Original - The Biham-Middleton-Levine traffic model for a 144 x 89 lattice, with a traffic density of 38%. The model has self-organized to a periodic intermediate phase. The red cars and blue cars take turns to move; the red ones only move rightwards, and the blue ones move downwards. 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.

Reason

Highly encyclopedic; quality is decent. A very good feature of these videos is that even in the static thumbnails, they convey the concept well (although it is of course better to watch the actual animation). It is unfeasible to use an animated GIF image for something with many thousands of frames. Please note that much of the encyclopedic value lies in distinguishing between the disordered and periodic intermediate phases, so it makes most sense to support these two videos as a set.

• Support I already saw this video on you user page and I wonder why you didn't put them before.-- ♫Greatorangepumpkin♫ T 09:40, 13 January 2011 (UTC)
• Overall Support I'm a bit worried about the bandwidth though; the files are nearly 100 Megs each. Is it possible shorten them to the first minute or so for the main page? Also, are we sure the ogv file format has wide enough support for the main page? Anyone who has faced a morning commute on a crowded freeway will recognize the pattern. RDBury (talk)
  • The videos have already been sped up by 4 times (i.e. 3 out of 4 frames were omitted). I think that it should be possible to shorten them further by about half, since they converge to one of the states by the time it's about halfway through. However, the remaining half should be useful to observe exactly how it is, say, periodic. Seeing as the video is streamed, the total filesize should not matter as much as the bitrate (nobody is going to download the whole movie before watching it). I think that it is quite viewable on most internet connections, but users of, say, dial up may experience unpleasant slowness. As for the support for the ogv file format, it is the default format used for videos on Wikipedia and is chosen for its free and open source codec that is, in general, highly accessible to everyone. Besides, Wikipedia has its own Java-based player or something in case the reader does not have a player that supports it. Purpy Pupple (talk) 15:51, 17 January 2011 (UTC)
    • It might actually serve to boost ogv support among the readership. JJ Harrison (talk) 00:17, 18 January 2011 (UTC)
