A really stupid thing in the world of bus stops is the bus stop that is placed immediately before an intersection with a traffic light. The light is green, but someone wants to get on or off, so the bus has to stop at that stop. Then just as it is about to pull out, the light goes yellow.

I think the main idea behind it is that it allows buses to queue up if many arrive at once without blocking the intersection

I'm in Europe and haven't experienced the US public transportation system, so I can't offer an opinion, but in my country the number of stops seem to have a negligible effect on the average speed.

Most of the slowness comes from traffic. Where there are bus lanes, the bus can even be as fast or faster than a car. Some of our trams stop every 300 meters or so, but since they have dedicated lanes, they are pretty quick. Some of the stops are at intersections where a car would also wait. When the timing is right, and most often it is, the trams don't waste more time than would've been wasted just waiting for you turn at the intersection.

Where there is a bike lane parallel to the cars, busses and trams, an electric bike with 35-40 km/h will usually be the the fastest method of transportation, especially if you cross on reds when there's 0% chance of a car hitting you. I'm talking about a busy main street with lots of lights and traffic, not a highway, of course.

Busses with no dedicated bus lanes are slower than cars, because cars are quicker to maneuver and accelerate when needed. I think if out city made the busses (and trams, and trolleys) 2-3 times more frequent, most people would use them. It would be a difference of driving in traffic for 1 hour vs sitting in a bus reading something (or doom scrolling) for 1 hour and 10 minutes. Shorter stops means less walking, so it would incentivize people to use the public transportation more. The benefits are obvious - less traffic overall, less pollution, less energy used, less road rage, more time to chill, and so on.

How is this not a solved problem already?

I'd assume people managing routes do this sort of analysis already. If they don't then sure give this a go in a few places and measure the results. Sounds like its worth a short if we're so off from EU.

People complain to their local governments + sue transit authorities that try to do this because they like having a stop right outside their house

We're talking about the US here; they're very good at ignoring solutions to solved problems. See city planning, traffic design, healthcare, zoning, etc. If it's not invented in the US, it can't possibly work there, they claim.

"Cheap" how? I have a friend who works on Seattle's bus planning. Removing a stop is a _lot_ of political work. When an elderly person depends on that bus stop being within a block so they can get to their doctor, and you're proposing to move it six blocks further away, that's essentially a _political_ cost.

It might better in the system throughput, and those benefits may even outweigh the misery put on that one person. But in the US, we largely sort that out by using cool-down times, hearings, and "community input."

Net result, according to my friend at least, is that bus stops feel _very_ sticky and hard to change.

I think the article means 'cheap' as in it doesn't really require any new/expensive infrastructure and could theoretically be done overnight.

Though, as you mention it's a big political ask (which is unfortunate).

Checking how long would it be for me to get to work in Google maps Car 25min Bus 1h.50min It's so crazy the difference, in other countries it only doubles but in the us is 4x the time.

I'm for all for less bus stops, but how do you make it equitable for people who can't walk longer distances if they are disabled or have an underlying health condition? Run a separate paratransit line?

In European cities this is mitigated by having low-floor buses and stops with level boarding to support mobility scooters and wheelchairs. There are also dedicated taxis available for people with disabilities (possibly subsidised). Over a long term this is also a self-regulating problem. Elderly people and services/businesses for them take into account availability of public transit when choosing properties.

Buses are mass transit. The real goal isn't serving poor people, but moving people with higher throughput than it's possible by cars individually (a single bus fits ~50 people). If you make bus lines slow and fail to attract significant numbers of passengers by forcing buses to serve every whatabout case, you're making them fail at their primary goal.

You can't make half-pregnant public transit. If you have a congested city, and just add nearly empty buses sitting in traffic and blocking lanes at every intersection, it will be strictly worse for everyone. OTOH if you can make buses an attractive option, then each bus can take 30+ cars off the road, leaving room for dedicated bus lanes, more buses, resulting in faster and more regular service.

"If you have a congested city"

I would agree with and extend your remarks that we also have problems where traffic patterns and geography don't match political boundaries and transit is traditionally locally run and locally budgeted.

So in the USA you end in scenarios where it takes 20 minutes to drive 20 miles but a bus would take four legs with three transfers across three separate city bus companies, figure at least three hours each way. And again, as per your "mass transit" you can't expect taxpayers in my city to provide a special bus run into my neighboring adjacent city much less the city next to that one.

This results in people being very happy indeed to pay the financial and environmental costs of car ownership to avoid sitting in a bus for six hours of daily commute.

There are also interesting social issues; if you're late its a personal failing, even if you take mass transit. I recall a friend at work getting fired because the bus was late too many times. Oh well, should have bought a car. The feeling of not being in control is further worse due to crime rates. No one will sneak up on my wife and stab her in the neck in her car, but it certainly happens on buses and no one cares if it happens depending on local race relations. None of the other passengers on the bus even cared, for racial reasons. Its pretty messed up here.

Its easy for the public in general to advise others to do inconvenient or career ending or life threatening activities, to "save the planet" or whatever, but I wouldn't do it, and I'd certainly never let my wife or kids do it, so we own cars and avoid public transit at all costs. Not taking that advice as been pretty nice so far.

The answer is to keep the same number of stops but run two or more vehicles simultaneously. Or open more doors. Or expedite fares.

