How about 2 more lanes?

I think 3 more will be plenty.

Think of it like trickle down economics. If it hasn’t worked yet, you just need to make sure that the fat cats on top are fed so forcefully and so fast that something starts trickling down eventually.

Just keep going. We will tell you when to stop.

Elon:

Guys, I think I’ve got it… What if we built another lane but, you know, under the ground, like a tunnel.

scrubbles ,
@scrubbles@poptalk.scrubbles.tech avatar

He seemed to casually ignore that at the end of the tunnel was still the concept of an offramp with a 25mph street that everyone was funneling to.

Of course he never planned on building it anyway. It was all just to distract from California High Speed Rail, because that directly gets in his way of selling more cars.

bobs_monkey ,

because that directly gets in his way of selling more cars.

Which is stupid in itself, because the entire goal of the CA HSR project is to link long distance corridors, not putzing around town like most do with a Tesla.

Wirlocke ,

In fact I think there’s a missed opportunity for EVs to partner with long distance public transit.

The main limitations of electric cars is distance, but if people knew they could go across the state or several states comfortably without their car, they might be more willing to take a electric car for city driving.

KillerTofu ,

We have ferries. What if we could combine the efficiency of train and the convenience of ferries? People could just drive their own car on a train car of some kind and be shuttled to a destination and then drive off?

Wirlocke ,

I’ve seen those trucks with a bunch of cars packed on top, something like that (minus truck) could totally fit in a train cargo container.

Without looking deeper it’s probably cost prohibitive. Looking at long train rides cost a thousand dollars and takes 3-4 days, might as well just fly at that point.

zalgotext ,

Yeah putting cars on trains is the opposite of a solution lol. All that cargo space used on a car probably just ends up driving the cost of the train ticket up for everyone. If you really need a car, rent one at your destination, like you would when flying.

that’s been done in europe since I think the 1930s

I’m sure the idea is suppressed on over in Merica. Glad it’s not an original thought!

mondoman712 ,

Just to be pedantic, the dumb car tunnels (or Loop), are the weird thing elon “invented” to “solve” traffic and reduce competition for his cars for urban transport. This eventually became one tunnel in LA to get between elon’s house and office, and the dumb taxi tunnel in Las Vegas.

The hyperloop, where elon “invented” the vacuum train, is a separate thing that exists to distract from CAHSR, and elon didn’t want to work on himself because “he’s too busy”, and not because it’s effectively just a scam and won’t work, and most of the companies that started up to develop it have since gone bust.

Annoyed_Crabby ,

I recently watched a video about autonomous car and the dude argue the tech isn’t here yet, but it will work if we build a lane just for autonomous car and put every autonomous car on that lane.

So many people commuting to jobs that could easily be done from home nowadays

I work in the freight industry in a position I can’t do from home but when the whole work from home thing was in full swing I didn’t get stuck in traffic except a few times when the local drawbridge went up

conorab ,

This is the most infuriating part. The best solution to these issues is to remove the need to move in the first place, and WFH for the people that want it and who can do it removes a huge amount of traffic with comparably little cost (company laptop, a screen and maybe a desk and chair, many of which could just be taken from the office).

psud ,

You know what would work just as well, but without isolating people?

Mixed zoning and mass rapid transit

Let people work walking distance to their home, give those who need to go somewhere a way of going there quicker than traffic

It’d also be good to mandate easy availability of work from home for anyone in a job where that is practical

Hammocks4All ,

I once heard of an experiment in economics that offers insight into this.

Say you have 100 people. You give each of them one of two choices:

A : you get $40 unconditionally B: you get $70 - n, where n is the number of people who choose B

You end up getting, on average across experiments, n = 30.

If you move the numbers around (i.e, the $40 and the $70), you keep getting, on average, a number of people choosing B so that B pays out the same as A.

I think the interpretation is that people can be categorized by the amount of risk they’re willing to take. If you make B less risky, you’ll get a new category of people. If you make it more risky, you’ll lose categories.

Applied to traffic, opening up a new lane brings in new categories of people who are willing to risk the traffic.

Or something. Sorry I don’t remember it better and am too lazy to look it up. Pretty pretty cool though.

Eigerloft ,

It’s called “Induced Demand”.

