To the right is the result of an example simulation run of the Nagel–Schreckenberg model, with maximum velocity 5, density of cars 0.35 and probability of deceleration p = 0.3. It is a road of 100 cells. Cars are shown as black dots, and so, for example, if the road had a single car on it the plot would be white except for a single black line of slope −1/5 (maximum velocity = 5). The lines have slopes that are steeper, indicating that jamming is slowing the cars down. Small traffic jams show up as dark bands, i.e., groups of cars that are nose-to-tail and moving slowly to the right. The rippling of the bands is due to the randomization step.
