Application of methodology for the organization of a roundabout to increase the capacity of a conventional intersection of Sofia. Part I: Geometric characteristics.

This article presents an application of a developed methodology for the reorganization and evaluation of transport situations after the conversion of the movement of cars through a conventional three-way intersection into their movement through a roundabout. The only correct approach to improving the organization of road traffic is the correct choice of solutions for the organization and reorganization of traffic on the existing road. The research carried out is checking the improvement of the conditions, organization and safety of the traffic and whether the capacity of the intersection of a particular intersection has increased before and after its reconstruction from a three-way to a roundabout. What is specific about the developed methodology and the specific proposal for the reconstruction of an intersection is that it complies with the accepted limitations of the existing street areas and checks whether the movement of cars from all traffic flows in the busiest hours of the day in terms of traffic is unhindered. The necessary research and studies have been conducted to successfully identify and implement the most effective methods and approaches for the overall organization of road traffic and street design and reconstruction of the transport infrastructure.
