Individual groups of vehicles affect the conditions of traffic streams to different extent. For a given group of vehicles, this effect should be approached as a variable determined by some geometrical and traffic properties. This impact can be estimated by using one of the models used for the purpose. One of such models is a model based on comparisons speed of group of vehicles in traffic stream. This paper presents the results of the measurements of the spatial average velocity of vehicles that cross circular intersections (usually roundabouts) and the analyses of the effect of selected geometrical parameters on the velocity of vehicles crossing an intersection and consequently the car equivalents for heavy vehicles.
