Abstract

The article presents the results of studies that allow to reduce time delays by determining the optimal parameters of roundabouts based on the established dependencies of road characteristics on the geometric parameters of road intersections and traffic flows. In analytical studies, we identify the most effective types of configurations of the road intersection at the same level and establish the dependence of the average vehicle speed on the total traffic intensity for these configurations. Moreover, the paper establishes the dependence of the average speed on the intensity of traffic flow at different radii of the central guide island of the roundabout and the dependence of the average speed on the radius of the central guide island with different bandwidth of the carriageway on the approach to the roundabout.
