The Biham–Middleton–Levine traffic model for a 144 x 89 lattice, with a traffic density of 60%. The model has self-organized to a globally jammed 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. This video has been sped up such that only one in four frames is shown.
