Shouldn't we be switching buses with light railway?
Shouldn't we be switching buses with light railway?
Even if you think what you would say is obvious, please add. This is genuinely something I think makes sense regarding local bus routes given the longevity of light rail and how infrequently routes change, but I also suffer from confirmation bias, so I'm hoping for reasons this would be a terrible idea but obviously would prefer reasons it would be an even more amazing idea than I thought.
The big benefit of light rail is you can make trains longer than buses, and fit more people. So if your system has outgrown buses, then you should move to rail.
But transit systems should always be trying to maximize frequency, because the more frequently a train or bus comes, the more convenient it is for riders. So if a bus fits 30 people and a train fits 90 and you’re trying to make a decision between providing a bus service every 10 minutes or a train service every 30 minutes, the bus service is the better option.
Different modes work best for different passenger demands, and you should use the right one for the number of passengers you’ve got. Overbuilding is expensive, and if you spend too much building out a network and the don’t have enough for operating expenses then you’ve got to reduce service levels.
There's pros and cons of buses vs trams.
The pros that I'd slate for trams do include a better ride, more throughput (carries more people), wholly electric, are more durable than busses, and very quiet in general. People in this thread have noted most of these already, but the one that I feel is very overlooked is that they're a commitment by the city along their routes. Many people will note that busses have advantages because their routes are easier to change. While true, I feel it's actually worth considering that this is also a negative from the perspective of anyone who wants to invest in property that relies upon the bus route. If you can't trust that the city won't just up and move the bus stop away from your shop or apartment complex, you'll be more reluctant to invest in the location. Trams are indeed much harder to change, but that's actually a good thing from the perspective of investors. If I'm going to invest millions of dollars in an apartment complex, would I rather do it next to a bus stop that might not be there next year, or a tram stop that's really hard to move away?
Another advantage is how well the tram integrates with pedestrians. Busses are only as accurate as the driver. As a pedestrian, I have to pay attention to every bus just as I would cars on the road. They're dangerous to be around. Trams are much more predictable (see: rails) so they can be used in/around public squares, markets, and along walkways with more safety for the people walking nearby. The rails themselves also show you where the transit is. Bus routes are invisible except for the stops and when you see the busses go by. When I'm walking in a city that has railed transit, I love seeing the rails because I know that I likely follow them to the next stop, and that by stops there will be shops, stores, and interesting places. They're a guide to the best places in the city even if I can't see the tram at that exact moment.
Trams are also usually larger inside. There's more room for wheelchairs, bicycles, and other mobility aids. They're a better conveyance for people who need the room. Those same people also need to pick where they live carefully so that their transit won't up and change on them. Having the bus stop move a block away could be a huge hurdle for their daily mobility needs.
Railed transit provides a permanency and a more equitable transit solution for a city. It's not the right solution in every instance, but as a city grows it needs to start investing in railed transit. Those rails provide the bones of where growth will centralize around giving the city focus and then identity as neighborhoods grow around tram/light rail stops. There's a power to railed transit that busses just don't provide in their stability, visibility, and statement of commitment to the longevity that a city should be investing in.
Also, look up grassy tram lines. That's peak urbanism!
Light rail is infinitely more expensive to construct and it only takes one delay/accident and all subsequent trains after cause a log jam...vs a bus which can route around it.
A better solution uses corridors dedicated to buses that are electric powered.
Something like this was done in Colombia with these routes being connected by ground hubs, similar to subway stations.
Probably biassed as I'm a bus driver but the city I'm in has a tram and it's fantastic until one gets blocked or broken. Benefit of busses is they can detour if needed, and if one breaks it doesn't (always) block the entire route
edit: extra annoying when they break down and I have to carry a tram load of passengers on one double decker bus
Busses have their uses. Lots of commentor have mentioned the flexibility in setting up / changing routes. But there's also the flexibility in sizes. You can start a line with a large van or small mini bus and your only overhead is the driver. From there you can scale that up according to demand up to frequently run articulated busses. Meanwhile your minimum investment for tram includes at the very least a not inexpensive track installation.
Don't get me wrong. If you have the passenger volume that investment definitely pays off. But I don't like this unnecessary competition between two modes of transport that can be very complimentary to each other and are both better than individual cars.
With the caveat that this only applies to my city, San Francisco... I prefer buses. SF horribly mismanages its "trams"* where they run at ground level through the streets. They must follow all stop signs and traffic rules. They don't even get signal priority. So it's a quite jarring experience to get into a train underground, exit the tunnel to the street, and begin stopping every block and waiting at red lights.
Fact of the matter is that, if you're going to be treated like a car, it's better to be more maneuverable as a bus. Buses can avoid double parked cars, and have a fighting chance of squeezing through a gridlocked intersection. With a bus lane, they can use it but they don't have to, where's trams are trapped in a traffic lane (frequently the centermost lane) while idiots make (frequently illegal) left turns.
