This does a great job of demonstrating how increasing acceleration decreases traffic. 2m/s/s is 5mph/s, and helps a lot: Cars in front get out of the way faster

This does a great job of demonstrating how increasing acceleration decreases traffic. 2m/s/s is 5mph/s, and helps a lot: Cars in front get out of the way faster. Lazy acceleration, while more accurate to what I see on the road, causes gridlock and traffic waves.
Perhaps more surprisingly, /reducing/ comf(ortable?) deceleration keeps things running smoother than higher values.

It reduces the number of cars flowing into the traffic jam temporarily, which helps to smooth out the overall flow.
- jrootabega 8y agoMy gut tells me that you should just gravitate towards the area of less cars. If the road ahead is clear or clearer, higher acceleration is better for everyone. If the road ahead is saturated but clearer behind, lower acceleration is better. If it's saturated in front and behind, good luck.
