Precise emission models are so complex that their details practically are not available. The "physics" of hydrodynamic traffic models provides only ambiguous mathematical formulae. Therefore adaptive controllers iteratively improving the forecasts of a rough initial model are required that work without tuning any particular model parameters. For this purpose a simple numerical technique is reported. The stable stationary solutions of a particular model are determined. Then a simple iterative adaptive emission control grasping only the main factors is developed. It is shown that small modification of the parameters of the dynamic model have drastic influence on the emission so the use of adaptive techniques is essential.
