1%E4%BA%AC%E9%83%BD%E6%96%B0%E5%AE%BF%E5%8C%BA https://busmap.info/map/?q=%E6%9D%B1%E4%BA%AC%E9%83%BD%E6%96... As you can imagine, buses are just as amazing as trains in Tokyo. They're sometimes running late, but only up to a few minutes. And often they come at the exact time. (There's a time table for every bus stop.) Most buses are accessible and there are a lot of elderly people using it. (Age 70 or older can get a free pass.) When there was a once-in-a-decade snowfall last year, they delayed about 10 minutes, and that was morning rush hours. Again, they do absolutely fantastic job here.

It depends on the bus! In my local city in China, for example: The BRT stops every 2km or so, and runs on dedicated lanes. The tram stops every 1km or so, no variation downtown or out of town. The 5 buses and 6* buses tend to be long distance within a metropolitan area and stop every 2-500m at pickup and destination, but can run 30km only stopping a couple of times at key pick-up/drop-off locations. Regularly numbered buses 1 though 70+ will stop every 500 meters or so, usually at each block. There's an app, PandaBus, that shows all of the routes and stops for every stop in most Chinese cities, and has live GPS of buses for several cities. I don't know where they get the data, I'm sure you can just ask them. In Hong Kong, numbering is a bit different and related to the city layout - basically HK is very dense in Central (Island) and Kowloon (peninsula) but due to coastal and mountainous topography very vast in the New Territories with 'new towns' being small urban pockets in the NT countryside. Take the, IIRC, 73. The 73 route runs from Tai Po to Kowloon. The 73X does this with lots of pick-ups in Tai Po, then expressway to Kowloon with a single stop in Shatin, that's about 80km. The 73K does the same route but doesn't take the expressway and stops at every conceivable point, expending the journey time by an hour or two. HK people please correct me as it's a long time since I was in HK. And HK also has the Toyota mini buses that have a single pickup point, drive like maniacs for 30-80km picking up speed downhill and losing momentum uphill, then drop off where you ask the driver. Good exciting ride, keep your eyes open!

In Indonesia, the city buses stop wherever it likes. In Jakarta though, the city managed bus (TransJakarta) have dedicated bus stop at about ~1km.
hema64b 7y ago
In China, big cities will set a distance of 500 meters between two bus stops. In my hometown which is a quite small city with 500k population, bus stops doesn't really work and every time you want to get on, just wave your hand. lol
matt_the_bass 7y ago
I have no statistics only anedata. In my old neighborhood in Providence RI bus stops we’re within shouting distance of the next stop. This was infuriating to me and a 2 mile bus ride to downtown could take 30-40 minutes. That is literally slower than my normal walking speed (~4 miles per hour). This duration was generally due to the number of stops not traffic. Maybe I’m a fast walker, but that still seems ridiculous.

When I visited Shanghai, I noticed that late at night when there are not many passengers, they will kick everybody off the train at a random stop. They do this with a few trains in a row until there are enough people waiting in the station to fill up a train to some acceptable level. I assume that the point of consolidating everybody into one train like this is so they can avoid wasting power decelerating/accelerating on a bunch of trains. I.e. just run all the empty ones to the terminus without stopping. It was a bit annoying whenever it happened to us, but I think this is a better system than getting rid of heavily used local stops entirely. Edit: As a reply explains, it's possible my description is slightly inaccurate.

Wowfunhappy 7y ago
Would this really save much efficiency versus the much less disruptive option of taking the trains out of commission (for the evening/morning/etc) when they get to the end of their route?
- umanwizard 7y ago
  I'm really not an expert on subways, so I don't know. But I can only assume that the people who run the Shanghai metro know what they're doing.
  - Wowfunhappy 7y ago
    Sorry, shouldn't have framed that as a question directed at you specifically. :)
seanmcdirmid 7y ago
Same thing happens in Beijing. Where they kick you off happens to be a subway depot where the train will sleep for the night (which isn't always at the terminus, e.g. if it is a loop line or at a remote junction); or it will simply express to the terminus after dumping all of its passengers. Usually, it's just the train's "time" to be off duty, they aren't actually looking at passenger densities or anything like that.

  Thanks for the clarification. Good chance that this is what's going on in Shanghai as well. I don't speak Chinese at all so I was pretty clueless.

> They do this with a few trains in a row until there are enough people waiting in the station to fill up a train to some acceptable level The "acceptable level" probably doesn't account for everyone getting a seat on the continuation train. This used to happen with buses in Wuhan 10 years ago. If two buses on the same route met up and each had only seated passengers, one would send its passengers to the other bus to stand for the rest of the journey. This was annoying because I would travel places at off-peak times just so I could get a seat. And of course, because this happens occasionally, it affects everyone using the Shanghai Metro because they all need to build in contingency time when planning a trip to get somewhere by a certain time for an appointment.

