Abstract

Za postizanje sigurnog i nesmetanog odvijanja prometa na raskrižju u razini i njegovim prilazima, jedan od najbitnijih uvjeta koji treba biti zadovoljen je uvjet preglednosti. U odnosu na otvoreni potez ceste, na raskrižjima u razini postoji puno više konfliktnih točaka, uzrokovanih prometnim radnjama isplitanja, uplitanja, preplitanja i križanja prometnih tokova na površini raskrižja, što rezultira većom opasnošću od sudara vozila. Osiguranjem potrebne preglednosti i prikladnom regulacijom prometa ta se opasnost može smanjiti. Potrebna preglednost ovisi o prilaznoj brzini vozila i udaljenosti koju vozilo prijeđe tijekom vremena uočavanja, reakcije i kočenja. U ovom radu prikazana je metodologija ispitivanja preglednosti na izvangradskim jednotračnim kružnim raskrižjima dana u australskim i hrvatskim smjernicama za projektiranje kružnih raskrižja. Navedeni postupci primijenjeni su u ispitivanju preglednosti na jednom jednotračnom kružnom raskrižju za brzinu prilaska vozila 50 km/h te je dana usporedba rezultata ispitivanja.

Abstract (english)

To achieve safe and unobstructed traffic flow at the intersection and its approaches, one of the most important conditions that needs to be met is an adequate sight distance. Compared to the open parts of the road, there are many more points of conflict at intersections, caused by traffic actions on the intersection surface, resulting in a higher risk of vehicle collision. This risk can be reduced by ensuring the necessary sight distance and appropriate traffic regulations. Required sight distance depends on approaching speed of the vehicle and distance that vehicle passes during the observation, reaction and braking time. This assignment explains methodology of obtaining sight distance on a single-lane rural roundabout given by Australian and Croatian norms on designing roundabouts. Methods are then applied on a single-lane rural roundabout with approaching vehicle speed of 50 km/h and the results comparison is given.
