It is known that the rescaled one-dimensional TASEP approaches the solution of the Burgers equation. I will show a proof of this limit in the rarefaction fan using microscopic characteristics and coupling. The approach avoids the sub-additive ergodic theorem which is the crucial fact used in the original proof of Hermann Rost.
