Configure an example with bad human driving --> better robot driving

[cathywu]

In the other plots, we have separate examples from separate simulations or a single simulation that shows poor robot driving --> somewhat improved robot driving. The goal here is to demonstrate a more dramatic improvement.

Preliminary example with ACC and 85 vehicles. The tau is reduced from 3 to 0.5 at the midway point.

Whereas if tau=0.5 for the entire simulation, then it looks like:

So this is a good start, but why can't the robot vehicles improve the first scenario up to the level of the second?

Perhaps with a larger reaction time (tau), the capacity of the loop is just lower. With 55 agents instead, we see:

So what's the largest number of vehicles such that the humans can achieve 25m/s?
Looks like 20 vehicles.

A full switch from human (no controller, just default behaviors) to ACC halfway:

With humans with random lane changes (randomChangeLaneFn):

Sweep of varying proportions of humans + changeFasterLaneBuilder vs robot + ACC:
