Future construction of cars requires knowledge about dynamics of driver's, because vitally affecting his responses to unexpected situations in traffic. Unpredictable situations in the driving of the car are real, because the traffic is crowded on the road. After detecting the models in the brain driver's, we could understand how models influencing his reaction on the traffic situations. Research results, supported by new advances in automation and information technology, can be used in the areas of so-called "intelligent systems to support decision of driver's" and "intelligent transport systems". This article explains a new conceptual model of driver behaviour, which is able to characterize the response of the driver in the car, from the "intelligent control system driver/car/traffic situation" point of view. In the paper the hypothesis is formulated, that immediate dynamics of driver's (delay, time constant and also controller structure), is create as sum of constant neuro physiological characteristics (muscles and nerves) and variable characteristics created in the brain. Variable characteristics are generating from "models of the traffic situations", which are continually adapted intra brain of driver's. The article outlined the verification of this model using description of measured reactions in real time.