As a road widening project is completed, traffic is alleviated for a short amount of time. Then as time passes word spreads, or more people move to the city, or kids get older and get their driver’s licences. More and more people know this widened road is the fastest route, so more people take it, thus undoing the improvement. Then the cycle starts again - either with the same road being widened again, or another one a block over, on and on until the world is covered in asphalt.

The solution is to make alternative transit more appealing than cars. Bikes and public transit already have significant financial benefits, but lack infrastructure to make it more viable in North America. Busses get stuck in traffic, bikes are forced to share lane space with cars or sidewalks with pedestrians.

corgi ,

How is alternative transit the solution? Cities that have public transportation still have traffic jams.

There was an English traffic engineer that predicted that avg speed in central London will always be like 9mph. No matter how many lanes or public transit options you add. If there is no traffic, people will take cars until traffic jams are unbearable to give up. Then the system finds equilibrium.

Eigerloft ,

The key is public transit that doesn’t suck. For the last 100 years the car and oil/gas industries have spent billions of dollars undermining public transit.

Dedicated transit lanes, subways, light rail, protected bike lanes all make cars less appealing to those that want to use them.

a_wild_mimic_appears ,

Yeah, one of the best examples of this is the Vienna public transit network. About 1000 vehicles (bus, tram, light rail, subway) in service at rush hour, a daily total distance of over 200000km traveled, more year-long ticket owners than car owners in the city, and about 2 million “travels” per day, which is about 30% of all traveling done over the city (including pedestrian and bike traffic)

If that traffic would be routed only by car, the city would be a giant parking space; to compare, one subway train carries about 900 people in rush hour, which replaces 790 cars (avg 1,14 persons per car here). the subway interval in the rush hour is about 4 minutes. i live at one of the subway final destinations, which is on one of the far ends of the city - and i can be at the other side of town in about 25 minutes.

And constructing and running a public transit network is a pretty nice boost to the local economy, creates a whole lot of jobs. sounds like something a lot of us cities could make use of.

Mixed traffic works here, it allows mobility for all social classes (yearlong tickets cost 365€, so about 400$ incl. taxes), nearly all stations are barrier free.

grue , (edited )

The key is that both adding car lanes and adding alternatives like transit are subject to induced demand, but the consequences of it are different for transit than for cars. Not only is the limit of the added capacity much, much higher for a train than it is for a car lane, adding more traffic to the lane up to that limit makes the performance worse and worse (increasing congestion), while adding more transit ridership up to its limit makes the performance better and better (increasing train frequency and therefore reducing wait times).

Similarly, induced demand for walking and biking is a good thing because more people doing those things improves public health, doesn’t pollute like cars do, and takes up much less space.

So it’s not that induced demand is bad, it’s that inducing demand for cars, specifically is bad.

driving_crooner ,
@driving_crooner@lemmy.eco.br avatar

Public transit that share lines with cars are always going to be worst that cars, but if you add exclusive lanes for Public transit they go smooth as hell. This is why metros are usually the best option on cities with good metro infrastructure.

Skullgrid ,
@Skullgrid@lemmy.world avatar

having lived in cities with amazing metro, ok metro, no metro and towns with shitty train access and great train access…

this is 150% true. Having an underground station near your house makes the entire city 30 min away, using buses or horribly interconnected trains makes things 1 to 2 hours away.

Even living outside the city, having a direct rail to the nearest metropolitan center take an hour increased quality of life for me by a fuckload.

BastingChemina ,

The goal for alternative transit is not to remove traffic jam, it’s to transport people.

9mph is slower than a bike, it fits with my experience. When living in a city (in Europe, it might be different in the US) my feeling was always that bike was the fastest, public transport a bit slower but more comfortable (mainly protected from the elements and car drivers) and lastly car was the slowest and more stressful.

EldritchFeminity ,

There will always be traffic, but public transportation allows for a higher throughput for the same speed and total surface area of the roads.

Let’s be generous and assume that every car has 2 people in it (the truth is that the vast majority of cars, especially in the US, only have 1 person in them). Now imagine 15 cars vs. 30 bicycles. If we figure that you can comfortably fit 3 bikes in the same space as 1 car, you’re looking at 150% throughput for the bikes compared to the cars at the same speed. Give them their own dedicated, separate infrastructure, and they can probably go faster than traffic while also removing the danger of bikes and cars sharing the road. If you figure buses can fit 20 people in the space of 2 car lengths, you’re looking at 10x the throughput.

