Alcohol is recognized as one of the factors in the occurrence of traffi c accidents, which signifi cantly aff ects the occurrence of accidents and the severity of their consequences. In this paper, the results of the pilot survey present the measures of infl uence of intoxicated drivers on the status of their motor skills and a en on in traffi c. The eff ect of alcohol is simulated using the "drunk glasses" that simulate the eff ects of the alcohol on the human body: reduced alertness, slowed reac ons, confusion, distor on of the visual fi eld, change of distance and depth percep on, narrowing of peripheral vision, poor judgment and decision making, image duplica on, lack of muscle coordina on and the like. Motor skills were tested using the "Vienna test" system which measures the reac on speed, motor skills, a en on, concentra on and the assessment of traffi c situa ons. For the purposes of this study the results of the "Vienna test" were analyzed -a driver without "drunk glasses" and wearing the glasses. Glasses for alcoholic level of 0,6 -0,8 ‰ were used in the study. Through a compara ve analysis obtained by this research we point to the impact that alcohol has on the perceptual skills of drivers.
Rezime: U radu je predstavljen model odlučivanja koji je vezan za preporučenu brzinu kretanja vozila primenom pametnih saobraćajnih znakova, kojima se u realnom vremenu preporučuje bezbedna brzina kretanja vozila. Model je zasnovan na "fuzzy logici" i primarno je namenjen za primenu na tzv. "otvorenim" deonicama puteva van naselja, na kojima važi opšte ograničenje brzine kretanja. Pružanje pravovremene informacije vozaču o preporučenoj bezbednoj brzini kretanja vozila je posebno važno na deonicama puteva na kojima dolazi do čestih promena uslova za vožnju, izazvanih promenama vremenskih prilika ili gustine saobraćaja. Na ovim deonicama poželjno je preporučiti brzinu kretanja vozila koja je adekvatna, pravovremena i koja u obzir uzima više različitih podataka koji se prikupljaju u realnom vremenu. To se ne može postići tradicionalnim saobraćajnim znakovima već znakovima koji informaciju generišu na osnovu analize više različitih parametara, koji imaju direktan uticaj na preporučenu bezbednu brzinu kretanja vozila. Rad se upravo bavi elementima pametnog odlučivanja primenom "fuzzy logike", u cilju adekvatne preporuke bezbedne brzine kretanja vozila.
