Better crossing management - It is possible

[douglasrac]

There is a project being developed to manage cars that will drive by themselves. It's actually working already. And the below is a system to manage how cars will handle by themselves to cross crossings in roads and even avenues with 6 lanes each side!

And that is what CiM should use to handle it's crossings as for now it's a bit messy.

Visit the website and download the videos. What you see are cars going very close to each other but never crashing and almost zero stop at crossings. It's a big flow of cars and no queues. They also have different speeds to simulate small cars, vans, sedans and SVUs.

P.S.: It wouldn't look realistic in CiM, but SURE is a very interesting thing.
Taking the approach to an extreme, you can see what the reservation system enables with 6 lanes in each direction and granularity of 48.

Simulator available. Make your own parameters: http://www.cs.utexas.edu/~aim/oldsim/simulate.cgi

uhh, this would not be too realistic, would it?

Maybe there is a way to change the code (didn't see in the simulator) to have a minimum distance between cars.

I managed to "break" it...
In the first few moments after I started the simulation cars slowed down to a near stop when they approached the intersection. After a few more moments cars comletely stopped just after they appeared, and created a block.
You can see in the screenshot that on every lane there is a row of cars (some of them dark-blue).

LOL! Might be worth it reporting to them.

This would be cool in a space-city setting, perhaps, but maybe not in a modern-day human city

would be nice with the traffic lights though, that is quite realistic in this simulator.