* Muni light rail - K, J, L, M, N, T, F
Yes but it makes economic sense only on the routes with top demand that pass through the center or CBDs or other high traffic areas
When did we stop calling them trams?
The busiest core routes should be served with light rail, allowing an efficient high-frequency service for the most common journeys, and most parts of a city should ideally have some kind of connection to that rail system within a kilometre or two. But you can't just put rails and stations literally everywhere, so buses (or trolleybuses with batteries if you're so inclined) remain useful for less common routes, gaps between stations, the neighbouring areas of rail routes or last-mile connections from light rail to within a short walk of a person's final destination.
Buses are also necessary as a fallback during maintenance or unforeseen closures on the rail network. Even if it's just a temporary station closure, that one station will likely be the only one in walking distance for quite a few people (especially if we're talking about an interurban network where a small, outlying town or village might only have one station connecting it to the rest of its metro area), whereas that same area could have several bus stops, giving pretty much everyone there a way to continue getting around, perhaps even to get a bus to neighbouring stations.
And bus routes don't change that infrequently. Certainly, not infrequently enough that you'd want to tie them to placing or removing fixed infrastructure like tracks or wires. Diversions also happen sometimes. All of this isn't to argue against light rail, but to argue for a comprehensive multi-modal vision of public transport. Let passengers use the right combination of services for their particular journey's needs.
Shouldn't we be switching buses with light railway?
Yes
Trams are the cosiest things to sit in. I enjoy being half asleep in the morning and just look at all the people being busy. Wish my town had some more grassy lines, but they don't lack on where you can go.
(edit: I want to add that I am also happy with the buses here, don't think there is a reason to be either or and rather focus on reducing cars in town and in its suburbs. Obviously easier to do for smaller towns).
It depends on the type of light rail.
Here in my city the trams share some of the roads with regular traffic, which not only means they can get caught in traffic (though they have priority where possible), but it also means the rails become a real tripping hazard for cyclists (over 800 injuries since 2015 at the last count). There's been an active campaign to introduce more safety measures but the council has been reluctant to do anything about it.
The tramlines are such a well-known hazard to locals that they actually put people off from cycling, which is surely counter-productive.
I'm surprised nobody pointed out that tyres are extremely polluting:
https://www.theguardian.com/environment/2022/jun/03/car-tyres-produce-more-particle-pollution-than-exhausts-tests-showCityNerd posted a really good video on this topic a few months ago. https://youtu.be/H6UD9h3hEdk
His videos are primarily US-focused, but I believe this one applies for pretty much any country.
We need a whole host of public transit options that are best suited for each circumstance of a given area. I want public transit so smooth that even if you tried getting lost you end up where you wanted to go with no clue on how it happened. (last bit is an over exaggeration since i don't know how feasible that actually is lol)
My pet conspiracy theory is that most bus routes are a false compromise sold to voters.
Depends on the road layout; if it's a long straight road then light railway makes sense. It's less maintenance, easier to operate, can move unhindered because it doesn't get stuck in traffic (edit: provided they don't share the roads).
For spaghetti road layouts though, I don't see the benefit, but I could be wrong since I'm no expert.
I was initially conceiving this point as a venn diagram, but I guess it works like this as well.
(fuck cars/fuck bikes)I would think adding railways to places would take a long time, cost a ton of money, and without enough population it doesn't make sense. I don't know what specific area of the world you are thinking, but most of the world is pretty empty outside of major cities, and most of them probably do have rail service.
I have old rail running right behind my house that people always want to start using again. It's in pretty rough shape so the eyes is it's easy to expensive to get it up to spec and the amount of public interest is too low that it become unfeasable.
Buses on the other hand, can get plopped down instantly wherever they will fit on existing infrastructure. They can go where the demands is. You can have a spare one on the lot. I'd think it's easier to become a bus driver than a conductor. And ultimately if you need more buses, just but another, and if you decide to scrap the program, sell the bus and you have no useless remaining infrastructure.
Overall I'd it had the choice to take a bus from A to B or rail, I'd probably choose rail I'd the pickups and drop s were the same, but again, that's also much harder to do with a train. There's room for both, but here I think trains make more sense for longer distances and buses for local.
Another problem with light rail would be mountains. Trains don't like those. On the other hand, cable-cars and cog railway exists and seem to be viable solutions. The city of Lyon even has both and since the cog railway starts on a flat terrain, it is able to switch between both.
Sorry, we don't have many trams in London, is the issue overly thin wheels like that of racers?
If you design your bus system like a light rail system without rails, you magically get most of the benefits for far less cost: https://youtu.be/fh1IaVmu3Y8
