@yogthos How about a city like NYC that bans human driven vehicles altogether and has a network of autonomous vehicles of varying sizes constantly available on the street for both cargo and passenger travel. You need to get from brooklyn to an address in midtown? You call up a ride on your phone. One immediately drops out of traffic, picks you up, and takes you where you need to go. No human behavior caused traffic jams or accidents. For less specific destinations, bus or van sized vehicles.
thats just cars with extra steps.
good public transit does exactly this, except more efficiently.
@umbrella “good public transit does exactly this, except more efficiently.” Not really, if it is al on one electric grid. Think of it as one giant train with the cars broken up and separated.
then we would have to maintain an infinity of discrete cars, asphalt and there’s all sorts of safety implications. isn’t it cheaper to make actual trains?
now, i agree current car-centric infrastructure will make this difficult in the short and medium term, but cars exist for that and would be not problem to use in the meantime if the solution is just making them electric or self driving.
@umbrella not “just”
Why not make these cars bigger, so they can pick up and drop off a chain of multiple parties of travellers more efficiently?
Once demand’s been established, we could even do away with the phone app and just run the cars on a schedule.
This idea sounds really bussin
I don’t think automated vehicles are necessarily bad, there are some trains that are autonomous that work well as far as I know, but this in no way means that autonomous cars are a good idea. Not Just Bikes has a very interesting (albeit long, but you don’t need to watch much of it to get the gist) of how autonomous cars could make cities an absolute nightmare, I recommend it!
No. That only solves some of the issues, and creates brand new ones.
You haven’t solved the inherent inefficiencies of having everyone sit in their own cars. The same bottlenecks will still exist and will still cause congestion, only with automation you can have slightly more capacity because it’s taking out the delays between one driver moving and the driver behind reacting and starting to move as well.
All the issues with tires rubbing asphalt creating micro rubber particles will stay, as will the massively cost ineffective infrastructure needed to support mass car travel like freeway interchanges, as will the fact that you need orders of magnitude more materials to manufacture enough cars to do the job of just a few hundred trains.
And having the cars autonomous will make them even more vulnerable to cyber attacks than modern cars already are.
Also, trains are even easier to automate than cars. I live in Vancouver and we’ve had autonomous trains since 1986.
@HiddenLayer555 In NYC, my example, how many more train lines do you suppose you would need? Above ground? Underground? Are you going to lay track on every street? underground? Are you sure this would be more efficient than a network of smaller vehicles? There is no need for everyone to sit in their own car if it is all electric and automated. A single person vehicle, if if even existed, could be much smaller.
@farbel @HiddenLayer555 Not much more, PT already moves more people than private vehicles around NYC: https://a816-dohbesp.nyc.gov/IndicatorPublic/data-explorer/walking-driving-and-cycling/?id=2415#display=summary
So to get from where it is to a “no private vehicles” utopia thre isn’t that much more to do. Probably as tramways on roads that will now be closed to cars. So not that expensive. But a couple more subways for some links that need more volume would probably be needed.
