Alternative Solutions for Reconstruction of the Existing Traffic Lights Intersection "Bolnica" in Poreč

Zadatak ovog diplomskog rada bio je napraviti analizu postojećeg stanja raskrižja, napraviti varijantna rješenja za rekonstrukciju postojećeg raskrižja te naposljetku odabrati optimalno prometno-građevinsko rješenje. Napravljena je analiza postojećeg stanja raskrižja te je utvrđeno kako raskrižje sadrži veliki broj kolizionih točaka koje smanjuju prometnu sigurnost raskrižja. Provozne brzine na glavnom smjeru su prevelike te preglednost za sporedne smjerove nije zadovoljena. Na temelju analize postojećeg stanja prikazana su 3 varijantna rješenja za rekonstrukciju postojećeg raskrižja. Svako varijantno rješenje analiziralo se prema nekoliko unaprijed definiranih kriterija. Varijantna rješenja su se vrednovala prema kriterijima te je naposljetku odabrano optimalno rješenje kao ono koje je postiglo najveći zbroj bodova prema definiranim kriterijima.The task of this thesis is to make an analysis of the existing condition of the intersection, to make variant solutions for the reconstruction of the existing intersection and finally to choose the optimal traffic solution. An analysis of the current condition of the intersection was made and it was determined that the intersection contains a large number of collision points that reduce the traffic safety of the intersection. Transit speeds on the main route are too high and visibility for side routes does not fulfill. According to the analysis of the existing condition, 3 variant solutions for the reconstruction of the existing intersection are presented. Each variant solution was analyzed according to traffic criteria. Variant solutions were evaluated according to the criteria and the optimal solution was selected, which ultimately had the largest sum of points