And that’s not even getting into transportation that doesn’t use the roads. The Boston T is a perfect example of this. Despite its notoriety for constant failures due to poor maintenance, and only being half the size it was 100 years ago, the T is considered to be the 3rd best public transportation network in the US. Why? Because the average commute time is about half the national average at roughly half an hour, and a full 50% of Boston’s commuters use the T every day. That’s half as many cars in traffic every day than if the T didn’t exist. Could you imagine if Boston, notorious for its bad roads and heavy traffic, suddenly had twice as many cars driving on its streets?

EldritchFeminity ,

I heard a city planner talk about why adding a new lane doesn’t help, and the term they use is “induced demand.”

Basically, people are going to take the route that they consider the most convenient, and that usually comes down to time and effort. Traffic hurts both by taking more time and being more stressful to deal with. When you add a new lane to a road, people think that the traffic will be easier there, so they take that route instead of their normal one. So you’re just adding more cars to the traffic that match or exceed the throughput of your new lane, basically putting you back at square one but a few billion dollars more poor.

You’ve essentially added a single lane one-way road to help ease traffic across the entire city.

Xavienth ,

If you make driving easier than transit, more people will drive who previously took transit. The reverse is also true. One of these situations is more desirable for myriad reasons.

As well, additional demand can be created by convenience. People will make trips they otherwise never would have if it’s easier to make them.

interdimensionalmeme ,

Communist transportation will never ever ever ever ever ever ever be easier than driving.

Because driving is “get in the car, go directly to destination”

Public transport adds walk to transport rally point, wait, follow a compromise route to accomodate other travellers with many stop, consider all the strangers gazing and judging you, arrive at not your destination, walk 5 to 20 mins to your actual destination. Plus you must carry any object on your person while navigating the terrain (good luck hauling 50lbs of groceries).

I am simply not interested in this nightmare, find a solution that isn’t horrible.

And NOoo I don’t want Musks robot taxis from the “you will own nothing” dystopia.

Signtist ,

As much as I personally disagree with you, given that all you’re thinking about is your own benefit, and not any of the myriad of benefits to the city, the world, the people who can’t afford cars, etc, I understand that your outlook is shared by the vast majority of Americans, and can’t be ignored if we ever hope to have an effective public transport system.

We’re going to need to somehow devise a system so convenient that it actually sounds attractive to the huge amount of people who spend 10%+ of their paycheck on car payments not because they have to, but because they want to.

interdimensionalmeme ,

I would love public transport that is actually better than a car. I can’t imagine how that could happen. So what they will probably do is cripple car users until it is intolerable to use. Like make it cost more than your yearly salary just for the license and insurance, plus 10x the price of fuel with taxes.

driving_crooner ,
@driving_crooner@lemmy.eco.br avatar

By “directly to destination” did you mean the gigantic parking lot necessary to accommodate every car? You are going to walk anyway, the different is that you’re walking in the most horrible hostile car centric space instead of one made for humans.

interdimensionalmeme ,

If there isn’t parking, that mean the place is full. Go somewhere else. Or re-evaluate if you really need to go there, the answer is probably no.

interdimensionalmeme ,

I live in the forest, we have no problem with parking. There is space everywhere. I don’t mind a little mud on my tires and shoes, not everywhere has to be concrete

interdimensionalmeme ,

My car is electric, if tgat’s a problem then I would instead recommend to make city cars not illegal. Personally I’ve always wanted a single seat car that weights as much as a motor cycle.

FluffyPotato ,

It already is, finding a parking spot and then walking through a parking lot is a lot less convenient than walking from the tram stop to the store and it’s roughly the same distance. I sold my car after moving to the city because public transit is so much more convenient.

Annoyed_Crabby ,

Have you considered that within city, parking is a huge problem? Maybe in american suburb the parking space is big enough to fit housing for 100 families, but in the city they don’t have such luxury.

Now just like what you said about the public transport, for driving it’s get in the car, facing 20 min of traffic jam, waiting for traffic light, waiting for traffic light, waiting for another traffic light, reach your destination, find a parking, saw a spot, too bad because big dumb pickup truck double park because the parking spot is too small to fit that ego-sized vehicle, looking for another parking spot, finally found one but have to make 5 min walk to the shop. Now do the return trip.

