Transferring AI to the future mobility sector
Posted 11 November 2011 - 12:10 PM
this is a bit off-topic but i'm wondering how AI can be used in the future to solve urban problems like increasing traffic congestion. The reason is that I'm working on a research project on smart cities and I thought about an interlinked semantic system in which AI can be used for traffic coordination and the prevention of traffic jams.
I'm also thinking in terms of information sharing between traffic participants to predict traffic flow (which might include thoughts like robotic cars for urban areas). My assumption is that by let's say 2050 we are all so interlinked so that real-time sharing of information is easily possible and so any AI-system can be fed with all the data necessary.
The major question I'm asking myself: is it possible to develop e.g. a semantic system that can analyse all available data (gps positioning etc.) so that it can detect evolving traffic jams and inform all traffic participants who might be affected by that jam? How can AI be used to understand human mobility behavior? If you can think of any solution, just share your thoughts!

Then the cars can drive REALLY close together increasing the capacity of the existing road ways.
Basic traffic jams will not occur as they are usually caused by bad driving, people going from the outside lane to a slip road causing following drivers to brake, causing drivers behind them to brake harder, etc.

Anyways, first thing that popped into my mind was securing such a system. Oh what a hacker could do with this...

There is also the question of ownership: if you own the car, you'd want to park it when it's not in use (thus, it takes away part of the very limited space in cities). If people do not own the vehicles anymore, anybody could use them when needed. This would be like public transport but with a lot more flexibility. Do you think that could be a feasible solution?
Actually I wondered that if there is no central coordination of traffic, it is really hard for any hacker to get into the system. Because if decentralized agents share information with each other in a very flexible way, you'd need to hack every single unit in order to affect the system.

Abu Dhabi has the Masdar system. Take a look at that and other projects in that city.
As for security, you are already going down a common road, pun intended. "Hey, I don't need to worry about it as much, because it's a decentralized system." How do the cars coordinate? Ever hear of a worm virus?

In America people strongly depend on their cars, so you would have to provide flexible personal vehicles that take you from home to work (and not only to the next train station etc.). That would also increase costs and thus limit the feasibility of such a project.
Thanks for the Masdar hint, I already know the project and I've also had a look into it. Functions pretty well but it's a totally new city with tremendous up-front investments. I highly doubt that you could just copy their system and introduce it to other existing cities (I mean infrastructure is rigid, you can't just easily replace it).
Security aspect: I didn't mean that about wouldn't worry about it because if security can't be provided you don't need to implement such a system. I just wanted to hear some thoughts on how security could be provided. Nonetheless, IMO a decentralized system is securer than a centralized system :)

Having a seperate series of small ai's controlling local vehicles is much more secure than having HAL sat somewhere running the entire road network.
However you need to think about how the ai would work as a series of layers
Layer 1 Controlling the vehicle
Layer 2 Predicting traffic flow
Layer 3 Route planning
Layer 4 Network control
Layers 1-3 would be in the car, layer 4 an external ai that controls things like traffic lights.
Layer 2 would handle a car that needs to change lane because it is leaving the current road network. All the cars around it would vary there speed to allow safe passage.
Layer 4 would talk to ai's and advise them of local traffic problems and this would be an input into layer 3
I think it would work really well, but the possibility of a hacker gaining control of the system is a bit scary.
Having said that, in the last 5 days I have spent about 25 hours on british motorways. I think a hacker would probably be safer than some of the drivers I have just seen.

Actually, assuming you can create a secure way to note vehicles, it would not be hard to compute the best traffic situation.
The primary problem I can see is that what may be best overall may not be best for me. If the best way to keep traffic to a minimum is to route me out of town then back in, I'd be plenty pissed...

I managed to get one route which I flagged as "avoid motorways" "fastest route" from Southampton to Liverpool
The route was Southampton to Bristol, ferry to Ireland, up the east coast of Ireland, ferry to Liverpool