The authors get mixed up equating count of marked stops with dwell time. Running leapfrogging vehicles , or numerous other strategies, reduces dwell time because one boards passengers and the other disembarks at any given stop or vice versa.

In fact, I’d argue bus fare gates, steps, 1-door loading and traffic signal/stop interactions are far more significant than stop count.

Then you end up with buses piling up at stops, which slows everything down even more.

How exactly does that help? If you’re suggesting every bus go to alternate stops leapfrogging each one in the middle then that will cause a lot of confusion especially for tourist heavy cities.

In 2022 according to the transit system annual report, the suburban quarter million person city I live in has ten routes and operates about 12 hours per day and per the annual report average weekday service consumed is 1556 UPT, so 1556 people step aboard the system and toss coins in the fare jar or pay with the app. UPT means they're not tracking transfers and essentially 100% of trips require a transfer so the real number of people served daily is closer to 775 than to 1550, but we'll run the optimistic numbers. Each of the ten hourly routes is about 4 miles long. So the overall system drives 12 hours * 10 routes * 4 miles * 5280 feet/mile = 2.5 million feet per day and divide that by 1556 passengers per day that's a pax every 1628 feet driven on an average day.

So if we had a bus stop every 800 feet, on average half the stops would be empty and passed by. If that high level of use is causing too much congestion and slow down at stops, if we had two buses running out of phase, pax arrive at the same rate, so we'd pick up a pax every 3000+ feet driven. So if we had bus stops every 500 feet to keep people happy, on average the bus would drive right by about 5 out of 6 empty stops, which seems reasonable and would not result in unusual delays or congestion. Also the bus would pass by every half hour not every hour, which would probably increase ridership a lot.

So if the only labor expense were the $23/hr driver, and we pay 10 drivers on 10 routes, to drive twelve times, thats $23/hr * 10 routes * 12 hours if everything except driver labor were free that means we spend $2760 per day to transport 1556 people, or about $1.77 per trip (assuming diesel is free, buses never wear out, etc). If we doubled the number of bus that would be $5520 of driver labor to move 1556 people per day or $3.55 cost per pax trip. On one hand the actual annual total "OE per UPT" counting weekends and maint and office people and dispatchers etc, according to the annual report is $13.94, so an extra $1.77 would seem cheap, but the bus does not run for free and the total expense of doubling the runs might cost as much as an extra $14 per pax trip.

The costs don't really matter, if the taxpayers want it as a luxury bragging feature of the city. Everyone wants everyone else to use it even though no one would be caught dead actually using it. My point being that adult fare is $2 but adults don't ride its mostly elderly and disabled at the $1 fare, so a profit (loss) ratio of (28 - 1)/28 with two buses per route isn't much worse than (14 - 1)/14 with one bus per route.

Maybe another way to look at the analysis is in my city if the stops are more than 1600 feet apart there will be multiple people per stop and that would "slow things down" whereas a small fraction like 400 feet would mean the bus mostly just speeds by.

No one can seem to explain why we can't have infinite bus stops. How about every stop sign is a bus stop? The bus has to stop anyway. Artificial scarcity to drive down ridership, I suppose.

This resonates with me. I used to live in a medium-sized US city which prided itself on its public transit. The buses were SO slow, and it's because they would sometimes literally stop every two blocks on a major through street. (This particular city has the smallest "block size" in the US, so it was extra ridiculous). It was infuriating. I would gladly walk twice as far to find the first stop if it meant the bus stopped half as much once I'm on it.

Bringing up accessibility concerns for people who can't walk as far is well-meant, but seems contrived. There's no guarantee that accessible housing is available near the existing stops anyway, and with the cost savings from having fewer stops (and windfall from increased ridership due to the bus becoming a faster option), bus lines could even be expanded, allowing more people to live near a bus line in general. Perhaps it would balance out?

Many transit services also offer smaller shuttles that can go directly to the homes of people with disabilities, so putting that responsibility on buses alone seems ineffective. I think the author is on to something here.

When I rode the city bus as a teen in South Bend, IN, in the 80s, there were some designated bus stops. But buses worked on a hail model anyway. You could be on any corner on the route, and as the bus approached, you'd just stick up your arm and it would stop. It was really efficient. But I suppose that works best in a small city like South Bend.

Some areas around Amsterdam have a two-tier bus system, with regular buses with regularly spaced stops, and a network of fast long-distance buses with far less stops and dedicated lanes over their entire trip. They have proven to be incredibly reliable; during the occasional day of terrible weather when trains leave people stranded, these buses still manage to get everybody home in a reasonable time.

Although long ago now, When I moved from Denmark to Seattle and tried to use the bus, it was immediately apparent that there’s at least double, maybe triple, the number of stops in Seattle’s Metro as there are in the same distance in Copenhagen. At the time I remember thinking that the average Seattle trip would be SO much faster if the number of stops were dramatically reduced.

The average Seattle trip would be so much faster if bus coverage and frequency were increased, and they got dedicated travel lanes.

The reason 'Race the 8' is an event isn't because there are too many bus stops on Denny, it's because all the cars cause traffic to slow to a crawl for 6 hours of the day.

My observation at the time was mostly in Magnolia to the Belltown area and the place I thought had way too many stops was in the Magnolia neighborhood, almost per block and it seemed a terrible waste. Plus the buses themselves seemed to resent being stopped and started so much—they rattled and groaned and squeaked.
