ESTIMATION OF SUITABILITY OF THE CONSTRUCTION THE ROUNDABOUT ON ŠALEŠKA STREET BEFORE THE TUNNEL IN VELENJE

Pri rekonstrukciji križišč v urbanem okolju je potrebno skrbno pretehtati vse dejavnike in kriterije (projektno tehnične, prometno varnostne in kapacitetne) in se na podlagi le-teh odločiti za najustreznejšo varianto rekonstrukcije. V diplomskem delu je predstavljeno trenutno stanje obstoječega štirikrakega nivojskega križišča na cesti G1-4 v Velenju. Izvedena je podrobna kapacitetna raziskava in primerjava vseh predlaganih rešitev ter predstavitev optimalne rešitve, ki se pokaže v krožnem križišču s spiralnim potekom krožnega vozišča oz. tako imenovanem »turbo« krožnem križišču.When reconstructing intersections in urban areas a special consideration should be given to all the factors and criteria (such as project technical factor, traffic safety factor and capacity factor) and based on those factors and criteria the most appropriate option for reconstructing is made. This diploma work presents the current state of the existing four-leg type crossings on the road G1-4 in Velenje. A detailed research and comparison of all the proposed solutions were carried out and a presentation of an optimal solution, which appears to be in roundabout with a spiral course or so-called »turbo« roundabout, was made
