English: The BML traffic model, for a lattice of 200 x 200, with a traffic density of 30% (of which half are red, and half are blue). The red cars and blue cars take turns to move; the red ones only move upwards, and the blue ones move rightwards. Every time, all the cars of the same colour try to move one step if there is no car in front of it. Here, the model has self-organized to flow freely at top speed all the time. The mobility graph represents the number of cars that can move as a fraction of the total; the two lines represent the two different species of cars. The image was generated by my own code written with MATLAB.
