The other thing that really seems to make the biggest difference (in combination with better acceleration) is following distance, which is another thing that presumably gets less important with autonomous cars because you don't really have to account for a relatively slow reaction time or poor braking. The observation on acceleration does make me wonder whether teaching proper merging etiquette better (reach freeway…
How do autonomous cars deal with cheap or worn tyres? Is there still a lot of allowance for braking distance?
Needs an American mode where people don’t know they should stick to the right-most lane, unless passing.
The more lanes you add, the more cars you get. Adding more lanes doesn't solve traffic issues. https://en.wikipedia.org/wiki/Induced_demand#Induced_traffic...
Rush hour is like pouring a 5gal bucket into a sink. You can't reasonably handle that all at once will have some water in it until it all makes its way through the pipe. But you have to be insane to use that as an argument against making the pipe bigger. Increasing the max capacity of the pipe (so more lanes, in the case of highways) means that it can have normal flow before it starts backing up. The "induces" demand because at the margins some people who were voluntarily changing their usage times to avoid the peak hours will commute at peak hours.
I am intentionally trying to use generic language here because this isn't a unique phenomenon to highways.
I've always wanted to program something like this. What are good references to simulation programming to handle this kind of use case?
On the ring map, with default settings, just stopping traffic with the traffic light for a second produces the dreaded rubber-band effect propagating forever around the circle. Fun simulator!
Perhaps these questions are appropriate for this post. I'm beginning to delve into this space and I've not managed to get any satisfactory answers to these questions, despite my month(s) long search. 1) How does one build a traffic (i.e state-space system), forgetting the visualization aspect of things ? Just generating sparse matrices, and adding elements to interact (add/subtract) from these matrices would be a gre…
2) Another option with much less detailed traffic simulation, but much more UI focus, is abstreet.org
Things like this are cool. What I would be curious to see though, rather than setting global parameters (i.e., politeness), would be to have each agent have its own politeness score (as well as other attributes). Models like the one linked to here work as if each agent is a particle, rather than autonomous decision-maker adapting to their circumstances locked in long-term, iterated games with other anonymous drivers.…
I live in a small town that has extra polite drivers. It was really confusing for a while. Eventually I realized that it was a practical response to the overall street layout, with a limited number of main streets, and different areas of town not being well connected. Stopping to let others cross improves the overall traffic flow - if no one did it, traffic would just be backed up for miles.