Xavienth ,

The joke is on you. There are places where it already is easier than driving. What do such places have in common? There are so many people that having everyone drive is literally impossible to accommodate. You wouldn’t drive in Manhattan, Tokyo, or Seoul. It literally makes absolutely no sense to. In these cities, public transit is faster and way more convenient.

Smaller cities can replicate this effect by just… not outrageously favouring car infrastructure like they do today in North America. That doesn’t mean exclusively making driving worse, it means making public transit better at the same time with the freed up funding. And the freed up money is a lot, car infrastructure is super expensive. More routes with more stops at higher frequencies are made possible because of higher ridership, which increases convenience and makes it more likely you will get almost exactly from your origin to your destination.

But the American brain cannot conceive of this. “Communist transportation” fucking lmao. What if we made cities more liveable for humans, not for cars? Nah we can’t do that that’s communism.

interdimensionalmeme ,

The problem concentrating everyone like a pack of sardines, then you can’t move or live anyway.

There wouldn’t be a problem if the traffic wasn’t all trying to go to the same place.

Xavienth ,

So you think we should decentralize cities. Make it so you don’t need to go downtown for everything. Everything you need would be within 15 minutes of walking.

… A fifteen minute city perhaps.

TheWolfOfSouthEnd ,

I prefer transit, unfortunately for me it wouldn’t be practical, maybe even before the half of our railway lines got removed.

bort ,

When you add a new lane to a road, people think that the traffic will be easier there, so they take that route instead of their normal one

so for these people the new lane will create marginal improvement, right?

Vrtrx ,

That’s the thing: Technically yes. It temporarily improves traffic. But only temporarily. IDK about you but spending billions of dollars to only temporarily improve traffic and then it ending up the same or even worse than before doesn’t sound like a good investment to me.

bort ,

But only temporarily

but is it?

I thought the temporal improvement would be for everyone who already used the high way (because they will get to their destination a little bit faster). And for the few extra people, who start to use the highway but didn’t use it before, the improvment will stay.

EldritchFeminity ,

That’s the thing, the number of new cars using that road ends up being at least one additional lane’s worth. So traffic moves at the same speed as it was before the extra lane, just now with one more lane’s worth of cars on that road.

If anything, you might see marginally better traffic on other roads because of the cars that started using the new lane, but you’d be talking about a handful of cars per road. Probably not enough for any discernible change in travel time or congestion, and each new lane you add later will have diminishing returns because it will be a smaller fraction of the total number of lanes coming from any specific direction.

xavier666 ,

If you make B less risky, you’ll get a new category of people. If you make it more risky, you’ll lose categories.

Can you explain what this part means? What do you mean by category here?

Hammocks4All ,

Yes. That wasn’t the best word choice; maybe “group” would have been better. I meant groups of people who are willing to take some level of risk. Imagine the categories are “low risk takers”, “medium risk takers”, and “high risk takers”.

Compared to A paying out $40, if you make B $50-n you’ll only get the high risk takers choosing B. If you make it $70-n you’ll get high and medium risk takers. If you make it $120-n you’ll get almost everybody.

If risk taking is a value between 0 and 1, the categories are groups of people inside certain intervals. For example, low could be [0, 1/3), medium could be [1/3, 2/3), and high could be [2/3, 1].

FuryMaker ,

I keep thinking this during my daily commute along a 3 lane freeway. If a bus/truck overtakes another bus/truck (often), it basically becomes a single lane freeway. And during peak, that little manoeuvre is going to cost you and hundreds of cars behind you, probably for a long time.

psud ,

My small city’s main suburb to centre link is a 100km/h, two lane each way parkway, until it merges with a similar road from a different centre, grows to 3 lanes each way, and slows down sharply as it gets close to the centre

Between the last traffic lights and the spaghetti junction that merges it with a similar road it’s free flowing and fine. The slow lane goes about 95, the fast lane about 100 to 110, with occasional slight slowdowns when a 95km/h car catches up with a slower one

But on that stretch there’s about 300 metres of slow traffic due to a fixed speed camera. People going 95 who think their speedometer might be wrong the opposite way to which it is slow to 80; people doing 110 slow to well below 100, people following too close brake heavily, the fast lane ends up with a standing wave with a peak (or is it a trough?) of 60km/h

Then as you get past the camera it gets loud with even the slow cars rebelling against the slowdown give much throttle. That camera must cost so much CO2. I doubt it catches anyone except during the lightest traffic times. In even medium traffic you couldn’t speed through that bit of road if you tried
