Abstract

Kretanje vozila u cestovnom prometu uvjetovano je prometnim i oblikovnim elementima trase ceste. Osim pravaca u tlocrtne elemente ceste pripadaju kružni lukovi i prijelaznice pri čemu kružni lukovi i prijelaznice čine tlocrtne zavoje. U odnosu na pravce, prilikom projektiranja ili rekonstrukcije tlocrtnih zavoja potrebno je primjenjivati prometno-oblikovne elementi koji prije svega omogućavaju postupnu promjenu radijalnog ubrzanja te zaustavnu i pretjecanju preglednost. Određivanje graničnih brzina kretanja vozila u zavoju stoga je značajan element sigurnosti cestovnog prometa. Kretanjem vozila u zavoju brzinom koja je veća od granične brzine koja je određena projektnim zadatkom, podrazumijeva i mogućnost zanošenja-klizanja ili prevrtanja vozila. Kako ne bi došlo do navedenog prometno-tehnički elementi ceste u zavoju potrebno je uskladiti sa mjerodavnim vozilom, njegovim tehničkim karakteristikama te uvjetima okoline koji prevladavaju na tom cijelu ceste.

Abstract (english)

The movement of vehicles in road traffic is conditioned by the traffic and design elements of the road route. In addition to the directions, the circular arches and crossings belong to the road elements, whereby the circular arches and crossings form the ground turns. In relation to the directions, when designing or reconstructing the bends, it is necessary to apply traffic-shaped elements, which first of all enable a gradual change of radial acceleration and stop and overtake transparency. Determining the cornering speed of vehicles in a turn is therefore a significant element of road safety. Moving the vehicle in a turn at a speed greater than the speed limit determined by the project task also implies the possibility of drifting-sliding or overturning the vehicle. In order not to come to the fore, the traffic-technical elements of the bend in the bend must be harmonized with the relevant vehicle, its technical characteristics and environmental conditions prevailing on that whole road.
