The paper postulates a method of the online control of neural net in accordance with the features of the longitudinal ventilation using jet ventilators for highway tunnels with one direction traffic. An online control model of tunnel ventilation is established based on the method, upon which a dynamic simulated emulation of the process of longitudinal tunnel ventilation is carried out incorporating the model of aerodynamics and the model of contamination. It is shown that good results can be obtained by using the online control of the neural net for the longitudinal ventilation of highway tunnels.
