Novi tip krožnega križišča: krožno križišče s ”pritisnjenimi” pasovi za desne zavijalce – ”flower roundabout”

Abstract

Recently, many of the foreign traffic-safety analyses point out the low level of traffic safety in multi-lane roundabouts. This problem is resolved in several ways in different countries however, the solution, whereby the number of conflict points is diminished (e.g. turbo roundabout) has proven to be the most successful. However, the turbo roundabout also has its deficiencies: it has conflict crossing points and larger reconstruction of the existing two-lane roundabout is needed when the turbo roundabout is to be implemented instead of the existing one. In the paper a new type of roundabout has been introduced the roundabout with âdepressedâ lanes for right turning (âthe flower-roundaboutâ). Financially speaking, the main advantage of the new type of roundabout is that it can be implemented within the dimensions of the already existing ânormalâ two-lane roundabout. From the traffic-safety point of view, the main advantage of the new type of roundabout is that it has no crossing conflict points. V zadnjem Äasu mnoge tuje prometno-varnostne analize kaÅ¾ejo na nizko raven prometne varnosti veÄpasovnih kroÅ¾nih kriÅ¾iÅ¡Ä. Ta problem v razliÄnih drÅ¾avah reÅ¡ujejo na razliÄne naÄine, kot najuspeÅ¡nejÅ¡i pa se je pokazal naÄin z zmanjÅ¡evanjem Å¡tevila konfliktnih toÄk (npr. turbo kroÅ¾no kriÅ¾iÅ¡Äe). Vendar ima tudi turbo kroÅ¾no kriÅ¾iÅ¡Äe svoje pomankljivosti: ima konfliktne toÄke kriÅ¾anja ter v primeru, da Å¾elimo izvesti turbo kroÅ¾no kriÅ¾iÅ¡Äe namesto obstojeÄega dvopasovnega kriÅ¾iÅ¡Äa, je potrebna veÄja rekonstrukcija kriÅ¾iÅ¡Äa. V prispevku je predstavljen novi tip kroÅ¾nega kriÅ¾iÅ¡Äa - kroÅ¾no kriÅ¾iÅ¡Äe s "pritisnjenimi" pasovi za desno zavijanje. Glavna prednost takÅ¡nega tipa kroÅ¾nega kriÅ¾iÅ¡Äa je, da ga je moÅ¾no izvesti znotraj meja obstojeÄega dvopasovnega kroÅ¾iÅ¡Äa. S staliÅ¡Äa prometne varnosti ta tip kroÅ¾nega kriÅ¾iÅ¡Äa nima konfliktnih toÄk kriÅ¾anja.
