This doesn't mention the most economically sound and complete solution to traffic: dynamic congestion pricing on roads.
Due to the effects described in the article, entering a road that's close to congested imposes negative externalities due to the delay on everyone behind you, even higher if you are pushing the road below optimal throughput. Push that externality into the price, and suddenly drivers will change their behavior in the desired fashion:
1. People will move their travel to less expensive times. Even if no other change occurs than people waiting for prices to fall, the roads operate at much higher throughput due to never getting into the region of diminishing throughput.
2. People will carpool/vanpool/mass transit- no need for any special treatment for transit, a bus with 50+ people can simply outbid most cars on the road for space, even accounting for the difference in road space taken by the bus. With the economic incentive in place, you'd even expect private buses/etc to pop up spontaneously. Right now, its rarely worth it to pool/bus- it adds extra time for you, but the benefit to the road you never see. With proper pricing, its still faster to take a car, but a lot more expensive- and the carpool/bus/etc is still probably faster than driving would be with congested roads.
3. Similarly, the high prices will incentivize alternatives such as biking, subways, etc, and give very good information on exactly what routes are in high demand when, estimates of how much an improvement would be worth, etc.
Naw, the most economic solution is to make bigger bumpers and let cars push each other forward.
Think about a hose. If you have it at a certain flow and then increase the flow the water doesn't go out faster because it wants it. It flows faster because it's being pushed.
Same thing with cars, as more cars get onto the highway you want them to go at a higher speed so that the throughput matches the on ramp. We just need to cut down the number of 4 lane highways so that we have space to put exit ramps on both sides of a 2 lane highway but the increased speed will make up for it.
How do you propose people find out the cost of traveling if the pricing is dynamic? People won’t check beforehand, and they’ll already be in their cars when they find out the cost
Navigation/maps providers like Google/Apple maps, etc, will incorporate price estimates as well as time estimates- they can even show multiple options if there are price-time tradeoffs available.
At high demand times, you have to be very rich indeed to outbid a full bus without even thinking about it. There aren't enough people who can do that.
But say this does happen a lot-this means rich people pay enormous road use fees, which can then be used for road maintenance, construction, and improvement, as well as other transit infrastructure!
So, the rich willingly subsidize infrastructure for everyone? Seems like a win-win!
That's a nice pipe dream, but what would happen in reality is that all of the congestion fees would go to the rich (perhaps in the form of tax cuts), who would use it to buy more stock, bribe some politicians to ban buses, and then triple the congestion charge because fuck you.
The congestion fees would go to the government responsible for the roads. Of course, they could be captured by the rich, but most governments spend most of their money not on the rich.
You'd set the congestion charge, by law (at least on public roads), to the minimum required for efficient road use- not the revenue maximizing price, which would likely be much higher due to monopoly.
Why do people insist on this tired unimaginative trope. We have the past and present to look at. We know how these things work.
The rules will be crafted, the commas in the laws placed, the contracts handed out, to support those who supported the endeavor. If the plumber's trade group agrees to support it their vans will be exempt. If Palantir supports it, the RFP will be written to make it nigh on impossible to not buy their stuff. No matter how flagrant the badness of the system, if the tech industry makes even a cent, the comment section full of techies will engage in olympic level mental gymnastics and not just do bending over backwards but doing full on backflips to justify the goodness of the system. If the bus drivers have such a comment section they'll do it too.
This is how things were. This is how they are. This is how they will be. Well, right up until the point where the rest of society gets sick of our shit and leaves us in a big communal hole or gives us a free shower or whatever happens to the fashionable way to do that thing is at that point in the future...
But I suppose maybe you're right and they'll throw a few pennies of tax cuts at it if they just need a little upper middle class support to drag it across the finish line.
And also in essentially any relevant private market for goods and services where capacity is limited, especially when there are more and less desirable times.
