statistical analysis of historical, and traffic estimation and prediction. The filtration module is responsible for the classification of road users and detecting measurements that should be removed. Traffic estimation has been performed on the basis of the data collected by Bluetooth measuring devices and information on external conditions (e.g., temperature), all of which have been gathered in the city of Bielsko-Biala (Poland). The obtained results are very promising. The smallest average relative error between the number of cars estimated by the model and the actual traffic was less than 10%.

Przeprowadzono badania na kierowcach w czasie prowadzenia samochodu w warunkach rzeczywistego ruchu drogowego. Zarejestrowane modalności poddano analizie w celu oceny wpływu różnych sytuacji drogowych na wartości sygnałów biomedycznych. Na tej podstawie określono przydatność wybranych modalności w dalszych badaniach nad systemem wczesnego ostrzegania kierowców przed zagrożeniami wynikającymi z ich złego stanu psychofizjologicznego.

carried out on drivers while driving in real traffic. Registered modalities have been analyzed to assess the impact of different traffic situations on the value of biomedical signals. On this basis the usefulness of selected modalities for further studies on early warning system drivers against the dangers arising from their bad psychophysiological state has been assessed.
