For me its the cambridgeshire guided busway
>>
Bused and guidepilled
>>
>>1574382
Can this kind of structure be used on highways to avoid retards changing lanes all the time and ruining car traffic?
>>
>>1574382
>worst aspects of a tram combined with the worst aspects of a bus
>"h- here's your train. please clap."
the funniest part about these "guided busways" is the buses still have to go into road traffic for at least some of their journey. honestly it's such a fucking cop-out. just put it on rails, end of.
>>
>>1574399
no the bus needs little guidewheels
>>
>>1574430
There i much less infrastructure needed then a train tbf. The special guideway is so the county council doesnt just turn it into a road for normal traffic
>>
>>1574430
That's flexibility. A busway can handle steeper grades and tighter turns than rail can. I can see how it would be a preferable alternative to full LRVs. The costs are much lower, but you have to depend on the transit agency to build it right and not halfass it, because if done poorly it will just end up being an expensive meme.

I meant putting some of those concrete things in the middle of the highway so normie idiots don't switch lanes too much.

>>1574445
>>1574450
I was shilling a similar idea using tracks for less drag and more speed. Maybe there's some way to combine everything in a viable way.
How could the bus behave more similarly to a small HSR? How would the wheels work? And the tracks?
It is a hard question but it may result in something.
>>
>>1574598
Could (semi-)autonomous buses have insane speeds in dedicated lanes?
>>
>>1574598
>>1574601
You'd have to spend a lot of money to get buses safely up to those speeds for little gain. High speed buses don't exist because they're not economical
>>
>>1574605
That's part of the question. Buses need to be safe under very different conditions instead of just running forward in fixed tracks.

A few concrete slabs using existing buses (with already trained drivers and mechanics) are cheaper than a whole rail network.
>>
>>1574617
I was thinking about changes like stiffening the suspension and making the tires more rigid on demand, ...
>>
>>1574598
Bus speed can be improved, but really isn't the strength of buses, just like flexibility, value, utility, agility, and future scalability aren't the strength of trains.

there would be extreme stress to the guide wheels, heavy hunting oscillation and rolling resistance.
For speeds between 100 and 230 mph steel wheels and rail are unbeatable.
>>
>>1574932
I would neither honk nor reduce throttle

Would be based if the busses weren't shit and on time.

The busses were fun to draft behind tho.

Replacing guide wheels with sensors and semi-auto pilot and this:
>>1574630
Maybe are possibilities. Still it's far from the same thing.
>>
>>1575821
Sensors, GPS and maps.
>>
>>1575821
>>1575822
There are optically- and magnetically-guided busways, much better than GPS
>>
>>1575829
You need to decide if you are in a fast busway or not in case you have automations that depend on it. And you can use shitty proximity sensors and other trivial onboard equipment to fine tune the bus position instead of relying on some complex system to do so.

Why do people feel the need to reinvent shit? Put down regular buss lanes or rails you fucking new age cunts.

why not just make bus-only roads?

Not much of an argument

>why not just make bus-only roads?
That's what a busway is
>>
>>1574382
I personally quite like the O-Bahn.
>>
>>1576442
They're taking the lowest common denominator into account. The "rails" are too wide for a car to drive onto.

It's cheaper to install, easier to maintain and integrates into the existing road network.
>>
>>1574382
is this a type of BRT?
>>
>>1574598
>I meant putting some of those concrete things in the middle of the highway so normie idiots don't switch lanes too much.
some carpool lanes in cali have this. you can only enter and exit every few miles or so, skipping a few offramps at a time. its double yellow lines so you can exit in case of emergency but risk a ticket if caught doing it without reason

what an absolute waste of space and money

You could put the guideway in the centre of the highway, and basically separate it from car traffic. It would be similar to having a train line inside a highway, but instead it's a bus. Unless you're talking about something like pic related but with guideways, which would limit how much cagers could weave through bus lanes.

They have guidewheels, pic related.

If it reassures you any further, there haven't been any major accidents in 35 years of operation. The main issues are drunk retards trying to drive their cars onto the track and then getting stuck.

Essen, Germany, had a guided busway that used dual-mode buses and shared part of the busway with a tram line into an underground station. From what I can gather, it fell out of use shortly after reunification.
>>
>>1581381
From what I understand the wheels aren't really used when you're on the track it's more for just guiding it into the track properly at the start of it.
>>
>>1574632
Horsepower and gearing is also a limiting factor to this. Busses are heavy, they need a lot of horsepower to drive fast. On a diesel horsepower = fuel. Urban busses are already fucking savage on fuel (like 2km/litre on some double decks) so making them run at high speeds would just make them use a lot of fuel and for what gain?
>>
>>1574632
>>1583927
So you are saying that the BR Pacer was the best combination of the busses speed/carrying capacity and the route flexibility/adaptability of the train?
>>
>>1583927
So why not do what SF did in the 80s and electrify the busses.

I think Utah did something similar with a bus on their University Campus, only instead of using a catenary wire, the bus has a bank of supercaps and some backup batteries, and gets quick charges from induction pads beneath the route.

Trolleybusses. In Arnhem, the Netherlands.

A bus powered by overhead electric cables. Great. Of course the bumpercars at the fairground get their power from electrified chickenwire overhead.

You got to wonder if instead of rechargeable e-cars it wouldn't be an option to use that idea all over the city

why not just use rail?

110db alarm going off if you brake when going any faster than 40mph will solve traffic problems.
>>
>>1583936
Yes.

Imagine building this shit when you could have a dedicated bus lane and camera enforcement to get sweet fucking penalty revenue from all the drivers who try to use it. Local gov is retarded and too ethical.

looks much better than the Austin bus lanes, confusing to UT students and tourist so it get jacked up at times. APD bike cops pull cars over, they can squirt thru traffic. sneak up on ya

I might be moving to Cambridge next year and will probably be using this regularly, I've not been on it before though.

$5 trying to push for this would suddenly instill a sense of local political activism into people who could never be bothered to vote in anything but federal elections before, if they voted at all.

You'd actually be getting in the way of their daily liberty to use a multi-ton vehicle as an expression of their own mentality and seeming self-interest. You'd be robbing them of a core coping mechanism in their life for the sake of other people they couldn't care less about when on the road. You'd get the political equivalent of "fuck you fuck you fuck you fuc-".

Still better than a bus without its own ROW

>>1574399
Would be better to have self driving "traffic mode" that links the cars and uses ai to move the traffic along
