videos are arguably even stronger and certainly deserve their own FP status. The video quality is as high as I could get it to be with the Ogg Theora codec (which is the only one that
Knowledge supports) whilst maintaining a reasonable filesize. Unfortunately, due to the limitations of Theora, there are some minor artifacts; nevertheless, these do not detract significantly from the quality. These videos ought to be added to the

Every time, all the cars of the same colour try to move one step if there is no car in front of it. Please note that the video has been sped up such that only one in four frames is shown.

As an editor who has made a number of animations myself for donating to
Knowledge, I know first hand just how much time and effort this sort of thing requires. No single fixed image could demonstrate the concept of “traffic increasingly jamming up” than an animation such as this. Having an animation

Since the non-intermediate phases tend to dominate more, especially at extreme traffic concentrations; and were discovered earlier (in fact the original paper by Biham, Middleton, and Levine only talks about the jammed and free flowing phases and not the intermediate ones), the EV with these

It's the transition from free flowing to completely jammed as a function of density, with the transitional states in between, that give the sequence it's EV, the individual animations aren't that informative.--

What Greg said. More than "a pretty animation", this is a technically sound, factually correct piece -- which makes it doubly valuable.