> The Subway spends billions of dollars a year on power. Most of that power (for trains) is spent accelerating so every stop counts. The entire MTA spends less than $500 million on electricity annually (which includes the subway, Long Island Railroad and MetroNorth commuter rail) of a roughly $17 billion dollar budget. Additionally, the 4.5 million people who use the 28th Street stop on the 1 line and the 6.7 million people who use the 28th Street on the 6 line and the 3.3 million people who use the 28th Street stop on the R/W lines politely disagree with you.

Moreover, if power becomes significant you can add regenerative breaking to regain a large fraction of energy (if they're not doing so already; maybe not because of the age of the trains).

  The London Underground definitely does that. Also in part because it reduces the heat output. The underground has been heatsoaking for decades and it’s hitting problematic temperature levels. This article is a great read: https://www.ianvisits.co.uk/blog/2017/06/10/cooling-the-tube-engineering-heat-out-of-the-underground/ https://www.ianvisits.co.uk/blog/2017/06/10/cooling-the-tube... Apparently about half of the heat generated in the tunnels is/was from braking. And the tunnel temperatures have risen from 14-30C since around 1908. Is a good read about the engineering challenges.

Annual ridership figures != people. For stops that are primarily commuter stops you have to divide by hundreds to get the actual person figure. 10k people using any given stop for one round trip twice per day is over 7M annual rides for that one stop. It's actually less than that for 18th St; using real data, the average daily ridership for is 8.6k. Compare with a station that is actually busy, like Union Square, which gets 109k daily ridership. Figures from https://graphics.wsj.com/table/NYRIDER_0420 https://graphics.wsj.com/table/NYRIDER_0420 So yeah, those people would be inconvenienced by having to walk a few more blocks, but way, way more people would experience greater convenience by having faster commutes along those very busy lines since they wouldn't need to make such close stops. There's a happy medium between too many stops and too few. Two stops within a quarter of a mile is way too many. You can imagine a subway system in which a north/south line stopped at literally every block; you'd probably still have more than a thousand daily riders at every stop, but that's no argument to keep every single one of those stops (or even worse, build them). The system performance would be terrible and it'd take forever to get anywhere. The same is still true when you have stops that are only four short blocks away from each other.

  I know how the ridership is measured. I’m not sure what your point was. It’s also not surprising that the busiest stations have 10x as many riders as those less busy. The four track system of the NYC Subway was its most important innovation, and it literally solved the problem your talking about. You don’t want all the stops? Walk to 14th and take the express.

    > I know how the ridership is measured. I’m not sure what your point was. Probably that it's inaccurate for you to say "the 4.5 million people who use the 28th Street stop" because that number is ridership, not people.

      C’mon -- that was a rhetorical flourish.
      - CydeWeys 7y ago
        A rhetorical flourish that conveniently made your argument appear much stronger than it actually was.

        That literally is the point of rhetoric.

There's an important distinction to be made here -- in Manhattan, in general, there are crosstown buses and buses which go uptown or downtown. And there are 2 kinds of 'block' in Manhattan, 'long blocks' are crosstown (east/west) and 'short blocks' which are north/south. Long blocks are irregular depending on where you are, and are typically much longer than short blocks ~3x. Most uptown and downtown buses offer limited and local service, with limited making far fewer stops. Most crosstown buses stop at every block. One more confounding factor is that about decade ago, the city replaced many crosstown buses with fewer but much larger articulated buses without realizing that the behavior of fewer larger buses is to make the average ride slower because of the time spent receiving passengers. To address that they created a new system for paying on certain buses involving buying a ticket before you board. But that is resulting in skyrocketing levels of fare evasion. Unintended consequences. The M14 is a special case right now because of limited service on the L train (which runs under 14th street) due to necessary repairs. The M14 is getting swamped with excess people who normally would prefer the subway.

Stupid question, probably. But I'm not American. Is a "block" just a continuous building with no gaps for a road or pavement? i.e. [#########building##########] [###### building###] [###] Would be 3 blocks? Or is a block only delineated by a road, but not a pavement? Or something else? Can you have "blocks" with a lot of detached houses, I would guess that yes you can? So that makes me think its blocks of possibly many buildings between roads?
- robrenaud 7y ago
  In American English, blocks are deliminated by roads and mostly used in dense urban environments, often where the blocks are rectangular.

    Etymology note: The word 'blockbuster' was coined by the press to describe the largest conventional bombs used by the RAF in WWII, because they could destroy a city block.

  A block (which, as you've pointed out is an ephemeral phrase), in NYC at least, is the space along a road from intersection to intersection. It thus usually doesn't count gaps between buildings or alleys or the like. Many of the long (east/west) blocks in Manhattan, for example, have pedestrian pass-throughs in the middle, but that doesn't count as a split in the block.

It's true that the M14 is special right now because it's currently serving riders of the L train, but the proposal to eliminate stops is part of the citywide Bus Action Plan that is being rolled out progressively by borough. Staten Island already redesigned its bus system, and IIRC the Bronx is next.
