Abstract
Raskrižja u razini najčešći su tip raskrižja koji se primjenjuje u urbanim područjima. Sve veću primjenu među raskrižjima u razini nalaze i kružna raskrižja. Na značajnim lokacijama, kao što su izlazi sa autocesta, kružna raskrižja osim kao mjera smirenja prometa moraju osigurati i dostatan kapacitet. U slučajevima većeg prometnog opterećenja na takvim lokacijama u nekim slučajevima izvode se dvotračna kružna raskrižja, s pretpostavkom da osiguravaju mnogo veći kapacitet u odnosu na jednotračna raskrižja. Često se u tim slučajevima sigurnost prometa, čija razina kod dvotračnih raskrižja značajno opada, stavlja u drugi plan. Upravo niska razina sigurnosti bila je i razlog odabira problematičnog dvotračnog raskrižja u ovom radu. Na temelju terenskog obilaska, prikupljanja podataka o prometnom opterećenju, brzina u zoni raskrižja, geometriji raskrižja te prometrim nesrećama napravljena je detaljna analiza postojećeg stanja na raskrižju. Analiza je potvrdila pretpostavku vrlo niske razine sigurnosti na raskrižju što je bilo polazište za odabir nekoliko potencijalnih varijantnih rješenja. Sva varijantna rješenja podrazumjevala su alternativni tip kružnih raskrižja, dva varijanta rješenja su podtipovi turbo kružnih raskrižja, a treće rješenje je flower kružno raskrižje. Kako bi se odabralo optimalno varijantno rješenje, sva su rješenja analizirana prema unaprijed definiranim kriterijima.
Abstract (english)
Level intersections are the most common type of intersection applied in urban areas. The roundabouts intersections are of increasing use among level intersections. On significant locations, such as motorway exits, roundabouts, except as a traffic calming measure, must also provide sufficient capacity. In cases of heavy traffic load in such locations, in some cases two-lane roundabouts are applied, assuming that they provide much higher capacity than one-lane intersections. In these cases, traffic safety which is significantly reduced at these type of intersections, is often put aside. The low level of safety was the reason for choosing the problematic two-lane roundabout intersection in this work. A thorough analysis of the current situation at the intersection was made on the basis of a field investigation, collection of traffic load data, speed in the intersection zone, intersection geometry and traffic accidents. The analysis confirmed the assumption of a very low level of safety at the intersection, which was the starting point for selecting several potential alternative solutions. All variant solutions implied are an alternative type of roundabout, two variant solutions were subtypes of turbo roundabouts, and the third solution was a flower roundabout. In order to choose the optimal variant solution, all solutions were analyzed according to predefined criteria.
