Theme and the title of my thesis are connected with the reconstruction of the two intersections near my home. I chose these two intersections, because of some shortcomings, which I noticed in their design. At the beginning, I briefly described the crossroads. I presented their geographical location and names of the roads that are part of the intersections. After that, I listed weaknesses of the two crossings, which could represent a potential risk for the participants in traffic. Later, I focused on the theoretical basis for the design of circular intersections and road connections, which I found in technical specifications. I also described the field exercises in which I counted traffic for both intersections and based on the results made a brief analysis of the fluidity of the traffic. In the completion of the thesis I presented ideas to enhance the safety of individual intersections. The first solution demonstrates a conceptual implementation of the roundabout and the second one demonstrates an intersection with additional lane for the left turning vehicles. In annex I added new situations of intersections, which I made in computer programme AutoCAD.
